Claim Text:
1. A semiconductor device comprising: a first substrate; a pixel over the first substrate, the pixel comprising: a second substrate over the pixel, wherein an insulating layer is over the transistor, wherein the photodiode and the MEMS element are over the insulating layer, wherein the photosensor portion is configured to detect light from an object contacting with a surface of the second substrate to determine a position and an area of a region where the object is contacting the surface of the second substrate, wherein the MEMS portion corresponding to the position of the region is configured to generate a force corresponding to the area of the region in a direction perpendicular to the first substrate and the second substrate to maintain a constant distance between the first substrate and the second substrate in response to a signal supplied from a processing circuit.
