Introduction

King L Hu is a notable inventor based in Torrance, CA, who has made significant contributions to the field of silicon technology. With a total of 3 patents to his name, he has developed innovative solutions that enhance the functionality of electronic devices.

Latest Patents

One of his latest patents is a Silicon Spatial Light Modulator. This device includes a silicon backplate with an insulating layer and a standoff grid of insulating material that defines an array of cells. Each cell has an electrode deposited on the backplate, and a thin membrane of doped silicon is mounted to the standoff grid. Mirrors are laid on the membrane to create an array of reflective pixels. The device operates by selectively charging the electrodes, causing the membrane to deflect and create a pattern corresponding to the electrical signals. Additionally, a vent hole is formed in each cell to assist in venting gas when the diaphragm is deflected, ensuring critical damping of the movement.

Another significant patent involves Planar Bipolar Transistors, which are constructed with a substrate and a collector layer that is epitaxially grown. The design includes an ion-implanted base layer and a further epitaxial layer that enhances the transistor's performance. The configuration allows for efficient electrical contact through the base, emitter, and collector ohmic contacts, optimizing the functionality of the transistor.
