Patent number: 6987223Abstract: A thermopile structure containing improved heat sinks for thermocouples in the detectors is described. The heat sinks are provided without additional processing. The heat sinks are added by using “dummy traces” to the polysilicon mask. The “dummy traces” act as heat sinks to transfer of thermal energy from the narrow metallic traces used in the thermocouple. The “dummy traces” are not electrically connected to the thermopile, therefore they do not affect the electrical resistance of the thermopile. Also, the “dummy trace” does not add significant mass to the thermopile/membrane system; therefore they do not adversely affect the thermal conductance of the system.Type: GrantFiled: August 28, 2002Date of Patent: January 17, 2006Assignee: Delphi Technologies, Inc.Inventor: Philip K. Schneider
