Tower Technologies Result in Superior Sensor Capabilities for Camera-Enabled Devices HSINCHU, Taiwan & MIGDAL HAEMEK, Israel--Nov. 1, 2005
--Tower Semiconductor, Ltd., a pure-play independent specialty wafer foundry, and Biomorphic Microsystems Corporation, a supplier of innovative imaging solutions for the cell phone and PDA markets, today announced that Tower has begun manufacturing of Biomorphic 2.0 and 1.3-megapixel CMOS image sensors.
Biomorphic has already won one of the five leading global cell phone manufacturers for one of these new products, which responds to the increasing demand for higher image quality on small mobile handsets. Japanese market research firm Techno Systems Research (TSR) estimates the 2006 total market for 2.0-megapixel CMOS modules to be 65 million units, while the 1.3-megapixel market is estimated at 190 million units.
The Bi8910T 1.3-megapixel and Bi8921T 2.0-megapixel SoC image sensors are produced in 0.18-micron process at Tower's Fab2, utilizing Tower's pixel IP and the company's optically-optimized multilayer metallization (OptiMuM(TM)), which achieves dramatically better optical sensitivity by reducing stack height from silicon to micro-lens.
Compared with other leading foundry IP, Tower's pixel IP provides:
- 70 percent higher sensitivity
- 50 percent less pixel defect density
- 70 percent lower dark current level
"With Tower's 0.18-micron process and pixel IP, we achieved excellent sensor performance," said Bimal Mathur, Senior Vice President and Chief Technical Officer of Biomorphic Microsystems. "Pixel performance was key in our ability to win a leading customer design. We were also very pleased with Tower's intimate customer support through design and ramp to production, contributing to our fast time-to-market."
"We are glad to complement Biomorphic's expertise in image solutions with our advanced pixel IP and process offering to bring superior yet low-cost image sensors to market that handset manufacturers need today," said Dr. Avi Strum, General Manager of CIS and NVM product line at Tower. "Biomorphic's swift penetration to a tier one cell phone maker with these new products is the best testimony for the success of our joint work."
Biomorphic's Bi8921T is a highly affordable CMOS color image sensor that debuts new technologies with an advanced 2 megapixel sensor. These include a color processing pipeline and JPEG compression in a single compact component. The Bi8921T offers UXGA resolution and is designed for cellular phone applications. It provides single-chip integration of a full suite of image processing functions to directly support viewfinder, still image, and video capture capabilities in today's latest mobile imaging platforms. Plus, with the addition of on-chip JPEG compression, full-size images can be captured with high readout speeds, yet low data transfer rates. With an embedded thumbnail image in the JPEG stream, the host processor need not decompress the full image for review. The Bi8921T provides superb image quality, ease of integration, compact size, and low power consumption for outstanding overall performance.
The Bi8910T offers SXGA resolution and is designed for cellular phone applications. Our highly advanced sensor design provides single-chip integration of a full suite of image processing functions to directly support viewfinder, still image, and video capture capabilities in today's latest mobile imaging platforms. The Bi8910T provides superb image quality, ease of integration, compact size, and low power consumption for outstanding overall performance.
Price and Availability
Both products are now in mass production. Bi8921T and Bi8910T are priced $6 and $3.5 per unit for large volumes, respectively.
