Latest Patents

One of his latest patents is titled "Net shaped articles having complex internal undercut features." This invention describes a novel production method for manufacturing metal and ceramic articles with intricate internal undercut features using powder injection molding processes. The method involves initially molding the shape of the undercut feature using a disposable material, such as a degradable polymer. The powder injection molding feedstock is then molded onto this feature, encapsulating it within the feedstock. After processing, the polymer is removed, resulting in a powder skeleton that retains the internal undercut feature. This innovative approach eliminates the need for complex tooling or costly secondary operations while allowing for flexible design of complex geometries.

Another significant patent is "Enclosure for a semiconductor device." This invention outlines a method to create a combined enclosure and heat sink structure for semiconductor devices. It involves preparing two different feedstocks with specific mixtures of powdered metal materials, lubricants, and binders. These feedstocks are pressed to form green parts, which are then sintered to complete the structure. The process ensures that the first and second powdered skeletons are in intimate contact during sintering, enhancing the overall performance of the semiconductor device.
