Recent advances in the computer industry and the rapid commercialization of advanced information systems such as multimedia devices, which is underpinned by various large-scale integration (LSI) devices such as microprocessors and memory. The LSI technology is developing very rapidly, with the device density doubles approximately every 2 years. A higher LSI device density means that there are a larger number of devices built into each chip, and the key is to make each device as small as possible. The fundamental technology for realizing this is fine geometry processing, which is mainly comprised of the etching. Etching is a technology for transferring the circuit patterns onto the underlying thin film by partially removing the various thin films deposited on a wafer. The etching scheme is designed to ensure the etching uniformity, which is one of the important indicator for evaluating process stability. After the etching process has been completed in the thin film, the semi-finished products need to be tested and analyzed for confirming etching effect and whether the process can continue.
