Semiconductor devices with reduced active region defectcs and unique contacting schemes

摘要

There is disclosed a surface-illuminated photodetector and a method of making such. There is provided an array of active region semiconductor pixels. There is provided separated, opposite-conductivity-type contacting regions within each pixel. There is provided metal contacts to the contacting regions so that within each pixel the metal contacts cover at least about 30% of the top surface area of the aggregate of the contacting regions.
