IPC: G01B11/26
Filed: 1984-08-07
Abstract: PURPOSE:To correct the turning angle of a semiconductor chip highly accurately in preparatory positioning, by picking up the image of the semiconductor chip, obtaining the turning angles of a plurality of predetermined segments of the outer surface of the said chip by the image signal, and detecting the amounts of deviation of said angles from the predetermined positions. CONSTITUTION:Light L from a light source 64 is projected on a semiconductor chip 3, which is mounted on a tray 18 on the upper surface of an X-Y-theta table 17 of preparatory positioning mechanism, through a condenser lens 62 and the like. The light L, which is regularly reflected by the semiconductor chip 3, is inputted to an image processing part 65 through an objective lens 64 and an ITV camera 59. In the imgae processing part 65, the amount of deviation between the center S of the chip 3 and the light axis O is computed. The relative positions of six points, e.g., A-F in the directions of X and Y are recognized. The slant angles of the segments AB, BC, DE and EF are obtained by trigonometry. The computed values are outputted to a driving part 54 through a computer. The turning angle of the chip 3 is made to agree with a reference value.

IPC: H05K13/04
Filed: 1987-07-03
Abstract: PURPOSE:To prevent inclination or bounding of a substrate during fixing of the substrate and hence to avoid deviation of components to the substrate or damages to the components and the substrate, by providing substrate push-up pins at the opposite ends of transport rails such that they can be projected and retracted. CONSTITUTION:When transport rails 1 are lowered, a positioning hole 3' in a substrate 1 is fitted on a positioning pin 5. Shafts 7a of substrate push-up pins 7 are contacted with the top face of a mounting table 4 and pushed up by the table 4. Thereby, the substrate 3 is pushed up in parallel with the oppo site ends of the substrate supported by the heads 7b of the push-up pins 7 until the opposite ends of the top face of the substrate 3 are applied against the upper face of the rails 1. The substrate 3 is thus clamped between the faces of the upper recessed parts of the transport rails 1 and the heads 7b of the push-up pins 7 and is enabled to be transported without inclination or bounding. As the transport rails 1 ascend, the substrate push-up pins 7 are lowered by gravity and return to the initial position.

Abstract: PURPOSE:To form an image whose magnification is constant irrelevantly to displacement by arranging the image formation surface of a two-dimensional image sensor in parallel to the optical axis of a projection optical system and setting the optical axis of a photodetection optical system at right angles to the optical axis of the projection optical system. CONSTITUTION:The photodetection optical system 3 and projection optical system 2 are arranged so that their optical axes cross each other at right angles. The image formation surface of the two-dimensional image sensor 4 is set in parallel to the optical axis of the projection optical system 2 and at the position where the photodetection optical system 3 covers the displacement states (a)-(c) of an object 5 of measurement within an about 45 deg. half view angle range. The power of a cylindrical lens 21 is so adjusted that the width of a light image formed on the two-dimensional image sensor 4 is wide enough to cover a specific number of picture elements on each picture element line. Consequently, the distance from the object of measurement to the photodetection optical system is constant in each displacing operation, so the magnification of the image is constant irrelevantly to the displacement.
