With a total of three patents to his name, he has demonstrated expertise and innovation, particularly in the area of self-aligning device fabrication.

Latest Patents

Lucas’s latest patents illustrate his prowess in semiconductor design and fabrication. One of his notable inventions is the "Fabrication of isolated regions for use in self-aligning device process." This innovation involves the use of V-shaped lateral dielectric isolation grooves that effectively divide a semiconductor layer into multiple regions. The approach ensures that the oxide layer above the polycrystalline material within the grooves is thicker than that of the field oxide layer on the semiconductor layer. This design prevents the formation of retrograde surface profiles and masks the polycrystalline material, facilitating self-aligned device fabrication.

Another significant patent is the "Method of fabricating surface contacts for buried layer into dielectric." In this invention, Lucas describes a process for creating low-resistance contact paths to selected buried layers within dielectrically isolated islands. This technique employs V-etching of selected island moats, non-selective diffusion of impurities, and a series of steps leading to the formation of devices on the substrate’s opposite surface.
