Title: Johnson O Olowolafe: Innovator in Semiconductor Technology
Introduction
Johnson O Olowolafe is a prominent inventor based in Austin, TX (US), known for his contributions to semiconductor technology. He holds a total of 5 patents, showcasing his innovative approach to developing advanced materials and processes in the field.
Latest Patents
One of his latest patents is for a semiconductor device having a titanium-aluminum compound. This invention includes a process for forming an intermetallic layer and a device formed by the process. The process involves a reaction step where a metal-containing layer reacts with a metal-containing gas, with the metals of the layer and gas being different. In one embodiment, titanium aluminide may be formed on the sides of an interconnect. The process can be performed in various equipment, such as a furnace, a rapid thermal processor, a plasma etcher, and a sputter deposition machine. The reaction to form the intermetallic layer is typically conducted at a substrate temperature no more than 700 degrees Celsius. Another significant patent is for an Al-Ni-Cr conductive layer for semiconductor devices. This aluminum-nickel-chromium (Al-Ni-Cr) layer is used as an interconnect within a semiconductor device. The layer contains about 0.1-0.5 weight percent nickel and about 0.02-0.1 weight percent chromium, ensuring resistance to electromigration and corrosion. The low concentrations of nickel and chromium allow the layer to be deposited and patterned similarly to most aluminum-based layers.
