More on CMOS image sensors
The flow of information on CMOS image sensors continues unabated. More and more companies are introducing CMOS devices with enhanced specifications and technologies as cost-effective replacements for competing CCD sensors. These devices are anticipated to result in camera-on-a-chip designs for high-end, digital still and video cameras and scanners.
For example, UMC (Sunnyvale, CA; www.umc.com), a semiconductor foundry that operates seven wafer fabs in Japan and Taiwan, has disclosed a proprietary 0.18-µm-process CMOS sensor that is based on a generic mixed-mode process. This process demonstrates a "3 in 1" integration, which combines an analog-to-digital converter, digital image processor, and an imaging sensor on a single chip. It has the potential to produce pixel sizes as small as 3 µm and resolutions greater than 5 Mpixels.
Says Jim Ballingall, UMC vice president of worldwide marketing, "The transition from CCD to UMC CMOS is further facilitated in that changes in optics are not necessary due to smaller pixel sizes. Offerings in advanced-logic, mixed-signal, and microdisplay technologies enable a complete digital camera solution."
Adds Sabrina Kemeny, chief executive officer of Photobit Corp. (Pasadena, CA: www.photobit.com), a supplier of CMOS image sensors, "We look forward to continuing our long-term relationship with UMC as it continues to deliver the quality image-sensor technology we need for development of our camera on a chip."
Derek Cheung, vice president of research and director of the Rockwell Science Center (Thousand Oaks, CA; www.risc.rockwell. com), says, "We committed to UMC's 0.25-µm CMOS image-sensor process technology for developing our CMOS imaging-system-on-a-chip for high-performance video cameras. We look forward to migrating to UMC's 0.18-µm process and achieving greater performance."
Another developer of low-power CMOS imagers and intelligent cameras, SMaL Camera Technologies Inc. (Cambridge, MA; www.smalcamera.com), has unveiled its SCT-00VC single-chip CMOS image sensor that features the company's Autobrite technology. This technology allows the imager to adjust its dynamic range and provide quality images of scenes that are bright enough to saturate other standard imagers. Says Charles G. Sodini, company president, "Our imager is based on a proprietary brightness-adaptive pixel. Coupled with our proprietary algorithms, the imager permits the design of cameras that adapt to a variety of lighting conditions. The Autobrite technology captures the dark details of a scene while ensuring that the bright regions never saturate. In addition to this advantage, the VGA imager consumes just 30 mW at 60 frames/s."
Harry S. Lee, company vice president of technology, adds, "Coupled with our imager design is an optics design that allows us to build an extremely thin camera. For example, we are featuring our CMOS imager in a 0.2-in.-thin digital still camera called the Ultra-Pocket camera."
The SCT-00VC's VGA imager is a 642 x 482-pixel array in a 1/3-in. format. It provides low fixed-pattern noise and a variable frame rate up to 60 frames/s for capturing still or full-motion video. Available in color or monochrome, it also features on-chip programmable digital gain, correlated double sampling, timing, and 12-bit analog-to-digital converters.
Yet another image-sensor developer, Motorola Semiconductor Products Sector (Austin, TX; e-bus.mot-sps.com), has released its MCM20027 1280 x 1024-pixel, SXGA progressive scan image sensor, manufactured using Motorola's ImageMOS wafer process along with pixel design and patented pinned photodiode technology from Kodak and Motorola. It consumes less than 250 mW of power and includes correlated double sampling, programmable gain amplifier, analog-to-digital converter, and light sensitivity to 3 lux at 10 frames/s. The sensor outputs 10-bit Bayer-encoded RGB data.
