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

Claim 10:
11. A method for forming a semiconductor device structure, comprising:
forming a semiconductor protruding structure over a substrate;
surrounding the semiconductor protruding structure with an insulating layer;
forming a dielectric layer over the insulating layer;
partially removing the dielectric layer and insulating layer using a planarization process such that topmost surfaces of the semiconductor protruding structure, the insulating layer, and the dielectric layer are substantially level with each other;
forming a protective layer to cover the topmost surfaces of the dielectric layer; and
recessing the insulating layer after the protective layer is formed such that the semiconductor protruding structure and a portion of the dielectric layer protrude from a top surface of a remaining portion of the insulating layer.
