Title: Bonding wire inspecting device
Inventor: SUGAWARA KENJI
IPC: H01L21/66
Filed: 1991-10-29
Abstract: PURPOSE:To clearly take the pictures of bonded wires, ball sections on a pad, and crescents on leads so that they can be highly reliably inspected and measured by turning on and off a vertical and ring-like lighting means depending upon objects to be inspected and measured. CONSTITUTION:At the time of inspecting a ball section 5a, the optical axis 12a of a CCD camera 12 is aligned with a wire 5A by driving an X-Y table 14 and only a vertical lighting means is turned on by turning off a ring-like lighting means 30. The ball section 5a is vertically irradiated with the light of an electric lamp incorporated in the means 20 through a condenser leans 23 and half mirror 22. Most of the light made incident to the surface of a pad 2 around the section 5a is irregularly reflected, since the pad 2 is made of vapor-deposited aluminum, but, on the contrary, little of the light made incident to the surface of the section 5a is irregularly reflected, since the section 5a is made of gold and has a mirror surface. Therefore, the picture of the section 5a is clearly taken with the CCD camera 12 and the section 5a can be highly reliably inspected and measured.

Title: Insulating film forming method
Inventor: MIYAZAKI YOSHIHISA
IPC: H01L21/31
Filed: 1991-11-25
Abstract: PURPOSE:To form a reproducible insulating film by a method wherein, after the insulating film has been formed by a CVD method, the quantity of carbon and hydrogen contained in the insulating film is decreased. CONSTITUTION:A susceptor 7, with which a wafer 6 is retained facing downward on the upper part of a dispersion head 5 which uniformly disperses the raw gas sent from an ozone feeding device 2 and a TEOS feeding device 3, is provided in a reaction chamber 1. After an insulating film has been formed in the above-mentioned devide by a CVD method using ozone and organic silane, the insulating film is retained in an ozone atmosphere at 150 to 250 deg.C for a specific time, and an anealing treatment is conducted. The above-mentioned temperature of 150 to 250 deg.C is the temperature in the cooling-down course after formation of the insulating film. According to this film-forming method, the amount of the carbon and hydrogen in the insulating film can be reduced by the oxygen atoms generated by the decomposition of ozone.

Title: Semiconductor device, manufacture thereof and conductive ball mounting method
Inventor: WATANABE MASAKO
IPC: H05K3/34
Filed: 1997-10-23
Abstract: PROBLEM TO BE SOLVED: To avoid problems, i.e., positional shift of solder ball at the time of reflow and defective bonding, when solder balls are mounted in a BGA package. SOLUTION: This semiconductor device comprises an insulating board 3 having a plurality of via holes 3a for exposing a part of a conductor pattern formed on one surface to the other side face thereof. A connection terminal, i.e., a conductive ball 7b is bonded to the conductor pattern through a conductive paste 7a filling the via hole 3a. Since the conductive paste 7a has a melting point higher than the that of conductive ball 7b, the conductive ball 7b begins to fuse earlier than the conductive paste 7a, and then the conductive paste 7a begins to fuse after a time lag. Gas generated through boiling of flux in the conductive paste 7a passes through already molten conductive balls 7b and discharged to the outside, thus avoiding positional shift of solder ball and defective bonding.

Abstract: PROBLEM TO BE SOLVED: To provide a cross connect switch where a signal propagation delay is very small so as to realize a small sized cross connector of a large capacity. SOLUTION: Input data (input frame) are sequentially stored in a memory 1 in the unit of time slots. A counter 3 counts the number of input pulses of a clock (a) which is synchronized with the time slot of the input frame, and then outputs the count to the memory 1 as a write address and outputs the count to a memory 2 as a read address. A processor in a cross connector writes data that denotes time slot exchange information in the memory 2 in advance. The memory 2 outputs data stored in the address received from the counter 3 to the memory 1 as the read address. The memory 1 outputs data of the time slot of the input frame stored in the write address as the time slot data of an output frame.
