Title: The Innovations of Karen E. Yokoyama
Introduction
Karen E. Yokoyama is a prominent inventor based in Rancho Palos Verdes, CA (US). She has made significant contributions to the field of microelectronics, holding a total of 5 patents. Her work focuses on developing advanced methods for forming connections in high-temperature superconductor circuits and other delicate materials.
Latest Patents
One of her latest patents is titled "Method for forming high frequency connections to high temperature superconductor circuits and other fragile materials." This innovative method describes a process for forming high-frequency connections between a fragile chip and a substrate. The technique involves selectively depositing metal on the surfaces of both the chip and substrate, followed by the evaporation of electrically conductive bumps. These bumps possess spongy and dendritic properties, allowing for a precise alignment and bonding process that results in a robust electromechanical bond.
Another notable patent is the "Reworkable microelectronic multi-chip module." This invention features cold welded microelectronic chips, where the bonding pads of the chips and the substrate are made of metals with differing hardness. This design allows for predictable breakage during chip removal, enabling the replacement of chips without compromising the integrity of the module. The use of Indium as the bonding metal enhances the reworkability and testing procedures for microelectronic applications.
