Patent ID: 6995412

Claim:
An integrated circuit chip, comprising a first nominal-voltage decoupling capacitor and a second high-voltage decoupling capacitor, respectively comprising: a first Fin structure having a first thickness and a second Fin structure having a second thickness greeter than said first thickness, said first Fin structure and said second Fin structure each having a top surface and a first side surface opposite a second side surface, said first thickness being a distance between the first and second side surfaces of the first Fin structure, said second thickness being a distance between the first and second side surfaces of the second Fin structure, said first Fin structure including a single-crystal semiconductor material, said second Fin structure including the single-crystal semiconductor material; a first insulator structure adjacent the top surface, the first side surface, and the second side surface of the first Fin structure, thereby encapsulating the first Fin structure, and a second insulator structure adjacent the top surface of the second Fin structure; and a first conductor structure adjacent the first insulator structure, and a second conductor structure adjacent the second insulator structure, wherein the second conductor structure partially but not totally overlays the second Fin structure and a thickness of the second conductor structure is within a thickness of the second Fin structure, and wherein the first conductor structure totally overlays the first Fin structure and a thickness of the first Fin structure is within a thickness of the first conductor structure, said thickness of the first conductor structure being oriented in a sonic direction as said thickness of the first Fin structure, said thickness of the second conductor structure being oriented in a same direction as said thickness of the second Fin structure, said first insulator structure comprising a single insulative material distributed from the top surface of the first Fin structure to a bottom surface of the first conductor structure, said second insulator structure comprising a single insulative material distributed from the top surface of the second Fin structure to a bottom surface of the second conductor structure.
