Title: The Innovative Contributions of Bin Liu

Introduction

Bin Liu is a prominent inventor based in Taipei, Taiwan, known for his significant contributions to the field of semiconductor technology. With a total of six patents to his name, Liu has developed innovative methods that enhance the performance and efficiency of dynamic random access memory (DRAM) cells.

Latest Patents

One of Liu's latest patents is a method for planarizing DRAM cells. This method involves providing a silicon substrate with a field oxide layer, an oxide layer, and a capacitor formed thereon. The process includes forming a first dielectric layer over the substrate, etching back portions of this layer to create a spacer layer, and subsequently forming a second dielectric layer over the spacer. An insulating layer is then created over the second dielectric layer, which is fully etched back to form a third dielectric layer.

Another notable patent is the method of manufacturing a stacked capacitor with fin-shaped storage. This invention allows for the creation of stacked capacitors with fin-shaped electrodes that increase capacitance on DRAM cells. It eliminates the need for a silicon nitride etch stop layer, which can cause substrate stress and defects. The process involves fabricating capacitor bottom electrodes with fin-shaped portions by depositing a multilayer of silicon oxide and doped polysilicon on a partially completed DRAM device. The invention also includes a unique masking step to complete and electrically isolate the bottom fin-shaped electrodes.
