Title: Aluminum ball bonding method
Inventor: KOIZUMI MASAHIRO
IPC: H01L21/603
Filed: 1984-06-13
Abstract: PURPOSE:To obtain a rigid connection even if aluminum wirings are used by controlling the thickness of an aluminum film and the diameter of a ball after bonding. CONSTITUTION:A bonding strength has a correlation with the diameter of a ball after bonding. In other words, when the logarithm 2ln(D/D0) of the value produced by dividing the diameter D0 before bonding by the diameter D of the ball after bonding is a strain, if the strain amount is increased, an area of the ball and the broken oxide film of the film boundary increases. Thus, the bonding strength increases. Accordingly, in order to obtain a connection having high reliability, the bonding may be performed by a method of increasing the strain of bonding. When the thickness of the aluminum film increases, the bonding strength increases. From the above, when the D/D0 is (y) and the thickness of the aluminum is (x), the connection having high reliability can be obtained by controlling the (x) and D so as to become the value of higher obtained by y= 3.32-0.0225x.

Filed: 1980-08-30
Abstract: PURPOSE:To make print for electronic register outputting the print output of an accounting data for on-line and to avoid print for off-line (line failure), by directly coupling the center on on-line and providing a printer. CONSTITUTION:The content of various totalizers by commodity SUMO-SUMN selected with the instruction of a counter CNT is read out at an output buffer BUF1, and the content of the flag section F is compared with an on-line signal SON. The signal SON is at ''1'' in case of on-line (at normal) and the output of an inverter I1 is at ''0'' when the flag is at ''1'' to inhibit the transfer of the data of the output buffer BUF1 to a buffer BUF3. When the flag F is at ''0'' and the signal SON is at ''0'', the output of the inverter I1 is at ''1'', and the data of the buffer BUF1 is transferred to the buffer BUF3 for print. That is, at the normal operation, since it is not required to print all the contents of a number of totalizers, the print time of an electronic register is reduced and the printer paper can be saved.

Title: Reverse-conductivity gate turn-off thyristor device
Inventor: YOTSUDO TAKASHI
IPC: H01L29/74
Filed: 1984-06-12
Abstract: PURPOSE:To prevent erroneous ignition without reducing the area occupied by a GTO region and RCD region by a method wherein a drain region is provided in an isolating region for the expulsion of excessive holes. CONSTITUTION:A drain region 22 belongs to the same P type layer as an RCD anode layer 13' and is shaped when an n<+> layer 23 is formed by selective diffusion. The drain 22 region is set at the same potential as the anode layer 13' due to an anode electrode 19. To stop the p-n-p-n structure created at the lower portion of the n<+> type layer 23 from latchup, the surface of the n<+> type layer 23 is covered by an insulating film 21. It follows therefore that holes out of the excessive carriers forced out of an RCD region (b) into an isolating region (c) are collected by a cathode electrode 16 through the drain region 22, which effectively contributes to the prevention of erroneous ignition. The drain region 22 occupies an area not larger then 20% of the RCD region, and the current present in the drain region 22 is so small as to be less than 1% of the RCD current. This means that the drain region 22 virtually functions only to eliminate excessive holes.
