Latest Patents

Eldridge holds a patent for the "Enhanced density modified isoplanar process." This improved process for fabricating modified isoplanar integrated circuits with enhanced density incorporates several interactive and co-acting process steps. The first step involves oxide isolation of epitaxial islands in a two-step process, which forms a thin thermally grown oxide layer over the surfaces of shallow trenches and fills these trenches with deposited low-temperature oxide. The second step utilizes an enhanced single polycrystalline or polysilicon layer process that employs a blanket implant, eliminating certain masking and etching steps while defining the polycrystalline layer. The third step introduces a new method and structure for dielectrically isolating and separating contact locations on different surface levels of the integrated circuit structure. Finally, the process ensures that all electrical contact locations for the elements of the integrated circuit structure are at the same substantially isoplanar level.
