Abstract

This article concerns an improved optical beamsplitter used for visually aligning multiple objects, for example, a semiconductor chip and a substrate, during chip mounting. The improved beamsplitter features a modified construction and beam path that avoids erroneous alignment caused by defects which may arise in the beamsplitter.
