Patent ID: 11908807
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device comprising:
a substrate comprising first-conductivity-type impurities;
a first active region and a second active region provided on the substrate;
a first deep element isolation layer surrounding the first active region;
a second deep element isolation layer surrounding the second active region;
a suction region surrounding the first deep element isolation layer and the second deep element isolation layer, the suction region comprising the first-conductivity-type impurities;
a well region provided in the substrate between the first active region and the second active region, the well region comprising second-conductivity-type impurities different from the first-conductivity-type impurities;
a shallow element isolation layer provided between the suction region and the well region; and
a guard structure connected to the suction region,
wherein the substrate comprises a signal path portion that is provided between a top surface of the substrate and the well region, and surrounds an upper portion of the well region.
