Latest Patents

Stephen Hu holds a patent for the "Scribe etch process for semiconductor laser chip manufacturing." This patent describes an improved method for etching a scribe line on a semiconductor wafer. The process involves applying a mask layer to the wafer's surface, photolithographically opening a window in the mask layer along the scribe line, and etching a trench in the wafer using a chemical etchant. This etchant selectively etches through the crystal planes of the wafer, generating a V-groove profile associated with the trench. The final step involves cleaving the wafer along the etched trench by applying force to specific regions of the wafer. This innovative method streamlines the manufacturing process and improves the quality of semiconductor laser chips.
