Title: Controller of position and gradient of target
Inventor: KIN SOUTETSU
IPC: G03F9/00
Filed: 1995-08-23
Abstract: PROBLEM TO BE SOLVED: To enable a control device to control the position and inclination in the direction of the optical axis of a target, such as a wafer, in such a way that at the time of the exposure of a semiconductor material or the like, the position and inclination are detected at the same time and are kept within the range of the focal depth of a projection lens. SOLUTION: Light of a light source 1 passes through a first mask 2 and thereafter, with the light condensed on a second lens 32, the light is reflected by a first mirror 4 to proceed to a target 300, such as a wafer on a support stage 200 and is reflected here. After this reflected light is reflected by a mirror 5, the path of the reflected light is divided into two paths by a first beam splitter 21. The light of the path on one side of the two paths is imaged on a first phtotodetector 11 via a lens 33, and the light of the other path is imaged on a second phtodetector 12 via a lens 34. An image of an asymmetrical shape is carved in the mask 2, and the reflected image is detected by the phtodetectors 11 and 12, consisting of a CCD or the like.  A control part 350 compares this reflected image with a reference image at the time when the target 300 is situated at a prescribed position and adjusts the position of the stage 200 via a drive unit 250.

Abstract: PURPOSE:To discriminate rapidly and positively the posture and direction of an 1C element, by installing combinedly a TV-camera a TV monitor and pair of photoelectric converting elements and processing the difference of two electric signals issued out of them. CONSTITUTION:An 1C element 1 placed on a belt B receives lighting 2 from an obliquely above position and a TV-camera 3 picks up its shape to display it 1a on TV monitor 4. Here, a pair of photoelectric converting elements 5, 6 mounted positioned on an image plane of the TV 4 make bright and dark photoelectric conversion of the image 7a by a notched part 7 featured by the directional identification of each element 1 and these two converted electric signals are transmitted to a differential amplifying circuit 8 respectively. The circuit 8 detects a difference of these two electric signals and it the direction of the element 1 is correct, bright and dark difference is caused in the luminous intensity of the light illuminating the element 5, 6 and this turns on a indicating lamp 9. On the other hand, a notched part 7a is located on the righthand side of the monitor plane, because of its absence of the difference of the electric signals from the elements 5, 6, the lamp 9 is not turned on. Thus, in this case directional posture of the element 1 can be discriminated as incorrect.
