Publication number: 20240120317Abstract: A fan-out semiconductor device includes stacked semiconductor dies having die bond pads arranged in columns exposed at a sidewall of the stacked semiconductor dies. The stacked dies are encapsulated in a photo imageable dielectric (PID) material, which is developed to form through-hole cavities that expose the columns of bond pads of each die at the sidewall. The through-hole cavities are plated or filled with an electrical conductor to form conductive through-holes coupling die bond pads within the columns to each other.Type: ApplicationFiled: July 13, 2023Publication date: April 11, 2024Applicant: Western Digital Technologies, Inc.Inventors: Cheng-Hsiung Yang, Chien Te Chen, Cong Zhang, Ching-Chuan Hsieh, Yu-Ying Tan, Juan Zhou, Ai-wen Wang, Yih-Fran Lee, Yu-Wen Huang
