DEFINITION

Classification: 257/444

Light sensor elements overlie active switching elements in integrated circuit (e.g., where the sensor elements are deposited on an integrated circuit):

(under subclass 443) Subject matter wherein the active switching elements are in a monolithic chip which is combined with an array of light responsive elements which overlie the former.
