Smartphone Electronic Technology Co., Ltd. officially launched the Cellphone Sensor (CS) Series mobile phone application image sensor products SC520CS and SC820CS. Both new products are built with 12-inch wafer process, equipped with SmartSens' innovative SFCPixel patented technology and ultra-low noise peripheral reading circuit technology. The platform has three key process technologies: wafer bonding technology, wafer thinning technology and silicon surface passivation technology, which can provide excellent imaging performance for the current smartphone front camera, rear main camera and rear auxiliary camera applications.
Smartphones are currently the largest application market for CIS products, and their imaging systems are constantly undergoing strong upgrades. According to Counterpoint Research, the CMOS image sensor (CIS) content of each smartphone will expand to an average of 4.1 in the future. At the same time, the combined effects of more powerful chipsets, breakthroughs in imaging performance, and advances in software and hardware will continue to provide consumers in the mobile phone market with a better imaging experience.
Innovative imaging technology and 12-inch wafer process achieve excellent imaging quality
The two new mobile phone applications released this time are equipped with SmartVision's innovative SFCPixel patented technology. The sensitivity of SC520CS and SC820CS can reach 840mV/lux·s, so that the mobile phone camera can have a low-light shooting environment. Excellent night vision imaging performance. At the same time, thanks to SmartVision's ultra-low noise peripheral reading circuit technology, both new products have excellent noise control performance. Taking SC820CS as an example, compared with products of the same specification in the industry, its read noise (RN) and fixed noise (FPN) are greatly reduced by 25% and 81% respectively, which can bring excellent night shooting imaging effects to mobile phone cameras. In terms of color rendering power, the Chroma high and low color temperatures of SC820CS have been increased by 13% and 22% respectively, making the image more vivid and the color more realistic.
In addition, the two new products are built with a 12-inch wafer process. Through the double improvement of area and chip utilization, the high yield rate of wafer chip output is greatly guaranteed. In view of the defects that are easy to occur during the processing process, products using 12-inch wafers have better reliability, and even if used in harsh environments such as high temperature and high humidity for a long time, they can maintain excellent imaging performance; On the one hand, thanks to the support of more advanced process technology, the 12-inch wafer can ensure the consistency of the performance of CIS products on the entire wafer to the greatest extent.
The first show of self-developed advanced BSI process platform products, three process technologies create excellent imaging quality
Compared with the traditional front-illuminated FSI, the back-illuminated BSI has better photosensitive performance, but because it is a highly customized technology, it has great technical difficulties in chip design and process. The SC520CS and SC820CS launched this time are the first batch of new products to be mass-produced by SmartVision's domestic self-developed advanced BSI process platform. The platform adopts three key technologies: wafer bonding technology, wafer thinning technology and silicon surface passivation technology. The process technology enables the product to have an excellent low-light imaging texture, which contributes to the high-quality demand for smartphone imaging nowadays.
Mr. Ouyang Jian, Deputy General Manager of Smartway, said: "The mobile phone CIS field is always carrying out product updates and performance upgrades. Only with the spirit of forging ahead and innovation can we better meet the dual growth needs of customers and the market. Smartway The two new mobile phone application products SC520CS and SC820CS launched this time are the first products of our self-developed advanced BSI process platform. and noise control performance. At the same time, with the support of SmartVision’s many cutting-edge imaging technologies, SC520CS and SC820CS have excellent low-light imaging quality, providing a high-quality video image experience for smartphone cameras.”
