Title: Device for measuring film thickness
Inventor: SASABE SHIYUNJI
IPC: H01L21/205
Filed: 1983-04-15
Abstract: PURPOSE:To improve an SN ratio and the measurement precision of film thickness by projecting light from a polarized laser light source upon a film to be measured through a beam splitter and an lambda/4 plate, and detecting interference reflected light by a sensor through a linear polarizing plate. CONSTITUTION:P Polarized light projected by the polarized laser oscillator 14 illuminates an SiO2 film 8 on the surface of a semiconductor wafer 5 through the polarized beam splitter (PBS)15, reflecting mirror 13, view spot glass 12, and lambda/4 plate 11. The interference reflected light travels backward and is reflected by the PBS15 and then detected by the photosensor 18 through the linear polarizing plate 16 and an interference filter 17. Its detection output is processed by a microcomputer 21 through an amplifier 19 and an AD converter 20 to calculate the film thickness. Noise light reflected by the PBS15 and view spot glass 12 is cut off by the linear polarizing plate 16 and the spectrum width is restricted by the interference filter 17, so the SN ratio is improved and the measurement precision of the film thickness is also improved.
