Title: Exposing method for electron beam
Inventor: KATO SHINYA
IPC: H01L21/30
Filed: 1986-03-17
Abstract: PURPOSE:To reduce a proximity effect by drawing a resist film while heating to weaken the intensity of a beam. CONSTITUTION:A stage 3a has a heater 3b therein to be able to be heated. Accordingly, a resist film 2 on a substrate 1 placed on the stage 3a is heated by the heat of the stage 3a. A pattern is drawn by exposing by emitting an electron beam 4 having weak intensity to the film 2 while heating the film 2. The film 2 arrives at photosensitive state by the emission of an electron beam 4 having weaker intensity than when it is not heated by heating it to a suitable temperature which does not subject it to chemical change until the photosensitive state is reached. When the intensity of the beam 4 is weakened, the temperature rise of the substrate 1 between the starting time point and the finishing time point of drawing decreases. Thus, proximity effect is reduced to facilitate the high integration of a semiconductor device.

Title: Manufacture of through hole substrate and inspection method for through hole
Inventor: TOMINAGA HIROSHI
IPC: G01N21/88
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To enable inspection of even fine through holes by making light of a spot light source parallel to project onto a through hole substrate and detecting the leaked light from the through holes. SOLUTION: Through holes are irradiated with light of a sot light source 13 through a lens 14 from below a printed circuit board 1 being conveyed by a belt conveyor 10. The light passing through the through holes is caught by a line sensor camera 11 to aggregate the number of the through holes with a number of hole converting device 12. In this process, the light of the spot light source 13 is made substantially parallel by the lens 14 and when a relationship of D/H tan θ (wherein D represents the diameter of through holes and H the thickness of printed substrate 1) is met, the light can pass through the through holes so that the leaked light is focused onto the line sensor camera 1. This enables inspection of piercing through microscopic holes and also allows automation thereby shortening inspection time.

Abstract: PURPOSE:To obtain a high-precision detector of simple structure which is assembled easily by obtaining variation in facing area between a fixed electrode and a rotary electrode which is displaced according to the rotary displacement of a body to be detected in the form of electric variation, and thus detecting the rotary displacement. CONSTITUTION:When a rotating shaft 1 rotates by an angle theta according to the rotary displacement of the body to be detected, the rotary electrode 2 also rotates around the shaft 1 by the angle theta to shift in relative position from the fixed electrode 4 by the angle, and the facing area between the electrodes 2 and 4 is proportional to the angle theta.
