Title: Bonding tool
Inventor: ASADA SHUJI
IPC: H01L21/321
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To provide a bonding tool which has excellent resistance to mechanical shock, wear an thermal shock, has a relatively small weight, has conductivity and is suitable for electric-discharge machining, by causing a component in contact with a wire used in a wire bonding device to be made of ceramics containing titanium nitride and/or titanium carbide-nitride. SOLUTION: Components in contact with a wire, such as, a capillary, a wedge and the like used in a wire bonding device, are mode of ceramics containing titanium nitride and/or titanium carbide-nitride. This nitride and/or carbide-nitride provides conductivity to the bonding tool, thus achieving the shape precision required for enabling electric-discharge machining and also reducing the working cost. In addition, since the titanium nitride or titanium carbide-nitride has a high hardness, it also has a high wear resistance. Uniaxial pressurized shaping is suitable for shaping. Sintering is effective under pressure in a nitrogen atmosphere or in an inert gas atmosphere containing nitrogen.

Title: Processing method of substrate by optically-excited gas decomposition
Inventor: KUGIMIYA KOUICHI
IPC: C23C16/48
Filed: 1984-05-09
Abstract: PURPOSE:To control the flow of a gas made radical or decomposed by optical excitation and a gas for protection and thereby to prevent the deterioration of an optical window by a method wherein a second gas is decomposed by excitation and further made to react with a substrate, and thereafter the decomposed gas and first and second gases are discharged from the back side of the substrate. CONSTITUTION:Pressure difference plates 6 are provided for maintaining a pressure difference in a gas flow channel. A second gas g2 used for processing a substrate 1 is made to flow on the opposite side of these pressure difference plates 6 and further flow down along these plates and is applied uniformly on the substrate 1. In other words, the pressure difference plates 6 are shielding plates operating also for regulating a flow. The second gas g2 flowing down on the substrate 1 is excited by a light 3 passing through an optical window 4, and is thereby made into plasma or decomposed, so as to be activated to react with the substrate. The decomposed gas and first and second gases are discharged from a discharge port 5 provided on the back side of the substrate. In terms of the gas flow channel, accordingly, the pressure is highest on the first gas g1 side and turns lower sequentially toward the substrate side. Moreover, the gas flow is regulated to be in strate by the operation of the shielding plates 6 having the effect of flow regulation, and thus the second gas seldom reaches the surface of the optical window 4.

Abstract: PURPOSE:To reduce the deviation of a control output by detecting and control ling the change of a mechanical characteristic in a galvano-mirror structure in an external circuit and correcting the characteristic in a control means having two cascade connections of fine position control and coarse position control. CONSTITUTION:When a deviation (difference) is present between the mechanically neutral position of the displacement 107 of the fine position control means (the displacement of a galvano-mirror mechanism) and the target position of the servo control 111 (displacement of the coarse position control mechanism), the shift of the neutral position (tracking error signal) 101 is detected before entering in the state of tracking servo control. At the same time the state of track control begins, the difference is calculated for correction by means of a deviation correcting means 3. When the difference between the neutral position of the displacement 107 of the fine position control means and the target position 111 of the servo control system is present or even when the difference varies with time, by continuously or intermittently correcting the deviation correcting means 3, the deviation of the control output is reduced and the variation is suppressed.
