Title: Innovations of Harianto Wong

Introduction

Harianto Wong is a notable inventor based in Santa Clara, CA, with a remarkable portfolio of seven patents. His work primarily focuses on advancements in semiconductor technology, particularly in the fabrication of high-frequency capacitors.

Latest Patents

One of his latest patents is a method for fabricating a precision high-frequency capacitor formed on a semiconductor substrate. This innovative capacitor design involves doping the semiconductor substrate to achieve low resistivity. A second electrode, insulated from the first, is formed over the front side surface and can be connected by a metal-filled via to the back side surface. In some embodiments, the via may be omitted, allowing the second electrode to be in electrical contact with the substrate or to be formed on top of the dielectric layer, resulting in a pair of series-connected capacitors. To enhance the performance, electrostatic discharge (ESD) protection is provided by a pair of oppositely-directed diodes formed in the substrate, connected in parallel with the capacitor. This design increases capacitance while maintaining a low effective series resistance. The electrodes feature a plurality of interdigitated fingers, which are designed to optimize the capacitor's performance. The fabrication process is conducted at a wafer scale, allowing for the concurrent production of multiple capacitors, which are then separated using a dicing technique.
