OKI Implements Sarnoff's Takecharge® On-Chip ESD Protection In High-Voltage ICs

Design Approach for On-Chip ESD Protection Successfully Implemented in High-Voltage Chips

August 26, 2005 -- Oki Electric Industry Co., Ltd. (TSE: 6703) of Tokyo, Japan, has successfully produced ICs in 0.5um/43V, 0.35um/16.5V, and 0.25um/25V process technologies using TakeCharge® design technology from Sarnoff Europe of Gistel, Belgium. Sarnoff is a diversified technology & services company with a long history of semiconductor innovations.

"Under a technology transfer agreement, Oki has licensed silicon-proven TakeCharge® devices customized specifically for our high-voltage processes. Our goal is to ensure that we can consistently manufacture chips that perform at high voltages with full electrostatic discharge (ESD) and latch-up protection," said Mr. Shiratori, Deputy General Manager, Display Driver Division of Oki's Silicon Solution Company. "We have implemented these TakeCharge devices in our various high volume products, such as LCD and OLED driver devices, where they deliver substantial added value for Oki and its customers."

TakeCharge® technology is a design approach to on-chip ESD circuitry. It reduces the size of the I/O section on IC dies, while maintaining or improving on-chip protection against ESD. Implementing robust ESD protection devices is an important part of IC design.

"We're very pleased that an industry leader like Oki has chosen TakeCharge® for its new line of high-voltage ICs," said Koen Verhaege, Managing Director of Sarnoff's Integrated Circuit Systems & Services business unit and Executive Director of Sarnoff Europe. "Our technology is optimized for ESD protection and latch-up immunity in high-voltage applications, and we are proud of its consistently successful implementation in Oki's ICs."

"We look forward to working with Oki to ensure yet more successful implementations in a broad range of IC's."

In addition to significant die size reductions, TakeCharge® technology ensures "first time right" ESD design, according to Verhaege. With more dies on a wafer and less time spent in design and revisions, the technology has the potential to save millions of dollars in product development and production costs. It also helps eliminate the cost of additional mask sets.
