The Development of 65nm Embedded Flash Process

United Microelectronics Corporation was founded in 1980s as Taiwan’s first semiconductor company. It offers advanced technology and manufacturing services for applications in all the main sectors of IC industry.

The first working silicon on 65nm, which uses a silicon oxide nitride oxide silicon process, is developed by this company. This process supports the embedded flash memory. The development of 65nm embedded flash process is based on the cooperation of programmable chip firm Cypress Semiconductor and UMC. The embedded flash process will be applied in the next generation PSoC programmable system-on-chip products. After the agreement of these two companies has been reached, this technology will be applied widely in the future days.

The 65nm SONOS embedded non-volatile memory technology has integrated into UMC’s standard LL65 process. This technology is called S65. The expert maintained that the embedded NVM is the important characteristic of many IC designs. With the product which is called “minimum design disturbance to other silicon IPs”, the existing or new designs using the LL65 process will now be able to add embedded flash memory.

When compared with the 7-12 additional masks for other embedded flash technology approaches, the S65 process needs three more mask layer to a standard CMOS process.

“Using Cypress products as a reference, the new process is expected to provide a 75% reduction in array size and 50% power reduction compared to products manufactured on the current 130nm S8 process,” said the semiconductor foundry. "Our product lines are eager to introduce new, high-performance products on S65, and we look forward to working with UMC to license the technology to their large customer base,” said Shahin Sharifzadeh, executive v-p of worldwide manufacturing and operation for “We look forward to ramping this process to production for Cypress and other UMC customers,” said Yen.

This new product is planned to meet the foundry customers in the third quarter of 2011.
