Title: Innovations by James Pan in Semiconductor Technology

Introduction

James Pan is a prominent inventor based in Colorado Springs, CO (US). He has made significant contributions to the field of semiconductor technology, holding a total of 14 patents. His work primarily focuses on methods that enhance the formation of polysilicon films and integrated circuits.

Latest Patents

Among his latest patents, one notable invention is the method of forming hemispherical grain (HSG) layers and devices. This process involves flowing chlorine during the formation of a polysilicon film, which acts as an etchant to insulative areas adjacent to polysilicon structures. This innovative approach allows for the creation of bottom electrodes for capacitors, followed by an anneal to produce HSG polysilicon. Additionally, multilayer capacitor containers are formed in a non-oxidizing environment, ensuring that no oxide is created between the layers. The resulting structure is planarized to create separate containers made from doped and undoped amorphous silicon layers. Selected undoped layers are then seeded in a chlorine-containing environment and annealed to form HSG. A dielectric layer and a second electrode are subsequently formed to complete the cell capacitor.

Another significant patent involves forming integrated circuits using selective deposition of undoped silicon film seeded in chlorine and hydride gas. This method also utilizes chlorine during the formation of the polysilicon film, enhancing selectivity and allowing for the creation of bottom electrodes for capacitors. The process is similar to the previous patent, emphasizing the importance of chlorine in achieving desired results in semiconductor fabrication.
