Abstract:
Disclosed are integrated circuit structures each having a silicon germanium film incorporated as a local interconnect and/or an electrical contact. These integrated circuit structures provide improved local interconnects between devices and/or increased capacitance to devices without significantly increasing structure surface area or power requirements. Specifically, disclosed are integrated circuit structures that incorporate a silicon germanium film as one or more of the following features: as a local interconnect between devices; as an electrical contact to a device (e.g., a deep trench capacitor, a source/drain region of a transistor, etc.); as both an electrical contact to a deep trench capacitor and a local interconnect between the deep trench capacitor and another device; and as both an electrical contact to a deep trench capacitor and as a local interconnect between the deep trench capacitor and other devices.
