Overview

The QS1200 is a desktop FTIR metrology tool designed for advanced semiconductor fabs. It is used for dopant monitoring, epi thickness measurement, and other applications. The tool can accommodate SEMI standard wafers of 100, 125, 150, 200, and 300mm diameter, as well as odd shaped wafer pieces and 2mm thick silicon slices. An optional single wafer mapping stage is available for all wafer sizes. The QS1200 also features unique algorithms for instant qualification of SOI, SiC, and other epitaxial films. Its built-in intelligence extends its applicability to almost every film material imaginable. Additionally, it is versatile enough to qualify the thickness of recycled test wafers for rapid payback. This tool provides a new level of integration of the FTIR technique utilizing proven optical technology.
