Patent ID: 11875992
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 12:
13. A semiconductor device comprising:
a substrate;
a lower electrode on the substrate, the lower electrode including a first portion and a second portion that is on the first portion;
a support pattern arranged adjacent to the second portion of the lower electrode;

a dielectric layer on the lower electrode; and
an upper electrode on the dielectric layer,
wherein the first portion of the lower electrode includes a first lower electrode pattern and a second lower electrode pattern that is on the first lower electrode pattern,
wherein the second portion of the lower electrode includes a third lower electrode pattern,
wherein the first lower electrode pattern of the first portion of the lower electrode is the same material as that of the third lower electrode pattern of the second portion of the lower electrode,
wherein the third lower electrode pattern of the second portion of the lower electrode contacts the support pattern,
wherein the first lower electrode pattern of the first portion of the lower electrode is spaced apart from the support pattern, and
wherein a width of the first portion of the lower electrode in a direction that is parallel to a top surface of the substrate is greater than a width of the second portion of the lower electrode in the direction.
