Title: Laurence Shrapnell Watkins: Innovator in Alignment Technologies
Introduction
Laurence Shrapnell Watkins is a notable inventor based in Pennington, NJ (US). He holds 2 patents that showcase his expertise in alignment technologies. His innovative approaches have contributed significantly to the field of device component alignment.
Latest Patents
Watkins' latest patents include a "Method and apparatus for alignment and bonding" and a "Method for aligning photomasks." The first patent describes a method and apparatus that aligns device components based on an analysis of an image of features of the components to be aligned. The image is analyzed for deviation in component alignment, and a signal, based on the deviation, is sent to a positioning apparatus to adjust the position of the components relative to each other. The image of the components is a top view, which permits measuring deviations in alignment of features on the top surfaces of components. The components are bonded together after alignment, and the alignment accuracy of the bonded components is checked. The second patent outlines a method for aligning photomasks on opposite sides of a wafer by directing light beams through zone plates in one photomask and through aligned transparent slits on the other photomask. Simultaneous detection of the beams by photodetectors indicates alignment, and a method for obtaining precise centering by scanning the slits with the beams is also described.
