Latest Patents
One of Ralph's latest patents is titled "Interposer for maintaining temporary contact between a substrate and a test bed." This invention discloses an interposer and test structure designed to facilitate contact between a substrate and a test bed. One embodiment features a floating, rigid conductive element within a nonconductive body, allowing for temporary contact between the test bed and the substrate. Another embodiment includes two layers of material, where one layer has pogo pins for contacting the substrate, while the other layer has pads for contacting the test bed. The pogo pins are arranged in a grid that corresponds to the substrate input/output pads, and the interposer pads align with the pogo pin contactors of the test bed.
Another significant patent is the "Chemical-mechanical polishing system having a bi-material wafer backing film and two-piece wafer carrier." This system describes a wafer backing film with concentric first and second portions, along with a wafer carrier that has corresponding portions for mounting the wafer backing film. The second portion of the wafer backing film is annular and surrounds the first portion, while the second portion of the wafer carrier is adjustable vertically. This design ensures that the outer edge of the wafer is sealed when backside air is applied during a film removal process.
