Title: The Innovative Contributions of Shauna Marie Leis
Introduction
Shauna Marie Leis is a prominent inventor based in Georgetown, KY (US). She has made significant contributions to the field of ink jet technology, holding 2 patents that showcase her innovative spirit and technical expertise.
Latest Patents
One of her latest patents is titled "Ink jet printheads and methods therefor." This invention provides a method for making ink feed vias in semiconductor silicon substrate chips for an ink jet printhead. The method includes applying a first photoresist material to a first surface side of the chip, which is then patterned and developed to define at least one ink via location. An etch stop material is applied to the second surface side of the chip, and at least one ink via is anisotropically etched through the thickness of the silicon chip. This method significantly improves the throughput of silicon chips and reduces losses due to chip breakage and cracking, resulting in more reliable chips for long-term printhead use.
Another notable patent is the "Method for making ink jet printheads." This invention provides an improved method for grit blasting slots in a silicon wafer. The process involves applying a first substantially permanent non-water soluble layer to the first surface of the wafer, followed by a water-soluble protective material. Grit blasting slots corresponding to individual semiconductor components is then performed, enhancing protection for the electrical components during the process and increasing the yield of usable semiconductor chips.
