Patent ID: 11908924
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device, comprising:
a base substrate; and
a first thin-film transistor and a second thin-film transistor disposed on the base substrate,
wherein the first thin-film transistor comprises a first output electrode, a first semiconductor pattern including a crystalline semiconductor material, and a control electrode disposed on the first semiconductor pattern,
wherein the second thin-film transistor comprises an input electrode, a second output electrode, the control electrode, a second semiconductor pattern, which is disposed on the control electrode and including an oxide semiconductor material, and a conductive pattern, which is disposed on the second semiconductor pattern and exposes a portion of the second semiconductor pattern,
wherein the control electrode is disposed between the first semiconductor pattern and the second semiconductor pattern,
wherein the first semiconductor pattern, the control electrode, and the second semiconductor pattern are overlapped with each other, when viewed on a plane, and
wherein the conductive pattern passes through the second semiconductor pattern and contacts the first semiconductor pattern.
