Patent ID: 11948876
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A package structure, comprising:
a conductive structure having a first portion and a second portion, wherein the second portion is wider than the first portion;
a semiconductor chip laterally separated from the conductive structure;
a protective layer laterally surrounding the conductive structure and the semiconductor chip, wherein the first portion of the conductive structure has a sidewall extending from the second portion to a surface of the protective layer, the protective layer laterally surrounds an entirety of the sidewall of the first portion, the protective layer is a single layer, and the first portion and the second portion have different sidewall slopes; and
a redistribution structure electrically connected to conductive pads of the semiconductor chip, wherein the redistribution structure extends across an interface between the conductive structure and the protective layer.
