With a portfolio of eight patents, Engelke's innovations focus primarily on methods for creating and utilizing particle beam masks for advanced imaging processes.
Latest Patents
Engelke's recent work includes cutting-edge patents that address complex challenges in pattern fabrication. One notable patent describes a method for the fabrication of particle beam masks. This innovative process automatically splits a layout of a hole pattern into two complementary arrangements for various particle beams, such as x-ray, electron, and ion beams. By determining all inside and outside corners of the pattern, the method establishes a stability value, allowing for division into stable sections that can be evenly distributed across two masks.
Another recent patent outlines a method of transferring a pattern into a radiation-sensitive layer. In this method, two partial patterns are used, which, when aligned correctly, yield the desired final pattern. This approach allows for overlapping elements of the partial patterns, utilizing radiation exposure to achieve precise design specifications. The method is particularly useful for transferring complex patterns requiring multiple masks, especially when annular elements are involved.
