Latest Patents

Ferguson's latest patents include innovative processes for forming semiconductor devices. One of his key inventions involves the use of beveled clamp fingers in an etching system. The beveled top surfaces of these clamp fingers allow etching species to attack the layer being etched more readily, thereby reducing the size of halo regions. In other embodiments, he explores the use of triangular clamp fingers or clamp fingers with rounded top surfaces. Another significant patent details a process for dry etching a passivation layer of a semiconductor device. This process utilizes a low radio frequency (RF) power step when an underlying bond pad is initially exposed, followed by a high RF power step after the initial exposure. This method effectively minimizes the likelihood of bond pad staining, especially when a polyimide die coat layer is subsequently formed over the semiconductor device.
