Title: Innovations of Hui-Wen Shen in Semiconductor Technology

Introduction

Hui-Wen Shen is a prominent inventor based in Kaohsiung, Taiwan. He has made significant contributions to the field of semiconductor technology, particularly in the development of 3D integrated circuits (3DIC). With a total of 2 patents, his work focuses on improving hybrid bonding methods for semiconductor wafers.

Latest Patents

Hui-Wen Shen's latest patents include innovative methods for enhancing hybrid bond yield in semiconductor wafers that form 3DIC devices. These methods involve the use of first and second wafers with dummy and main metal deposited and patterned during back-end-of-line (BEOL) processing. The dummy metal pattern occupies between 40% to 90% of the surface area of any given region, which allows for improved planarization of wafer surfaces. This high dummy metal surface coverage, combined with slotted conductive pads, results in wafers that exhibit minimal topographic differentials, with step height differences of less than 400 micrometers. The planarized wafers are aligned and hybrid bonded using heat and pressure, ensuring dielectric-to-dielectric and RDL-to-RDL bonding. Lithography controls are employed to achieve wafer edge topographic uniformity, promoting improved bond uniformity for the resulting 3DIC devices.
