摘要:
A temperature sensing device and method for fabrication of the temperature sensing device are described that include a second temperature sensor disposed on and/or in the lid assembly. In an implementation, the temperature sensing device includes a substrate, a ceramic structure disposed on the substrate, a thermopile disposed on the substrate, a first temperature sensor disposed on the substrate, and a lid assembly disposed on the ceramic structure, where the lid assembly includes a base layer, a first filter layer disposed on a first side of the base layer, a first metal layer disposed on a second side of the base layer, a passivation layer disposed on the first metal layer, where the passivation layer includes at least one of a second metal layer, a via, a metal plate, or an epoxy ring, and a second temperature sensor disposed on and/or in the passivation layer.
