Patent ID: 7388274

Claim:
A semiconductor structure comprising: an active layer; a device in said active layer; a first insulator layer, having a first side and a second side, said first side of said insulator layer adjacent said active layer; a bulk layer adjacent said second side of said first insulator layer; a second insulator layer adjacent said bulk layer; and a capacitor coupled to said device, said capacitor comprising: a capacitor plate comprising a portion of said bulk layer, said capacitor plate being positioned adjacent said second side of said first insulator layer in a region offset from said device; a capacitor dielectric comprising a portion of said second insulator layer adjacent said capacitor plate; and an isolated capacitor contact contacting said capacitor plate; wherein said capacitor contact is isolated by a deep trench isolation structure that extends to said second insulator layer and defines said portion of said bulk layer comprising said capacitor plate, wherein said semiconductor structure further comprises: a second bulk layer adjacent said second insulator layer, said second bulk layer comprising a second capacitor plate; and a second capacitor contact contacting said second capacitor plate, wherein said deep trench isolation structure and said capacitor dielectric insulate said capacitor plate from said second capacitor plate.
