GalaxyCore Inc., a fabless image sensor company in China, has developed a technology called Through-Silicon-Illumination (TSI). According to the company, the technology targets image sensors with pixel sizes of 1.75um down to 1.1um and could be extended down to 0.9um pixels.

The technology brings several advantages: improved sensitivity and signal-noise ratio with reduced thermal noise, dark current and crosstalk; high-speed and low power, allowing higher frame rates; simpler and lower-cost manufacturing based on fewer process steps, detailed GalaxyCore.

The company said it expects to launch 5MP, 8MP and 13MP image sensor products using this technology in 2014 and 2015. It uses a 90nm logic process made for the company by Taiwan Semiconductor Manufacturing Co. Ltd (Hsinchu, Taiwan) and will begin volume production of sensors based on the technology shortly.

According to GalaxyCore CEO Zhao Lixin, their sensor line-up is primarily geared for the "fast-growing market of mobile devices such as smartphones and tablets."
