Title: Semiconductor substrate having alignment mark and alignment using said mark
Inventor: TSUJITA KOICHIRO
IPC: H01L21/027
Filed: 1987-08-25
Abstract: PURPOSE:To correct a position to be aligned by a method wherein, in a semiconductor substrate where an alignment mark used for alignment of a wafer with a reticle has been formed, at least three alignment marks are arranged inside a region on the water to be aligned with the reticle. CONSTITUTION:Four wafer alignment marks 6a, 6b, 6c, 6d are arranged symmetrically; however, it is enough if at least three or more wafer alignment marks are arranged inside one shot on a wafer. The alignment marks refer to the marks with which both a position in X coordinates and a position in Y coordinates can be identified by referring to one mark. Accordingly, if the alignment marks for X coordinates use are separated from those for Y coordinates use, at least three marks are required for X use and for Y use, respectively. It is preferable that a position of the wafer alignment marks is away from the center of a shot from a viewpoint that an error in a reduction magnification and an error in a reticle rotation are measured; the measuring accuracy of the errors is enhanced. In addition, the wafer alignment marks are situated at an edge inside the shot, it becomes easy to manufacture a reticle of a semiconductor device.

Inventor: ENDO HIROYUKI
IPC: H01L27/01
Filed: 1985-09-24
Abstract: PURPOSE:To increase the precision of trimming by a method wherein a third resistor is provided in parallel with a first resistor to realize the relative precision of the first resistor and a second resistor which are the factors of a balance characteristic, first the absolute precision of the first resistor is trimmed, and then the third resistor is trimmed. CONSTITUTION:A third resistor R3 is provided in parallel with a first resistor R1 so that the relative precision of a second resistor R2 between terminals 1 and 2 and of the first resistor R1 between terminals 3 and 4 be set within + or -0.1%. So as to obtain a relative precision + or -0.1% in relation to an absolute precision 100OMEGA+ or -0.5%, for instance, the first resistor R1 is set beforehand to be of about 102OMEGA, somewhat larger than 100OMEGA of the second resistor R2. First the second resistor R2 is trimmed to be of 100OMEGA+ or -0.5%, and then the third resistor R3 is trimmed so that a specific precision be within + or -0.1%. When the precision is set thereby within the relative precision + or -0.1%, trimming is ended. Since the working rate of the third resistor R3 contributing to + or -0.1% is 1/20 of 100OMEGA, the trimming can be performed very easily.

Abstract: PURPOSE:To enable rapid scanning with a simple construction by driving the titled device so as to take a fixed relative position against a CCD element by a method wherein two CCD elements are arranged, and scribe lines are detected by analyzing wafer image signals by a computer. CONSTITUTION:If the direction of the scribe line 4 on the wafer is not coincident with the direction of the CCD elements 1 and 2 (of scanning), the superposition of signals by the shift registers 7a and 7b of a cut-out circuit 7 is not carried out, but the signals are inputted from the cut-out circuit to a frequency distribution circuit 8 at high frequency.

IPC: G11B7/09
Filed: 1991-08-23
Abstract: PURPOSE:To facilitate stable tracking operation by discriminating the direction of positional deviation between irradiated light and a guiding groove based upon meandering information and the reflected light, and then by relatively controlling a position between the guiding groove and the reflected light according to the discriminating result so as to reduce the offset of tracking signal. CONSTITUTION:A photodetector provided with photoelectric conversion elements A, B, C and D converts the light reflected on an optical disk into electrical signal and, by an adder 22 and a subtractor 23, obtains a sum signal HF and a difference signal TE, respectively. The TE is inputted into a wobbling separation means consisting of a BPF 25 and a comparator 26 and is separated from a wobbling content so as to output a meandering information ATIP. The HF and the ATIP are arithmetically processed in the interrelation with the LIF and the TE by a BPF 24, a multiplier 27 and an integrator 28. The comparator 29 discriminates the direction of positional deviation between an irradiated light and a guiding groove and then controls a relative position between the guiding groove and the irradiated light through a U/D counter 30 based upon the discriminating result. So, the affection from an offset is reduced and stable operation is realized.
