Title: Dodd Defibaugh: Innovator in Semiconductor Technology
Introduction
Dodd Defibaugh is a notable inventor based in Camas, WA (US), recognized for his contributions to semiconductor technology. He holds a total of 5 patents, showcasing his innovative spirit and technical expertise in the field.
Latest Patents
Among his latest patents, Dodd has developed a method for the fabrication of trenches with multiple depths on the same substrate. This innovative approach allows for dual trench depths to be achieved on the same wafer by forming an initial trench that corresponds to the difference in final depths of the shallow and deep trenches. A second mask is utilized to open areas for the deep trenches over the preliminary trenches and for the shallow trenches at additional locations, enabling simultaneous etching of both shallow and deep trenches.
Another significant patent is the adjustable transmission phase shift mask. This phase shift mask features transmission properties that depend on the intensity of an incident light beam. The mask includes a substrate that is substantially transparent to the incident light beam, with a first phase shift layer that has a refractive index that is nonlinear with the intensity of the incident light beam. This innovation allows for the adjustment of properties such as interference patterns in the transmitted light beam by varying the intensity of the incident light beam, providing an additional tool for adjusting exposure patterns produced by the phase shift mask.
