Latest Patents

One of Rust's latest patents is the "Hollow Cathode Type Magnetron Apparatus Construction." This invention features a hollow cathode type inverted cylindrical magnetron apparatus that consists of two separate units, each with a rectangular C-shaped cross-section. These units are positioned together to create a hollow rectangular parallelpiped cavity, allowing articles to be sputtered through this space. The design employs bolted construction using simple geometric elements, resulting in a cost-effective and easily serviceable structure. The magnetron utilizes permanent magnets with uniform north-south pole orientation, strategically placed behind the target material and surrounded by magnetic permeable material to confine the magnetic flux path. This configuration minimizes substrate heating while ensuring that the lines of force remain parallel to the substrate surface. Additionally, cooling is facilitated by coolant-carrying tubes interspersed between the magnets and the target material.

Another significant patent by Rust is related to the "Fabrication of CPI Layers." This method involves creating conductive polymer interconnect (CPI) material that incorporates chains of electrically conductive particles within an elastomeric matrix. The innovation improves contact resistance by removing a thin layer of elastomeric material that remains after standard processing. This surface layer is eliminated through plasma etching, allowing the conductive particles to protrude at both surfaces. The protruding particles can then be plated to replace any conductive material lost during the etching process.
