Title: Clyde H Browning: Innovator in Lithographic Technology
Introduction
Clyde H Browning is a notable inventor based in Briarcliff, Texas, recognized for his contributions to the field of integrated circuit design. With a total of two patents to his name, Browning has made significant advancements in lithographic processes that are essential for semiconductor manufacturing.
Latest Patents
Browning's latest patents include a method for two-dimensional lithographic proximity correction using design rule check (DRC) shapes. This innovation addresses the challenges posed by the shrinking size of integrated circuit designs. As the exposure wavelength of light becomes shorter than the smallest dimensions of circuit elements, traditional lithographic processes face limitations. Browning's approach involves altering circuit designs to ensure that the final printed results closely match the intended design. This process, known as Lithographic Proximity Correction (LPC), incorporates shape manipulation functions to add various serifs to the designs, enhancing the accuracy of the pattern transfer.
Another significant patent focuses on minimizing unwanted metallization in peripheral die on a multi-site wafer. This method involves creating a first mask key that contains essential information, such as alignment cues and test structures. By modifying this key to produce a second mask key, Browning ensures that the two keys overlap when transferred to adjacent sites on the wafer, effectively preventing double exposure of the information.
