Latest Patents

John E Leiss holds a patent for a method titled "Self-aligned trench with selective trench fill." This patent describes a technique for fabricating a self-aligned trench structure in a semiconductor device. The method involves using an oxidation-resistant material with an opening as a masking layer. A sidewall spacer is applied to protect a portion of the substrate from etchant attack during trench formation. The trench is then filled with a selective deposition of trench fill material, utilizing a seeding material on the trench's sidewall as a nucleation site. After filling, the sidewall spacer is removed, and the substrate is oxidized to create an electrical insulation region around the trench. Finally, the mask layer is removed, and the remaining substrate is doped using the insulation region as a dopant mask. This innovative method has the potential to improve the efficiency and reliability of semiconductor devices.
