Well Corporation, whose full name is Shanghai Well Semiconductor Corporation, was registered on May 15, 2007 at the Shanghai Administration for Industry and Commerce.
WELL is a globally ranked Chinese semiconductor design company, and on May 4, 2017, it was successfully listed on the Shanghai Stock Exchange. Weir is one of the few domestic companies with both semiconductor R&D and design and semiconductor distribution capabilities, and owns three brands: Howell Technologies, Weir Semiconductor and Spectrum.
Well's semiconductor product design business consists of three major business systems: image sensor solutions, touch and display solutions, and analog solutions, and as a globally recognized chip design company providing advanced digital imaging solutions.
Products have been widely used in consumer electronics and industrial applications, including smartphones, tablets, laptops, webcams, security surveillance devices, digital cameras, automotive and medical imaging.
Advantages of Weir's main products:
The company's main product is the OV60A. As the world's first 0.61-micron-pixel, high-resolution CMOS image sensor, the OV60A offers 60-megapixel resolution with a pixel size of just 0.61 microns, the smallest in its class. The OV60A is available in a 1/2.8-inch optical format with aspect ratio configurations of 4:3 or 16:9.
The four-in-one color filter array on the OV60A outputs up to 15 megapixels using near-pixel merging to output up to 15 megapixels with four times the sensitivity, providing 1.22-micron-equivalent performance for previews and native 4K video, with the electronic image stabilization (EIS) additional pixels required.
The sensor also supports a low-power mode for "always-on" sensing, which saves valuable battery life when used in conjunction with the phone's artificial intelligence features. To increase resolution while reducing pixel size and optical format, the OV60A utilizes Howell's Pure Cel Plus-S wafer stacking technology.
