CMOS sensor manufacturer

There are many manufacturers investing in CMOS R&D and manufacturing, including more than 30 in the United States, 7 in Europe, about 8 in Japan, 8 in Korea 1 and 8 in Taiwan Province Province. The leading manufacturer in the world is Agilent (Hewlett-Packard), with a market share of 565,438+0%, ST (Very Large Scale Integrated Circuit Vision) of 65,438+06%, Omni Vision of 65,438+03%, Hyundai of 8% and Photobit of about 5%, with a total market share of 93%. Sony is the world's largest manufacturer of CCD sensors and the first company to invest in 65,438+02-inch wafers and launch a 6-megapixel CCD. About 30-40% of Sony's CCD sensors are used by its own brand products, while others are sold to Canon, Sanyo, Casio, Hong Xin, Preil and Quanxun in Taiwan Province Province (merged with Canon in Taiwan Province Province).

Sony's product technical blueprint shows that in 2003, no other micro-products came out except the 8-megapixel ICX 456. The product size will maintain the current level, and instead, it will strengthen the camera function and support progressive scanning, such as ICX455/465 with 5 million pixels, ICX45 1/48 1, ICX46 1 with 3.3 million pixels.

Most of the market of high-end products is still occupied by Sony, and the market is still in short supply, so the company is in no hurry to reduce costs. However, once Sony's most advanced technology (pixel size 2.6~2.8mm) reaches the mature stage (the yield exceeds 50%), the company is bound to further apply this technology to other products (at present, only11.8 OmniVision was established in 1995 (hereinafter referred to as OV). In June 2002, OmniVision took the lead in introducing OV 2 10 with 265438+ megapixels, which shocked the market. Although there are not many mass-produced products using this sensor at present, it shows that CMOS sensors can begin to enter the middle and high-end digital camera market originally belonging to CCD sensors. According to the data, Taiwanese businessmen such as Tianhan, Ming and Hongyou have started to adopt OV26 10 of the company. Looking forward to 2003, OV will launch products with 3.3 million pixels and 1/2 inches between1quarter and second quarter, and adopt TSMC 0. 18mm process to expand the application scope of CMOS sensors again. In the mobile phone market, the camera module of CMOS module has become the product with the largest number of mobile communication applications.

In terms of low-power products, OV also introduced the V7640 of 12 in 2002, which can run in the 2.5V environment and is the chip with the lowest power consumption among VGA products at present. As for the newly planned products in 2003, OV plans to launch 1.3 megapixel, 1/4 inch, VGA and 1/7 inch in the second half of the year, hoping to seize the market opportunity before CCD manufacturers launch 1.3 megapixel low-power products. Sanyo is the most distinctive one. The company is committed to improving the power consumption of CCD sensors, and its main application target is camera phones. The Sharp J-SHxx series first launched by J-Phone uses Sanyo's CIF CCD sensor, and mobile phone manufacturers such as Sharp and Toshiba also plan to launch Sanyo's VGA products from the fourth quarter of 2002 to the 2003 1 quarter. The product planning of Panasonic and Sharp is similar to that of Sony. The main difference is that Panasonic will launch smaller products with 4 million pixels (1/2.7 inches) and 1.3 million pixels (1/4 inches).
