Title: Trimming element and electrical short-circuit thereof
Inventor: IMAMURA KAORU
IPC: H01L21/82
Filed: 1988-01-20
Abstract: PURPOSE:To facilitate a reduction in a trimming resistance value by a trimming processing by a method wherein alloy layers, each consisting of the metal of electrodes and the material of an inter mediate layer, are grown on the intermediate layer and the state between the electrodes is substantially short-circuited electrically. CONSTITUTION:When a laser beam (l) is irradiated on a poly Si layer (intermediate layer) 22 through a gap 25 between Al electrodes 23a and 13B, the layer 22 generates heat. As the electrodes 23a and 23b have a high heat conductivity compared to the layer 22 and the optical energy that the electrodes absorb directly from the laser beam is also small, the electrodes 23a and 23b are held at a comparatively low temperature. Accordingly, the poly Si layer under the part of the gap 25 generates heat most, is brought into a high-temperature state and Al-Si alloy layers begin to grow from the electrode surfaces which come into contact to this poly Si layer. By irradiating further the laser beam, the alloy layers are grown in the thickness direction of the poly Si layer and at the same time, are grown in the lateral direction as well and both alloy layers grown from right under the electrodes 23a and 23b come into contact to each other. When a trimming element 50 reaches this state, the state between the electrodes 23a and 23b is brought into an electrically short-circuited state by the Al-Si alloy layers 24.

Title: End point detector
Inventor: MEGA HIRONAO
IPC: H01L21/3065
Filed: 1987-01-20
Abstract: PURPOSE:To detect an emission spectrum with high resolving power, and to detect the end point of film formation positively by a method wherein emission spectral intensity is converted into voltage, amplified and observed, a maximum value is predicted from a voltage rise after discharge starting and amplification gains are corrected automatically. CONSTITUTION:An emission spectral intensity signal converted 3 into voltage is amplified 4, multiplication type D/S converted 8, and A/D converted 7 and input to a CPU 5. The CPU predicts a peak value from the rise of emission spectral intensity, and computes amplification gains so that the peak value is brought close to the full scale of the A/D converter 7 and feeds back a computed value to the multiplication type D/A converter 8. According to the constitution, gains are corrected automatically so that the A/D con verter is full-sealed even to the level variation of emission spectral band intensity, thus detecting spectral intensity with high resolving power, then positively detecting an end point.

Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To form fine wiring of low resistance and improve productivity,by setting the temperature of developer in which glycerol is added at a specified value, and forming a resist pattern. SOLUTION: Gate wiring is constituted on a substrate in which a polycrystalline silicon film is formed via a gate insulating film. A resist pattern is formed on the gate wiring. The gate wiring and the resist pattern are used as masks, and a semiconductor region of a polycrystalline silicon film transistor array is formed by implanting ions in the polycrystalline silicon film. In this case, a resist film is formed on the gate wiring, and exposed in a specified pattern. In order to restrain dissolution of aluminum forming the gate wiring, developer containing dihydric alcohol or trihydric alcohol at 21 deg.C is used to dissolve an exposed part, and the resist pattern is formed. As a result, the film thinning amount of the resist film can be restrained, and imperfect etching can be prevented.
