Title: Pattern deviation measuring device
Inventor: FUJIWARA MAKOTO
IPC: H01L21/66
Filed: 1990-09-27
Abstract: PURPOSE:To ensure a satisfactorily accurate measurement stable over a long period of time by adjusting, provided a pick-up electric signal of a measurement mark formed on a wafer is outside a reference level, an output of a power supply by a control signal corresponding to the aforementioned pick-up electric signal. CONSTITUTION:Wide band illumination light from a light source 8 to which power is supplied from a power supply 9 illuminates a region of a measurement mark 2 on a wafer 1, and reflected light from the region enters a device via an objective lens 3, a prism 6, and a lens 4. The light is then photographed by a CCD camera 7 for photographing the foregoing region for conversion to an electric signal. A signal processing part 10 detects the end surface of the mark 2 based upon the electric signal and a displacement detector part 11 estimates a pattern displacement. Simultaneously, the processing part 10 compares the converted electric signal with a reference value whereby the power supply 9 is controlled through a power supply control part 12. With the construction where the light amount of a measured mark image is automatically adjusted to a proper value a highly accurate measurement is achieved stably for a long period of time.

IPC: H01L21/316
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To suppress fluctuations in the linewidth of a resist pattern caused by fine fluctuations of the thickness of an underlying film. SOLUTION: Sequentially deposited on a silicon substrate 1 are a silicon oxide film 2, a silicon nitride film 3 and a polysilicon film 10.
