Linton Crystal Technologies Uses AI To Detect Crystal Structure Loss, Notify Operator

News

In its first use of AI techniques to manage crystal control processes, Linton Crystal Technologies has developed an early warning system for when crystal structure loss is likely. This is the company's latest upgrade to its Kayex Intelligent Crystal Control System (KICCS) for its Czochralski (CZ) process crystal growers.

“With one operator overseeing many CZ growers at once, it's not likely that structure loss will be detected immediately, or even in a timely manner. This results in a lot of wasted time, energy and material devoted to pulling a dead crystal,” explains Jeromy Tompkins, senior software engineer with Linton. “This upgrade essentially makes the machines smarter, so they can alert the operator when it seems the crystal has lost structure. The operator then has the ability to make an informed decision as to whether or not to stop the growing process early.”

The automatic facet detection feature uses the KrystalVision application within KICCS to draw data from real-time furnace images. Advanced techniques are used to analyze the stream, evaluating the statistical probability of structure loss based on facet presence and location. If structure loss is predicted, an alarm is sent to the operator's control panel.

“In developing the update, we implemented algorithms for facet detection using traditional image processing and it worked well. However, the AI approach added an ability to locate facets that was unrivaled by the traditional approach,” says Tompkins. “I think this is a big step forward in facet detection and we also now have traction in AI, so we can make advancements with it fairly rapidly using the data we've collected.”

Linton recently hired Yiliang Shi, software engineer, to support the company's advancements in machine learning and automation. This was the first project she worked on since joining the company. “We were all really excited to see the results of this project and the power of AI to achieve what traditional algorithms struggle with,” she says. “There are so many opportunities going forward because we'll be able to draw upon both traditional and AI tools, based on the needs of the project.”

Automatic facet detection is among many upgrades Linton has planned for its control system; the company first introduced melt gap and power control upgrades.

Linton is the world leader in the design, development and manufacture of equipment for producing monocrystalline ingots for the solar, semiconductor and specialty materials industries. The company specializes in silicon and produces equipment for materials such as germanium and gallium arsenide. They also provide technical support, process engineering support and replacement parts to help clients get businesses off the ground, improve productivity and continue to innovate.



AngelTech Live III: Watch the virtual event ON-DEMAND!

AngelTech Live III was broadcast live on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and features online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

The event covered the whole spectrum of key developments affecting the compound semiconductor industry. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. This was considered a roadmap for this device, along with technologies for boosting its output.

With 3 interactive sessions over 1 day AngelTech Live III proved to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
