Title: Yu-Jen Chien: Innovator in Semiconductor Technology
Introduction
Yu-Jen Chien is a prominent inventor based in Taipei, Taiwan. He has made significant contributions to the field of semiconductor technology, holding a total of 13 patents. His work focuses on improving the efficiency and reliability of semiconductor manufacturing processes.
Latest Patents
One of Yu-Jen Chien's latest patents involves a semiconductor tool for copper deposition. This invention features a magnetic shield designed to reduce external noise in a chamber that includes a target and at least one electromagnet for copper physical vapor deposition (PVD). The shield's thickness ranges from approximately 0.1 mm to 10 mm, providing sufficient protection from radio frequency and other electromagnetic signals. As a result, copper atoms in the chamber experience less re-direction from external noise. This innovation ensures that even during hardware failures, such as electromagnet malfunctions or uneven wafer stages, the copper atoms remain less susceptible to small re-directions. Consequently, back end of line (BEOL) and middle end of line (MEOL) conductive structures are formed more uniformly, enhancing conductivity and improving the lifespan of electronic devices.
