Latest Patents

At Chuan Chen holds a patent titled "Method for sectioning a semiconductor wafer with FIB for viewing with SEM." This patent describes an improved method for sectioning a semiconductor wafer using a focused ion beam (FIB) apparatus. The method allows for a clearer image of the cut site, which is formed from secondary electrons produced by the beam. This clarity aids the operator in making more accurate cuts. Prior to the FIB cut, a laser is utilized to cut into the wafer, exposing the lowermost layer of silicon dioxide. The oxide and any splatters from the laser cut are then removed with an oxide etcher. The FIB cut can subsequently be made without splattering silicon dioxide over the area being viewed. A low beam current is employed for the FIB cut, ensuring precision and quality in the process.
