Visible light communication is a wireless communication method modulating the light of visible LED. In this study, high sensitive photo-transistor array has been developed for the visible light identification (ID) using CMOS 0.35 mum process. The response sensitivity of photo-transistor is over 0.8 A/W. The photo-transistor is selected by the outer signal in order to separate the signals from multiple...
The integrated CMOS photo-transistor array has been developed for visible light 1D system. And the photo-transistor is selected by CCD image and C software in order to separate the signals from multiple light sources.
We developed a new bulk strained Si/SiGe CMOS technology free from any Ge-related problems, which has a 90- to 110-nm strained Si layer thicker than the limit at which misfit dislocations occur and a new shallow-trench isolation (STI) structure that has a selective-epitaxial-Si (SES) layer to cover up the SiGe trench surface. This technology has advantages in process compatibility with Si CMOS because...
