Title: Photosensitive composition
Inventor: NAITO TAKUYA
IPC: G03F7/039
Filed: 1993-03-15
Abstract: PURPOSE:To obtain a resist having high contrast and high sensitivity by preparing the photosensitive compsn. from a compd. having substitutents which is decomposed by acid, a compd. which produces acid by irradiation with chemical radiation, and a compd. which neutralizes acid and is decomposed by irradiation with chemical radiation. CONSTITUTION:In an unexposed area of a resist layer 12, an acid generated by heating after exposure and an acid 17 diffused from an exposed area 14 are generated, but the excess acid is trapped by a compd. 18 included in the resist layer, neutralizing acid and decomposed or lowered in the neutralizing strength of acid by irradiation with chemical radiation. Thus, the concentration of acid is decreased. On the other hand, in the exposed area 14, the compd. 18 is decomposed or lowered in its neutralization strength so that the concentration of acid is not affected by the compd. Thereby, the difference of amounts of produced acid between in the exposed area and unexposed area is enlarged, thereby, the reaction amt. of compd. having substitutents decomposed by acid increases. As a result, the difference of solubility to a developer at the time of development is increased and contrast in the resist pattern is enhanced.

Title: Direct-current motor drive equipment
Inventor: NISHI TADASHI
IPC: H02P1/22
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To prevent excessive current from being passed through a relay which switches the direction of the rotating for a direct-current motor, thereby prolonging the contact life of the relay. SOLUTION: When a forward revolution command switch 7 is turned off in equipment 10, a timer circuit 14 for delaying reverse operation is caused to perform time-limited operation to keep off a reverse revolution inhibiting switch 13 for a certain period of time, thereby delaying the excitation of a relay 6 for reverse revolution. When a reverse revolution command switch 8 is turned off, a timer circuit 15 for delaying forward operation is caused to perform time-limited operation to keep off a forward revolution inhibiting switch 12 for a certain period of time, thereby delaying excitation of the relay 6 for reverse revolution.  As a result, generated current and the starting current of the motor are prevented from being superposed with the same phase when the direction of the revolution of the motor 2 is switched, and thus excessive current is prevented from passing through the contact of the relay.

Title: Lead bend inspection device
Inventor: TSUJIMURA HIDEYUKI
IPC: H01L21/66
Filed: 1990-03-06
Abstract: PURPOSE:To eliminate generation of judgment error caused by bent leads on both sides by installing a detector that measures the distance up to the tip of a lead side projecting from the side of a semiconductor device on the same straight line oppositely to each other, computing the results of each distance measurement, and deciding the results. CONSTITUTION:It is assumed that DUT 3 glides and the leads 2, 2a, 2b... 2n of the DUT 3 come to the front of detectors 1c and 1d. A that time, the first detected leads are assumed to be 2 and 2a. The detector 1d is to determine the distance up to the lead 2a while the detector 1c is to determine the distance up to a package side below the root of the lead 2 and the DUT 3. In this case, the detectors 1d and 1c are positioned on the same straight line with the leads 2a and 2. In this manner, the distance up to each lead is sequentially determined. It is possible to detect only the difference from the sum of the distances obtained from each opposite lead. More specifically, if an attempt is made to determine 'standard value of sum' in advance, the determination will not be subjected to a zigzag motion of a package. In addition, the difference against that value is a bending value in its lateral direction.

Abstract: PURPOSE: To make the combination of negative-type and positive-type resistors as well as the combination of the same type possible by causing an upper-layer photo resistor to adhere to a lower-layer photo resistor after inactivating the lower- layer photo resistor by Freon gas plasma.  
     CONSTITUTION: SiO 2  film 2 is caused to adhere onto semiconductor substrate 1, and negative photo resistor film 3 is applied to film 2, and the substrate is stored in the plasma processing unit for dry etching. Next, after heating at 80°C for about 10 minutes, film 3 is changed to inactivated film 3' by the CF 4  gas plasma processing for two minutes under vacuum degree 0.5 Torrs, high-frequency output 150W and frequency 13.56MHz. After that, positive resistor film 4 is applied onto film 3' and is subjected to light exposure. However, since lower-layer film 3 is inactivated, N 2  gas is not generated not to damage the close adhesion property between films 3 and 4. Next, film 4 is developed, and the substrate is put in the processing furnace again and is subjected to the O 2  gas plasma processing for 5 minutes under vacuum degree 1.0 Torr and high-frequency output 200W, thereby removing exposed film 3.
