Title: Discovering the Innovations of Inventor René A Lujan

Introduction

René A Lujan, an accomplished inventor based in Sunnyvale, California, has made significant contributions to the field of semiconductor technology. With two patents to his name, Lujan's work showcases innovative methods that enhance the efficiency and effectiveness of semiconductor devices.

Latest Patents

Lujan’s latest patents highlight his expertise in advanced fabrication techniques. The first patent, titled "Patterning using wax printing and lift off," describes a method for performing a liftoff operation. This method involves printing a liftoff pattern using low-resolution techniques, enabling the creation of fine feature patterns. Remarkably, the feature size is dictated by the spacing between printed patterns instead of the size of the printed patterns themselves. By carefully controlling the cross-sectional profile of the liftoff pattern, Lujan's approach allows for the formation of beneficial etch-mask aperture profiles, ultimately leading to diverging etched features through multi-layer printed patterns.

The second patent, "Method of fabrication of a support structure for a semiconductor device," outlines a sophisticated technique to fabricate semiconductor devices. In this patent, a starting substrate of adequate thickness with appropriate defect density is selected to avoid undesirable doping levels. A semiconductor layer with the required properties is then formed on this substrate. This approach enables the design of active components and electrical conductors with optimal doping levels, ensuring maximum wall plug efficiency (WPE). Importantly, the doping of the semiconductor layer can vary, with regions being doped at different levels, allowing for improved performance based on the specific thickness of the higher-doped material.
