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

Claim 8:
9. 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 suction region surrounding the first active region and the second active region, the suction region comprising the first-conductivity-type impurities; and
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,
wherein the well region is spaced apart from a top surface of the substrate and the suction region, and
wherein a minimum distance between the well region and the top surface of the substrate is smaller than a width of the suction region along a first direction parallel to the top surface of the substrate.
