Latest Patents

Ronfu Chu's latest patents include a CMP machine dresser and a method for detecting the dislodgement of diamonds from the same. The CMP machine dresser features a substrate with a first and second conductive layer, both isolated within the substrate. A plurality of diamonds is mounted in these conductive layers, and a bonding layer is used to attach the diamonds. This design allows for the detection of conductive materials that penetrate the original position of the diamonds when any diamond dislodges, thus determining the dislodgement effectively.

Another significant patent is a method of optical correction aimed at improving pattern shrinkage caused by light scattering during photolithography processes. This invention corrects patterns on photomasks by introducing aid patterns, eliminating the need for serifs or hammerheads, which reduces costs. The method involves placing a chrome aid block between the edges of the patterns, sized between one-third to one-half the wavelength of light used during exposure. This innovation minimizes pattern shrinkage and prevents the standing wave effect, leading to more accurate pattern transfers.
