Introduction

Andrew C. Campbell is a notable inventor based in Austin, Texas, recognized for his significant contributions to semiconductor technology. With a total of four patents to his name, Campbell has made strides in the field of electronics, particularly in the development of methods for fabricating semiconductor structures and capacitors.

Latest Patents

One of Campbell's latest patents focuses on methods for fabricating semiconductor structures. This innovative process involves depositing a first layer onto a substrate, followed by a second layer. A plurality of line structures is then etched into the second layer. Subsequently, a third layer is deposited onto these line structures and etched to expose them. The method allows for the removal of the line structures, leaving an etched third layer that can be used as a mask to etch the first layer, ultimately forming a semiconductor structure. Additionally, the methods may include steps for etching the substrate and annealing it to create a corrugated surface.

Another significant patent involves a capacitor with a metal-oxide dielectric layer. This capacitor is designed with an upper electrode layer that connects electrically to an underlying circuit element. It is particularly useful in forming storage capacitors for DRAM and NVRAM cells. The process includes forming an opening through the capacitor to the circuit element, creating an insulating spacer, and establishing a conductive member that connects the circuit element to the upper electrode layer.
