Latest Patents

Among his most notable inventions is a method of extracting heat from semiconductor bodies to improve the cooling of densely packaged devices. This innovative approach utilizes microchannels that extract heat through forced convection, employing fluid coolants positioned close to heat sources. The design of these microchannels maximizes the heat sink surface area and improves heat transfer coefficients, allowing for higher power density in semiconductor devices without compromising junction temperatures or reliability.

In one of his preferred embodiments, Ostop’s invention includes the integration of a plurality of microchannels directly within the substrate of silicon or silicon carbide chips. These microchannels feature closed-ended slots or grooves with a generally rectangular cross-section and utilize various fabrication methods such as deposition and etching, micromachining, and laser cutting techniques.

Another of Ostop’s significant innovations is a die attach procedure for silicon carbide (SiC) that implements a scrubbing technique to securely bond a SiC die to a package. This method involves a multi-layer formation process where a nickel layer is applied to the SiC die, followed by the deposition of an amorphous silicon layer, which then forms a eutectic with gold plating on the package during the scrubbing process.
