Abstract: PURPOSE:To provide a button electrode type semiconductor device wherein a stable soldering quality is obtained in its assembling process and a high reliability is obtained in its operational aspect. CONSTITUTION:In a button electrode type semiconductor device, two button type electrodes 2 are so superimposed on both sides of a semiconductor chip 1 having both its surfaces as principal surfaces that the semiconductor chip 1 is interposed between the electrodes 2 and its respective principal surfaces are soldered to the electrodes 2 and further the peripheries of the semiconductor chip 1, the solder and the electrodes 2 are sealed with a resin. In this button electrode type semiconductor device, the button type electrode 2 is stamped while a flat copper plate is used as its raw material. Thereby, the opposite end surface of the electrode 2 to the semiconductor chip 1 is made flat, and the peripheral edge of the stepped part of the electrode 2 is made sharp. As a result, a normal solder fillet is formed between the electrode 2 and the semiconductor chip 1, and a stable soldering quality is obtained.

Inventor: KIRA HIDEHIKO
IPC: H01L21/60
Filed: 1990-09-04
Abstract: PURPOSE:To make possible the improvement of the reliability of a tool for bonding use by a method wherein a TiN film of a prescribed thickness is provided on the tip of a tool main body for bonding use. CONSTITUTION:A TiN film 32 is adhered on the tip of a tool main body 31. This film 32 is formed by sputtering, the thickness (t2) of the film 32 is 2mum and is as thin ad about 1/100 of the thickness of a conventional ceramic film. The film 32 has a nature that repels solder like the ceramic film, the adhesion of a solder to a tool 30 for gang bonding use is not generated and a bonding is performed repeatedly and stable. As the film 32 is 2mum in thickness and is very thin, it can be stretched with comparatively ease. As a result, the film 32 results in being easily following the thermal expansion and shrinkage of the main body 31 and even if the bonding is repeated, the adhesive force of the film 32 in the interface between the film 32 and the tip adhered with the film 32 is not reduced.

Filed: 1990-09-05
Abstract: PURPOSE:To reduce noise at non-signal by detecting the presence of a signal as an input of a noise shaper and stopping a dither function when no signal exists so as to clear the data in the noise shaper. CONSTITUTION:When a detection circuit 30 detects the absence of a digital signal based on an output A of a filter 10, a detection output NS goes to 1 and a control switch 32 is in off-control and a data in a noise shaper 16 is cleared. When the switch 32 is in the off-state, the addition of an AC waveform signal D is stopped by an adder 12, an output A1 of the adder 12 reaches a non-signal state and all the data in the noise shaper 16 are cleared.

An optical path of a photo-interrupter is released, and logic of the output is reversed. The tip of a sheet P enters into a pair of reverse rollers 22, and the back end goes out of the nip of the pair of first discharge rollers 11. The flag 18 recovers its rotational angle due to elasticity or self-weight, and again shields the optical path of the photo-interrupter 17. Thus, the through out of the sheet P from of the nip of a pair of first discharge rollers 11 is detected.
