Patent ID: 11923355
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. A semiconductor device comprising:
a transistor structure comprising:
a base;
a first terminal formed within the base; and
a second terminal formed within the base, wherein the first terminal and the second terminal are formed by doping the base; and

a deep trench capacitor structure comprising:
a first metallic electrode layer; and
a second metallic electrode layer, wherein the first terminal is electrically connected to the first metallic electrode layer, and wherein the second terminal is electrically connected to the second metallic electrode layer, wherein a voltage breakdown value between the first terminal and the second terminal is less than a voltage breakdown value between the first metallic electrode layer and the second metallic electrode layer.
