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

Claim 8:
9. A method comprising:
forming a device layer over a first substrate;
forming a first interconnect structure over the first substrate;
performing a low power plasma deposition to form a first dielectric layer over the first interconnect structure;
performing a high power plasma deposition to form a second dielectric layer over the first dielectric layer, the performing the high power plasma deposition comprising a plasma penetrating a portion of the first dielectric layer; and
attaching a second substrate to the second dielectric layer, the second substrate comprising a third dielectric layer disposed over a semiconductor substrate, and attaching the second substrate to the second dielectric layer comprises physically contacting the second dielectric layer to the third dielectric layer.
