Title: Innovations by Wei-Chih Lai: A Pioneer in Integrated Circuit Technology

Introduction

Wei-Chih Lai is a prominent inventor based in Changhua County, Taiwan. He has made significant contributions to the field of semiconductor technology, holding a total of 12 patents. His work focuses on innovative methods for forming integrated circuit packages and enhancing imaging tools.

Latest Patents

One of Wei-Chih Lai's latest patents is a method of forming an integrated circuit package that includes a padding layer on a carrier. This method involves several operations, such as placing a first semiconductor die on the padding layer and a second semiconductor die on the carrier. Both semiconductor dies are encapsulated with a first encapsulation layer, followed by the formation of a first redistribution layer structure. A third semiconductor die is then placed on this structure and encapsulated with a second encapsulation layer. The process concludes with the debonding of the carrier and the removal of the padding layer, resulting in a recess in the first encapsulation layer.

Another notable patent is the droplet generator and method of servicing an extreme ultraviolet imaging tool. This invention features a reservoir for molten metal and a nozzle that allows molten metal droplets to emerge. The design includes a gas inlet and an isolation valve to seal the nozzle from the ambient environment, ensuring precision in droplet generation.
