Latest Patents

One of Tom Quach's latest patents is titled "Process for providing clean lift-off of sputtered thin film layers." This unique photoresist process achieves clean and complete lift-off of a thin film layer, such as a sputtered thin film formed on a photoresist above a semiconductor substrate. The process relies on a reentrant photoresist profile that breaks the continuity of the thin film layer, ensuring a clean lift-off. The desired photoresist profile can be obtained through a typical photoresist process preceded by an oxidation process on the semiconductor substrate's surface. This oxidation process creates a thin native oxide layer, allowing for clean lift-off without extra processing steps involving dielectric film deposition and etch.

Another significant patent by Quach is the "Method of fabricating a self-aligned double recess gate profile." This method involves forming a first mask layer over the substrate, followed by a second mask layer with an opening. A recess is etched in the semiconductor through the second mask layer's opening, and the first mask layer's opening is then expanded to form a wider recess aligned to the first. This method is particularly applicable to the formation of self-aligned gate and channel recesses in a GaAs MESFET.
