Abstract: PURPOSE:To achieve an accurate adjustment by adjusting individual devices so that the value of combined vector is always constant when a first phase detection output and a second phase output detected by use of a signal shifted by 90 deg. in the phase are combined in vectors. CONSTITUTION:An IF signal (a) and a COHO signal (b) are inputted into a phase detector 1, which outputs a video signal according to a phase signal of both the signals.

Title: Inspection of wiring conductor
Inventor: HIRANO TORU
IPC: G01R31/02
Filed: 1987-01-09
Abstract: PURPOSE:To inspect the position of a defect without being influenced by the wiring density, in a short time and accurately, by a method wherein a designwise wiring conductor is compared with an actually wired conductor which has been manufactured on the basis of the designwise wiring conductor. CONSTITUTION:When, for the detection of a short-circuited part 5 at an actually wired conductor, a positive-type designwise wiring conductor part 2 and an actually wired conductor part 3 are stacked up and the light is radiated from a light source so as to detect the transmitted light by using an image sensor, the positive-type designwise wiring conductor part 2 and the short-circuited part 5 are opaque and do not transmit the light; accordingly, this position can be detected. On the other hand, if a disconnected part 4 of the actually wired conductor is to be detected, a negative-type designwise wiring conductor 7 and the actually wired conductor part 3 are stacked up and the light is radiated from the light source so as to detect the transmitted light by using the image sensor; because only the disconnected part is transparent and the light is transmitted, its position can be detected. By this method, it is possible to detect the existence of a defect and the position of the defect at the actually wired conductor part without being influenced by the wiring density, in a short time and accurately.

Both tip 4a of region 4 and surface 1a of substrate 1 are formed nearly in the vertical direction regardless of the shape of part 3a. Thus, a proper control is ensured in case the PN junction is formed laterally to substrate 1.
