Latest Patents

Tachi's latest patents include innovative methods for grinding semiconductor wafers that enhance nanotopology. One of his patents describes methods for holding a workpiece with a hydrostatic pad. This pad features hydrostatic pockets that are strategically formed in a face of the body directly opposed to the wafer. These pockets are designed to receive fluid, creating a barrier between the body face and the workpiece while applying necessary pressure during grinding. The hydrostatic pads allow the wafer to rotate relative to the pads about their common axis. Additionally, the orientation of the pockets helps reduce hydrostatic bending moments that can occur when grinding wheels shift or tilt, thereby preventing degradation of the wafer's surface.

Another patent focuses on a wafer clamping device for a double-side grinder. Similar to his previous invention, this hydrostatic pad is utilized to hold a semiconductor wafer securely during the grinding process. The design ensures that the wafer remains stable and maintains its integrity, even when subjected to the dynamic forces of grinding.
