IPC: G01B11/06
Filed: 1994-03-25
Abstract: PURPOSE: To measure a semiconductor layer with a film thickness of hundreds of micrometers by combining the reflection of an infrared light source with the image of the infrared light source, which are caused by a wafer with the change of the length of a light passage in a Michelson interferometer. CONSTITUTION: A radiation 72 from an infrared light source 62 passes through a Michelson interferometer 66 containing a beam splitter 78 and reflecting mirrors 68, 70. The mirror 68 is movable. The output 86 of the interferometer 66 allows an image to be formed on the surface of a wafer 94, where the surface of the light source 62 is formed, via lenses 88, 90 and a beam splitter 92. The image of the light source 62 is combined with the reflection thereof. The thickness of a Si wafer 94 on an insulator is measured by recording an image on an infrared camera 64 at an increment length in a light passage in the interferometer 66 when the mirror 68 is moved.  It is moved nt ((n) is the refraction factor of Si and (t) is the thickness of a layer to be measured) or more from a zero difference between passage lengths 108 and 110 from the mirrors 68, 70 to the crossing point 112 of a light axis.

Title: Positioning controller for moving body
Inventor: ANDO HITOSHI
IPC: G05D3/12
Filed: 1995-02-23
Abstract: PURPOSE: To eliminate the need to go to a place where a controller is installed when a moving body is operated by comparing the moving direction and distance of the moving body with those stored in a memory circuit and driving a stepping motor continuously in the moving direction by time moving distance stored in the memory circuit. CONSTITUTION: When a moving body 1a is initially moved manually from a predetermined position toward one end position, a counter electromotive force induced in the winding of a stepping motor 2 is processed by a counter electromotive force detection circuit 8. A signal corresponding to the number of steps and the rotational direction is then inputted to a microcomputer 5 which delivers a signal to a drive sequence circuit 4. The drive sequence circuit 4 delivers a sequence signal for shifting the moving body 1a continuously in the initial manual moving direction to a conduction control circuit 3 thus driving the stepping motor 2. On the other hand, a pulse signal is transferred from the memory circuit 6 to the counting circuit in the microcomputer 5 where it is subjected to subtraction.  If a zero signal is delivered from the microcomputer 5 to the drive sequence circuit 4, the stepping motor 2 is stopped thus stopping the moving body 1a at one end position.
