Austriamicrosystems’ Full Service Foundry business has introduced a High Performance CMOS High Voltage process capable of operating at 50V. The initial device offering will have operation voltages of 20V and 50V, but the company believes that the process is capable of providing devices with operating voltages beyond 120V and breakdown voltages beyond 150V.

Austriamicrosystems' Full Service Foundry business has introduced a High Performance CMOS High Voltage process capable of operating at 50V. The initial device offering will have operation voltages of 20V and 50V, but the company believes that the process is capable of providing devices with operating voltages beyond 120V and breakdown voltages beyond 150V.

The process is a fully modular proprietary extension of austriamicrosystems' production proven 0.35micron CMOS technology licensed from TSMC enabling optimum reuse of low voltage CMOS IP. The purely CMOS based HV process is achieved with only 17 to 19 masks making for cost competitiveness. HV ICs are used in display drivers, consumer, computer, telecom, automotive and industrial control applications.

“Our new purely CMOS based 0.35micron high voltage technology enables customers for the first time in the industry to also address high performance/high current applications that were previously reserved for much more complex and costly processes such as BCD,” says Peter Gasteiner, senior vice president and general manger of the business unit. “With our new proprietary High Voltage device architecture we achieve on-resistance values at least equivalent to benchmark BCD processes at much lower process complexity.”

Design rules and target parameters are available already and by the beginning of next year design starts and engineering runs will be available. Fully qualified production runs will be on offer from Q2 2004. The devices will be produced on austriamicrosystems' 200mm SMIF wafer production lines.

The process features extensively characterised and modelled 20V and 50V CMOS-HV and bipolar devices. The technology comes with a full set of analogue modules, capacitors and a high resistive poly option. Full design support including digital, analogue and high-voltage libraries and peripheral cells with high driving capability are available as part of the mixed-signal high-voltage HIT-Kit.

AngelTech Live III: Join us on 12 April 2021!

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

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. 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. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove 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.
