Title: Innovations of Jie Bai in Semiconductor Technology

Introduction

Jie Bai is a prominent inventor based in Bedford, NH (US), known for his significant contributions to semiconductor technology. With a total of seven patents to his name, he has made remarkable advancements in the field, particularly in the formation of devices such as solar cells.

Latest Patents

One of Jie Bai's latest patents focuses on the formation of devices by epitaxial layer overgrowth. This method provides innovative structures for creating devices on substrates that include lattice-mismatched materials. The process involves forming an opening in a masking layer over a substrate containing a first semiconductor material. A first layer of a second semiconductor material, which is lattice-mismatched to the first, is formed within this opening. This first layer extends above the top surface of the masking layer. Subsequently, a second layer of the same second semiconductor material is formed on the first layer and over part of the masking layer. The invention emphasizes a vertical growth rate of the first layer that exceeds its lateral growth rate, while the lateral growth rate of the second layer surpasses its vertical growth rate. Another notable patent addresses defect reduction using aspect ratio trapping, which involves lattice-mismatched epitaxial films formed near non-crystalline sidewalls. This invention includes facets that direct dislocations in the films toward the sidewalls, enhancing the quality of the semiconductor materials.
