The “Silicon Crossroads”: A visit to BOI Thailand as the nation bets big on chips

Backed by a national strategy targeting $79 billion in investment, Thailand is rapidly repositioning itself within the global semiconductor value chain. From advanced packaging and photonics to talent development and industrial infrastructure, a recent tour of the country’s emerging ecosystem reveals a nation determined to become a strategic force in the semiconductor industry.

BANGKOK – Walking through the halls of Thailand Board of Investment (BOI) 3 weeks back, one can feel the shift in the air. It is no longer just about tourism or automotive parts. There is a quiet, determined hum of ambition focused squarely on the trillion-dollar semiconductor industry.

I was respectfully invited by BOI to Bangkok to understand the noise. For years, Southeast Asia’s semiconductor narrative has been dominated by Malaysia’s packaging stronghold and Vietnam’s supply chain shift. But during my visit with BOI officials and a review of the newly unveiled National Semiconductor and Advanced Electronics Strategy, it became clear: Thailand is no longer content being just an assembly line. It wants to become a “Tech Owner.”

From “Made in Thailand” to “Created in Thailand”
Over strong Thai tea, senior officials of BOI Ms. Tanita Sirisup, Deputy Secretary General and Ms Anin Meksukai – Director Foreign Investment Marketing Division walked me through their “Semiconductor Roadmap 2030–2050.” The goal is to secure over THB 2.5 trillion (approx. $79 billion USD) in investment over the next 25 years and train more than 230,000 skilled workers. The BOI has introduced an “A1+” incentive category for front-end wafer fabrication and advanced packaging (chiplet, SiC, GaN), offering a 13 to 15 years corporate tax exemption. More importantly, they’ve partnered with Customs to prevent illicit transshipment – a mature move that signals Thailand takes supply chain integrity seriously. The Thai government has set a target to attract over 2.5 trillion Thai Baht.

But the more immediate headline is the pivot in value chain positioning.

Historically, Thailand has been known as a manufacturing hub for hard disk drives and basic automotive electronics. However, the new strategy, reviewed by the National Semiconductor and Advanced Electronics Policy Committee, explicitly aims to pull the country “upstream.”

“We are focusing on segments where we already have supply-chain depth,” as Ms. Tanita Sirisup, Deputy Secretary General from BOI explained during our briefing, pointing to five key target groups: Power, Sensor, Photonics, Analog, and Discrete chips. These are not bleeding-edge logic chips (like CPUs) but the essential components driving the Electric Vehicle (EV) and AI data centre revolution—sectors where Thailand already hosts massive manufacturing bases.

The “Pillars” of Incentives
During this visit, I reviewed the BOI’s playbook for luring global giants. It is arguably the most aggressive incentive structure in the region.

To move beyond Outsourced Semiconductor Assembly and Test (OSAT) into wafer fabrication, the BOI is offering the “A1+” super cluster. This includes:

• Long Tax Holidays: Up to 15 years of corporate income tax exemption for front-end wafer fabrication or advanced packaging (Chiplet, SiC).
• The Talent War: Recognizing that engineers are the bottleneck, the BOI has capped the personal income tax for foreign experts at 15%—a dramatic cut from the standard top rate—to lure talent from Taiwan, Korea, and the US.
• Infrastructure: Assurance of “green” energy stability and water security for fab-adjacent parks.

Ms Anin Meksukai – Director Foreign Investment Marketing Division proudly noted that this strategy is already bearing fruit. During a recent investment mission to the United States in April 2026, the BOI secured a major commitment from Phononic (a cooling chip manufacturer for Nvidia systems) to relocate upstream material production to Thailand by 2027.

“By 2030, the market will be worth $1 trillion,” the BOI’s secretary general Narit Therdsteerasukdi has stated publicly. “This roadmap ensures Thailand isn’t just a consumer of technology, but a designer and producer”.

Between 2018 and November 2025, Thailand attracted 1,748 investment promotion applications in the electrical and electronics sector, worth 1.17 trillion baht, representing 19 percent of total promoted investment — the largest single sector by value. The BOI joined SEMI as a member in March 2026 and is already in conversations about bringing SEMICON to Thai soil.

From talent to testing: Mahanakorn, TMEC and microchip
No strategy works without people. At Mahanakorn University of Technology (MUT), I saw boot camps that pack a full semiconductor module into 12 days. Dr. Panavy Pookaiyaudom – President of MUT (a legend in Thai engineering) showed me their cleanroom-in-a-classroom concept. MUT also hosts a National Semiconductor Training Centre, churning out technicians ready for fabs.

MUT has established semiconductor and electronics engineering programs specifically calibrated to meet the needs of the companies setting up operations nearby. Faculty members spoke candidly about the challenge: industry moves faster than curriculum can follow, which has forced closer collaboration with manufacturers. BOI-facilitated linkages between companies like those I would visit later in the week and universities like MUT mean that students are increasingly working with real process equipment, real design tools, and real project briefs from companies that intend to hire them.

A short drive away, the Thai Microelectronics Centre (TMEC) operates as Thailand’s first IC foundry prototype line. They’re developing MEMS pressure sensors for automotive and medical use.

No visit to Thailand’s semiconductor ecosystem is complete without a trip to the Thai Microelectronics Center in Chachoengsao province, about 90 minutes east of Bangkok in the Eastern Economic Corridor. TMEC is, simply put, Thailand’s most strategically irreplaceable asset in this industry. Founded in 1997 and operational since April 2004, it is the country’s first and only research-and-development fab capable of small-volume production wafer work.

TMEC is the R&D bridge between academia and industry – and they recently signed an MOU with Lumentum International (Thailand) to co-develop photonics packaging mentions Adisorn Tuantranont – Director TMEC.

Speaking of industry, Microchip Thailand (their massive backend facility in Chonburi) is anything but sleepy. I toured their high-voltage test floors and saw how they’re expanding capacity for SiC devices. Arun Wellchan – Finance Director Microchip told me they’re now handling wafer-level chip-scale packaging (WLCSP) – a step up from traditional lead frame assembly.

Few names carry more weight in the microcontroller and mixed-signal space than Microchip Technology, and the Arizona-headquartered giant has made Thailand a meaningful node in its global production network. Microchip is a handful of US companies with 4,600 employees in Thailand, driving a combined 60 BOI-approved semiconductor projects worth more than 32 billion baht, a figure that reflects the depth of American confidence in Thailand’s manufacturing credentials.

EIC semiconductor, UniEQ and Amata smart city
My first facility visit took me to the Lat Krabang Industrial Estate on Bangkok’s eastern fringe, where EIC Semiconductor operates from within the I-EA-T Free Zone. EIC is one of those companies that rarely makes headlines precisely because it does exactly what it promises, at volume, with consistency. The firm manufactures and supplies high-quality discrete semiconductors, and its portfolio is staggering in breadth: over 10,000 parts across more than 50 package types, covering the full spectrum of diode technology from rectifiers and high-speed diodes to small signal, Zener, and transient voltage suppressors. A homegrown OSAT player that has quietly grown to 500 employees. EIC specializes in high-reliability packaging for automotive and industrial, and they’re now qualifying copper clip bonding.

One surprise was UniEQ Integrated Technology, a Thai Chinese joint venture, which is a subsidiary of Foxsemicon (Fiti) Group in Thailand. Their Project Management – Thailand Operation, Alex Sun proudly showed me a tape-out done entirely in Thailand. UniEQ Integrated Technology showcased advanced precision engineering capabilities supporting semiconductor and electronics production environments. Conversation there with focused on automation, cleanroom systems, and supply-chain localization — areas increasingly important as companies seek greater resilience following years of global disruption.

No semiconductor ecosystem exists without industrial infrastructure, and in Thailand, that infrastructure story is largely the story of Amata Corporation. My visit to Amata Smart City the company’s flagship integrated industrial development in Chonburi was one of the most visually arresting of the trip (being escorted by AMATA’s own traffic police). Amata isn’t just an industrial estate; it is an attempt to design the physical environment of advanced manufacturing from first principles, integrating energy systems, logistics, digital infrastructure, and workforce amenities into a coherent urban proposition for industrial tenants.

All this is happening inside Amata Smart City in Chonburi. Think of it as a living lab: 5G, smart grid, and an industrial IoT backbone that connects factories to a central data platform. Amata’s executives Kazushige Kobayashi – Section Manager Sales & Marketing and Claudia Nonthitipong- Bieri- Department Manager – Corporate Communications at AMATA Corporation told me they’re reserving land for a dedicated semiconductor park, complete with shared chemical and waste treatment – a gamechanger for small and mid-sized OSATs.

Together, these visits illustrated that Thailand’s semiconductor ecosystem is not emerging from scratch. It is being built upon decades of manufacturing expertise in electronics, automotive systems, hard drives, and industrial automation.

SUBCON 2026 opening ceremony
Wednesday morning, May 13, I joined several thousand others at the Bangkok International Trade and Exhibition Centre for the opening ceremony of SUBCON Thailand 2026 — the 20th edition of ASEAN’s largest industrial subcontracting and business matching event, co-organized by the BOI, Informa Markets Thailand, and the Thai Subcontracting Promotion Association.

In his opening remarks, Thai Deputy Prime Minister and Finance Minister Ekniti Nitithanprapas struck a note that captured the event’s evolved ambition. This was no longer simply a parts sourcing show. Thailand’s manufacturers, he said, must move from being built-to-order parts suppliers to becoming industry solution co-creators and global corporate partners — a higher-value role that demands design capability, quality systems, and the confidence to compete internationally.

“SUBCON Thailand is a mechanism the BOI uses to put Thai entrepreneurs at the center of global supply chains — and to keep them there. The world is going through the biggest industrial shift in a generation.” — Narit Therdsteerasukdi, Secretary-General, Thailand BOI

Standing next to them was the US-ASEAN Business Council, which has formed a semiconductor working group to help Thai SMEs qualify for global supply chains. Their message: “Thailand is no longer just an alternative to China – it’s a primary destination for IC backend.”

Lumentum, benchmark and the US-ASEAN business council
Of all the company visits on this trip, the one at Lumentum International (Thailand) in Nava Nakorn Industrial Estate, Pathum Thani, felt the most like a glimpse of where Thailand wants to go — not just where it is. Lumentum has been operating here since 2017, initially as an assembly and testing base for chips used in communications and telecommunications. Nine years later, the facility employs more than 6,000 workers, including over 700 engineers and scientists trained in photonics technology — a depth of local expertise that is genuinely rare in Southeast Asia.

I saw photonics chip assembly for 800G optical transceivers – cutting-edge work that requires submicron alignment. Their GM told me they chose Thailand because of BOI’s supply chain incentives and the talent pipeline from MUT.

In 2024, exports from the Thai plant exceeded 14 billion baht, with output forecast to more than double in 2025. The most recent BOI-approved expansion — a new investment of more than 2.3 billion baht — is producing ultra-high-power chip-on-carrier light-emitting chips destined for AI processors (GPUs), laser-based medical devices, and intelligent vehicle systems. These are not commodity components. They are precision photonics devices at the frontier of AI infrastructure.

Benchmark Electronics represents a different dimension of Thailand’s electronics ecosystem — the electronics manufacturing services (EMS) layer that sits between component suppliers and OEM brands. With operations anchored in Thailand, as highlighted by Ken Hendrickson Vice President Quality / Engineering-Asia, Benchmark brings sophisticated contract manufacturing capabilities to complex, high-mix, low-to-medium-volume production: the kind of work that demands engineering flexibility, quality systems, and deep customer partnership rather than brute-force volume.

At its Thai facility, Benchmark handles production for customers in industrial, medical, aerospace and defence, and advanced computing sectors. These are the most demanding EMS programs in existence traceability requirements, regulatory qualifications, and customer specifications that leave no margin for error. For Thailand’s semiconductor supply chain narrative, Benchmark matters because it represents the integration capability that transforms components into systems the value-add layer that moves a country up the industrial sophistication curve.

My final formal engagement of the week was a roundtable convened with the US-ASEAN Business Council Praab Pianskool, Chief Representative at US- ASEAN Business Council a forum that put the industrial visits of the preceding days into sharper geopolitical relief. The Council brings together American companies with stakes across ASEAN, and in 2026, with global supply chains still rebalancing in the wake of tariff uncertainty and US-China technology tensions, Thailand’s position as a trusted, US-aligned manufacturing destination has never been more commercially relevant.

They’re facilitating something rare: a trilateral working group involving US chip designers, Thai OSATs, and Malaysian wafer fabs.

A nation positioning for the long game

What emerged from this tour was not simply a collection of isolated projects or investment announcements.

Thailand is attempting something much larger: the coordinated construction of a national semiconductor ecosystem.

The ingredients are increasingly visible — government coordination, industrial infrastructure, multinational participation, academic engagement, engineering development, and long-term policy planning.

Challenges certainly remain. Competition across Southeast Asia is fierce, particularly from Malaysia, Vietnam, and Singapore. Advanced wafer fabrication remains extraordinarily capital-intensive. Talent development must scale rapidly.

Yet Thailand’s approach appears notably grounded in realism. Rather than chasing headlines, the country is leveraging existing manufacturing strengths while steadily climbing the semiconductor value chain.

For the global semiconductor industry, Thailand is no longer merely an electronics manufacturing destination.

It is becoming a strategic player worth watching.
