Publication number: 20240072090Abstract: Various embodiments of the present disclosure are directed towards a stacked complementary metal-oxide semiconductor (CMOS) image sensor in which a pixel sensor spans multiple integrated circuit (IC) chips and is devoid of a shallow trench isolation (STI) structure at a photodetector of the pixel sensor. The photodetector and a first transistor form a first portion of the pixel sensor at a first IC chip. A plurality of second transistors forms a second portion of the pixel sensor at a second IC chip. By omitting the STI structure at the photodetector, a doped well surrounding and demarcating the pixel sensor may have a lesser width than it would otherwise have. Hence, the doped well may consume less area of the photodetector. This, in turn, allows enhanced scaling down of the pixel sensor.Type: ApplicationFiled: January 5, 2023Publication date: February 29, 2024Inventors: Chi-Hsien Chung, Tzu-Jui Wang, Tzu-Hsuan Hsu, Chen-Jong Wang, Dun-Nian Yaung

Publication number: 20190148091Abstract: A luminous keyboard includes at least one key, a switch circuit board, a supporting plate, a backlight module, a reflecting plate and a light-sheltering plate. The backlight module emits a light beam. The backlight module is arranged between the reflecting plate and the light-sheltering plate.
