Abstract
In this paper we present a novel spatially resolved sensor to detect the endpoint and monitor spatial uniformity for a plasma etching process. A scanning spatially-resolved optical emission spectroscopy (SROES) system was built and installed in Berkeley's Microfabrication Laboratory. This sensor system consists of a stepper motor, controller, and a monochrometer, which provides an in-situ real-time monitoring of the etching endpoint spatially. In this paper, we show the promise of this spatially-resolved endpoint detector, and explain our hardware design and the future experiment plan.
