Patent JP-H0410428-A (JP)
Title: Semiconductor device
Inventor: MAEDA YUKI
IPC: H01L23/52
Filed: 1990-04-26
Abstract: PURPOSE:To greatly and effectively improve electrostatic resistance of an electrostatic protection P-N junction by forming a structure in which a first metal wiring is led from a position farthest from a signal input terminal bonding pad of a first contact. CONSTITUTION:A leading position of a first metal wiring 11 from a first contact 3 is set at a position farthest from a signal input terminal bonding pad 8. Thus, an impedance from the leading position of a second contact 6 of a second metal wiring 7 to the leading position of the contact 3 of a first metal wiring 4 becomes uniform at any current passage of a junction diffused region disposed between the contacts 6 and 3. As a result, a current crossing the junction can be uniformly dispersed as shown by an arrow 10. Thus, an electrostatic resistance of an electrostatic breakdown protecting P-N junction due to application of static electricity can be remarkably improved.

Abstract: PURPOSE:To enhance the accuracy of a reference position, by dividing a rotary part having magnetic body into an encoder part in which a continuous signal is recorded and a reference signal recording part, and arranging magnetoresistance effect elements which are made to face said parts in a specified pattern. CONSTITUTION:N and S poles are continuously recorded on the entire surface of an encoder track 41 of a magnetic body 4, which is attached to a rotary shaft and the like, at a wavelength lambda. N and S poles are recorded on a reference signal track 42 at the rate of one pole per revolution at the same polarity and at the same wavelength lambda. In a magnetic sensor 6-1, which is made to face the magnetic body 4, an encoder part 61a is arbitrarily arranged. A reference signal part is divided into 62-1 and 62-2. Magnetoresistance effect elements R01-R04 are arranged so as to face the tracks 41 and 42. They are separated by 1/4lambda to each other. The elements R01-R04 are connected and a bridge is constituted. Thus a width w2 of a reference position signal can be made smaller than the wavelength lambda.

Filed: 1990-04-27
Abstract: PURPOSE:To decrease substances attached to a capillary drastically and improve the lifetime of its capillary by applying a surface activator containing organic carbon to the surface of an extra fine wire made of gold or an alloy of gold. CONSTITUTION:Surface activators containing organic carbon are prepared and solutions of respective agents are applied to the surface of a gold wire in succession and its wire is dried. C12H25-O-(C2H4O)10-H, C3H7-CO-(C2H4O)12-H, and C7H15-O-(C2H4O)8-H or the like are used as the above activators. Further, it is desirable to apply the activators to the thickness of 20Angstrom -0.5mum. As wire scraping quantities are lessened drastically in stitch bonding as well as in ball bonding, the quantity of gold that is still in existence on the surface of a capillary is lessened exceedingly. The quantity of substances that are attached to the capillary by allowing gold to be alloyed with spark are reduced extremely.

Title: Improvement of dispersibility of fine silicon nitride particle
Inventor: NAGASAKA NOBUYOSHI
IPC: C01B21/068
Filed: 1983-06-25
Abstract: PURPOSE:To improve the dispersibility of the Si3N4 particles and to measure very exactly the shape and size in a simple and rapid manner by treating the surfaces of the Si3N4 particles with a silylating agent. CONSTITUTION:The surfaces of fine Si3N4 particles are treated with a silylating agent such as trimethylchlorosilant to improve the dispersibility. When fine Si3N4 particles are used as a starting material for ceramics, conditions during use and the physical properties of a product depend largely on the shape, average particle size and particle size distribution of the particles. Conventional measurement of shape, size, etc. is carried out after putting fine Si3N4 particles in an org. solvent such as acetone and dispersing them with an ultrasonic cleaner. The shape, size, etc. of each of the particles can not be measured exactly by the method because the particles are not well dispersed. In this invention, the surfaces of fine Si3N4 particles are made nonpolar by treatment with a silylating agent, so the coagulating power among the particles is reduced, and the dispersibility can be improved.

Title: Forming method of semiconductor crystallized film
Inventor: YAMAGUCHI NORITOSHI
IPC: H01L21/20
Filed: 1990-04-28
Abstract: PURPOSE:To reduce the taking-in of oxygen atoms into an amorphous or polycrystalline semiconductor film when the semiconductor film is melted and solidified by applying laser beams so that the upper layer section of the semiconductor film is melted but a lower section is not melted, CONSTITUTION:A foundation layer 2, an amorphous or polycrystalline semiconductor film 3 and a protective film 4 are formed successively on a substrate l, laser beams R are applied from the upper section of the film 14, and the film 3 is crystallized and a crystallized film 5 is formed. Beams R are applied under the state, in which the lower layer section of the film 3 is not melted, by properly adjusting the thickness of the film 3, the intensity of laser beams and the scanning speed of laser beams at that time. Consequently, the constituent elements of a silicon oxide film (the layer 2) shaped to the lower layer of the film 3 is not mixed into the film 5, and oxygen atoms in the film 5 are reduced only by approximately one figure. Accordingly, since no impurity mixes to the film 5 from the layer 2, the speed of response can be increased when a transistor is formed by the film 5 while a back channel can be prevented effective1y when the surface sections of the film 4 and the film 5 are removed partially and the thin-film transistor is formed.
