IPC: H01L31/14
Filed: 1998-08-12
Abstract: PURPOSE: When a thermal video semiconductor element, a super-conductive detecting element and an accumulated element with a single crystal structure are placed closely, it is very hard to send signals due to serious thermal noise of the super-conductive detecting element in ball bonding or wire bonding. This device is to provide the thermal video element that minimizes thermal noise. CONSTITUTION: There is the first metal electrode(112) formed on a signal controlling semiconductor element(111) and an insulating film(113) on top of it. There is a mesa shaped heat shield film(114) to avoid the effects of thermal noise to a heat detecting part between the second electrode(115) and the insulating film(113). A part of the insulating film(115) is opened to the second metal electrode and the second metal electrode(115) is connected with the first metal electrode(112) electrically. The heat detecting part comprises a heat detecting element(121) and the third metal electrode (122). A ball bonds the signal controlling semiconductor element(111) and the heat detecting part. In the mean time the heat shield film(114) is formed with insulating resin. Thus the signal controlling semiconductor element(111) minimizes the transmission of heat noise and simplifies the signal controlling circuit.
