His innovative work has paved the way for advancements in wafer etching techniques and semiconductor packaging.

Latest Patents

One of Rogers' latest patents focuses on wafer etching techniques. This method describes a process for etching a through via on a wafer of semiconductor material. The process involves applying a layer of photoresist material to the backside surface of the wafer, exposing it to a light source through a mask, and then developing the photoresist to form at least one via. The remaining photoresist layer is baked to create a hardened layer, followed by gas plasma etching of the semiconductor material to form a through via. Finally, a layer of conductive material is applied to establish electrical connectivity between the backside and front side surfaces.

Another notable patent by Rogers is for an inexpensive wafer-level MMIC chip packaging. This design incorporates a stress relief buffer between the chip and the metal carrier layer to absorb thermally induced stress. The buffer is made from a flexible polymer that can be etched and has a coefficient of thermal expansion similar to that of the chip. This innovative packaging solution ensures reliable performance over a range of operating temperatures.
