He has made significant contributions to the field of technology, particularly in the use of electron beams for various processes. With a total of 9 patents to his name, King has demonstrated a commitment to innovation and advancement in his field.
Latest Patents
One of King's latest patents focuses on a method of using an electron beam to effect processes at two adjacent surface areas of a target, such as a semiconductor wafer coated with an electron-sensitive resist. This method addresses alignment errors that can occur, including wafer distortion. By providing a reference marker, such as a square-etched depression, at the surface of the target, King enables the detection of any misalignment. After processing one area, an electron beam is directed toward the predetermined position of the reference marker. The detection of back-scattered electrons provides a signal that indicates any deviation from the expected position, allowing for accurate alignment before processing the second area. For enhanced precision, an array of reference markers may be utilized between the adjacent areas.
