Title: Integrated circuit package and packaging method for same, and deciding method for lead shape and computing method for lead deformation tolerance
Inventor: KIMURA TOSHIFUMI
IPC: H01L23/50
Filed: 1993-02-24
Abstract: PURPOSE:To stabilize the normal contact state by a method wherein the lead deforming process by the contact operation between the lead and a pad is computed in the state wherein the rear surface of a package is bonded onto a printed substrate so that the lead shape making a specific angle of the pad with the lead junction surface may be decided. CONSTITUTION:Within the title lead deformation tolerance computing method, a lead as a cantilever having the side of a package body as a supporting part is to be successively deformed since the lead end previously making an angle of about +70 deg. with a pad is brought into contact with the pad so as to compute the press down amount K1 as the lead deformation amount when the angle of the lead junction surface made with the pad is leveled with the pad (53-55). Furthermore, the heel part of the lead is pushed upward so as to compute the pushed, up amount K2 when the lead junction surface is paralleled with the pad surface (56-58). Finally, this position is further pushed upward so as to compute the pushed up amount K3 when the angle of the lead junction surface made with the pad becomes -7 deg. (59-61) thereby enabling the lead deformation tolerance to be computed by the following formula i.e. z=(K+(k2+3)).

Title: Heat treatment of semiconductor substrate
Inventor: SUZUKI TOSHIHARU
IPC: H01L21/322
Filed: 1980-03-19
Abstract: PURPOSE:To eliminate the stacking fault under short-time heat treatment by acid treating an Si wafer before heat oxidation process under Ar gas of a certain O2 and HCl concentration. CONSTITUTION:Before the heat oxidation process, heat treatment is applied to single crystal Si wafer under Ar gas with controlled O2 concentration of over 6,000ppm and HCl concentration of 1.5-4.0%. Then, oxidized film is formed on the surface of Si wafer by exercising high temperature treatment under oxidation atmosphere. This eliminates the stacking fault. That is, by supplying Ar instead of O2 during HCl oxidation, therefore decreasing O2/Ar ratio and relatively increasing HCl/O2 ratio, the stacking fault can be eliminated from the start and also the causes of stacking fault can be eliminated.

Title: Circuit for preventing character quivering in video circuit

Abstract: PURPOSE:To always display a character such as a track number at the same location without longitudinal quivering by providing a monostable multivibrator circuit and counting a horizontal synchronizing signal in a composite synchronizing signal based on the time point of the end of its operation. CONSTITUTION:When an integration circuit 10 detects a vertical synchronizing signal V.Sync based on a composite synchronizing signal C.Sync in a 0.5H delay period, the signal is taken in a character generation IC9. On the other hand, the monostable multivibrator 13 is triggered on the leading edge of the timing t1 to turn on a transistor (TR) 14. Then even when the signal H.Sync is to be taken in the IC9 by inverting the signal C.Sync by the TR 11, the signal is given to the ground side by the TR 14 and only a pulse of nearly 8H is given. Then the monostable multivibrator 13 is turned off and the TR 14 is turned off, then the signal H.Sync is outputted sequentially to the IC 9. Then the signal H.Sync is counted, based on the operating end timing t2 of the monostable multivibrator 13 to decide the character display position, then the counting of a noise pulse A as 1H is avoided.
