Patent number: 12154860Abstract: A method of forming a semiconductor device includes forming vertical contact fingers in a substrate having side portions that are flexible. Contact fingers are formed near one or more edges of the flexible side portions of the substrate. After semiconductor dies are mounted to and electrically coupled to the substrate, the semiconductor device may be encapsulated by placing the device in a mold chase including upper and lower mold plates. The lower mold plate is sized smaller than the substrate so that the flexible side portions of the substrate including the contact fingers fold vertically upward to fit within the mold.Type: GrantFiled: June 16, 2021Date of Patent: November 26, 2024Assignee: Sandisk Technologies, Inc.Inventors: Zhongli Ji, Ning Ye, Chin-Tien Chiu, Fen Yu
