Patent ID: 7268351

Claim:
A gas sensor module for a spectroscopic measurement of at least one gas concentration, comprising: a spectroscopic gas sensor having a sensor chip which has a micropatterned measuring structure and contact pads, and having an IR-transparent cap chip which is attached to the sensor chip and covers the measuring structure; a premolded package, injection-molded from one of a plastic material and a molding compound and having a package bottom and a package edge to which a cover, having a screen opening situated above the measuring structure, is attached; a filter chip situated between the cover and the cap chip for selectively filtering an infrared spectral range; and a lead frame which is partially injected into the premolded package and has multiple leads whose outer areas are connecting pins for contacting a substrate and whose inner areas are contact pads which are contacted with the contact pads of the gas sensor, the connecting pins being bent upward from the package edge.
