Latest Patents

One of Bandy's latest patents is the "Substrate Edge Clamping Force Tester." This innovative apparatus and method are designed to measure the clamping force applied to a substrate by clamping elements of a substrate holder. The apparatus includes a pneumatic cylinder, a two-position, three-way valve, and a pressure gauge. In the first position of the valve, the gauge and bore of the cylinder are vented or pre-pressurized. In the second position, the bore and gauge are isolated. The method involves placing the apparatus with the valve in the first position between clamping elements set to a non-clamping position, moving the valve to the second position, setting the clamping elements to a clamping position, and reading the pressure on the gauge.

Another significant patent is the "Method and Apparatus for Calibrating Sensors that Detect Wafer Protrusion from a Wafer Cassette." This calibration gauge includes a disk with a first region that is a circular sector of a central angle A, having a constant radius R about a center, and an integral second region of increasing radius about the center. The increasing radius extends from R to R through a central angle A, where R is greater than R and A + A equals 360°.
