Patent ID: 8592875

Claim:
A semiconductor gas sensor comprising: a semiconductor body having a passivation layer formed on a surface of the semiconductor body; a gas-sensitive control electrode separated from a channel region by a gap and implemented as a Suspended Gate Field Effect Transistor or the control electrode being arranged as a first plate of a capacitor with a gap, and a second plate of the capacitor being connectable to a gate of the field effect transistor implemented as a Capacitively Controlled Field Effect Transistor, the control electrode having a semiconductor substrate layer with an overlying adhesive layer and a gas-sensitive layer overlying the adhesive layer, the control electrode being connectable to a reference voltage, and the surface of the gas-sensitive layer facing the channel region or the second plate; a support area having a first support structure with a first bearing region, and having a second support structure with a second bearing region; and a contact area formed on the surface of the semiconductor body, wherein the support area adjoins the contact area, wherein the contact area has a first contact region and a second contact region, the first contact region comprising a first formation passing through the passivation layer, wherein the first formation has a bottom surface with a conductive layer connectable to the reference voltage, wherein the first contact region has a frictional connection and an electrical connection with the control electrode via a first connecting component, wherein the second contact region has at least a frictional connection with the control electrode via a second connecting component, and wherein the first connecting component at least partially fills the formation and connects the control electrode to the conductive layer.
