Patent ID: 11901319
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. A method of manufacturing a semiconductor device, the method comprising:
placing an encapsulant around a first semiconductor die and a protective layer, the encapsulant having a non-planar surface facing the protective layer and the first semiconductor die;
depositing a seed layer through the protective layer to be in physical contact with the first semiconductor die and extending over the encapsulant;
plating a conductive material onto the seed layer, the conductive material having a first portion over the encapsulant and a second portion within the protective layer;
forming a contact to the first portion of the conductive material;
forming an external connector to the contact; and
planarizing the encapsulant with the protective layer.
