In partnership with Chinese foundry Semiconductor Manufacturing International Corp. (SMIC), Shanghai-based start-up group Cista System Corp. started mass production of two CMOS image sensors (CIS).

Undergoing mass production are the 1.3Mpx and 8Mpx CIS, which measure 1.75?m pixel and 1.4?m pixel, respectively. Both sensors feature back-side illumination (BSI) and are based on SMIC's 0.13?m BSI technology platform.

Based on a low leakage process, SMIC's BSI process only uses three aluminium metal layers for reduced cost and supports pixel sizes down to 1.4?m for 8Mpx-resolution CIS. SMIC also provides full in-house turn-key service, which includes CIS wafer fabrication, colour filter and microlens processing, TSV-CSP and testing to help customers shorten the supply chain with fast cycle time and low cost.

"Through working with our partner, Cista System Corp., we are very pleased with the achievement of the production phase for BSI technology," said Shiuh-Wuu Lee, executive vice president of technology development of SMIC. "Tests on the two sensors have shown great performance, which demonstrates our readiness in 0.13?m BSI technology platform. SMIC is also developing 1.1?m pixel BSI for 13-megapixel resolution and above and 3D stacked BSI for high-end applications. With these new sets of products, we hope to provide high-quality CMOS image sensors to our customers at a competitive price."

Cista CEO Wilson Du said, "As we move forward, we hope to see more of our designs used in wider applications such as consumer electronics, telecommunications, medical equipment, automotive industry, automation and other applications."
