Abstract
PURPOSE: To provide a semiconductor device in which malfunctions is prevented by mounting an alpha rays absorbing screen on a semiconductor element in adhesive contact to cover all of its active region.
CONSTITUTION: All over an active region 21 of a semiconductor element 2 including its circumferential region 5, a screen 4 composed of a thin piece of single crystal silicon 0.01mm or more thick is placed in adhesive contact with an about 1μm thick passivating film 22 composed of phosphor glass or the like as lying inbetween, thereby to absorb alpha rays and other radiation coming toward the active region 21. In this device, all alpha rays 61 coming toward the active region 21 from right above are absorbed by the screen 4 and all alpha rays 62 coming into at an angle with respect to the active region 21 do not reach the same region because of the screen 4 which is extended over the region 5, while all alpha rays 63 coming from right below are absorbed by the substrate 2 before reaching the region 21.
