Latest Patents

Liusuo Cheng holds a patent for a CMOS image sensor. This invention involves a unique design where a first dielectric layer is formed on a first surface of a semiconductor substrate. A plurality of lower microlenses, which have a bottom surface shaped like an arc concave structure, are positioned directly above the corresponding photodiodes within the first dielectric layer. Additionally, upper microlenses with a top surface shaped like an arc convex structure are formed above the lower microlenses. The materials used for the microlenses are carefully selected, with the refractive index of the upper microlens being greater than or equal to that of the lower microlens, while the lower microlens has a refractive index greater than that of the first dielectric layer. This innovative design enhances the performance of the CMOS image sensor.
