Title: Semiconductor package
Inventor: TAMURA NARITAKA
IPC: H01L23/50
Filed: 1988-12-14
Abstract: PURPOSE:To improve the bonding strength of lead pins and to make it possible to obtain a highly reliable semiconductor package by a method wherein through holes are formed in parts to exclude the bonding positions of the lead pins. CONSTITUTION:Through holes 5 for internal wiring use are formed in the interior of a ceramics substrate 2. Moreover, lead pads 6 are formed on the surface to oppose to the surface, on which an element is mounted, of the substrate 2 in such a way that the formation positions of the holes 5 and the bonding positions of lead pins 8 are not superposed on each other and the pins 8 are soldered on these pads 2 using a silver solder 7. As the pins 8 are bonded to parts to exclude the formation positions of the holes 5, the effect of the malformation of the holes 5 and the pads 6, which is generated at the time of firing, is never exerted up to the bonding positions of the pins 8 and the bonding positions of the pins 8 are stabilized. Thereby, with the bonding strength of the pins 8 improved, a multitude of the lead pins can be bonded in a uniform state.

IPC: G06F9/32
Filed: 1990-11-20
Abstract: PURPOSE:To omit the programming limitation and the undesired exceptional processing control operations for the design of a hardware by preventing the generation of timing for the undesired hardware stack accesses in a state restoring state. CONSTITUTION:A hardware stack 108 is generally used for the state preserving/ restoring purposes in the call of a subroutine, the interruption, and the exceptional processing in addition to the loop processing. However no trouble occurs even if the instructions (a subroutine call instruction, a restoration instruction and a loop instruction) using the stack 108 overlap with each other in a relevant period since a loop processing hardware stack 130 is separated from the stack 108. Furthermore since the end of the loop, can be carried out with one, the generation of the end of the continuous loop is also permitted. In other words, the program description is never limited in regard of the end of the loop.

IPC: G11B7/257
Filed: 1990-11-20
Abstract: PURPOSE:To obtain same film characteristics under constant film forming conditions by a method wherein an Al-Si target is manufactured by a cast alloy method. CONSTITUTION:In order to manufacture an Al-Si alloy target, a cast alloy method is employed. First, 70 at.% of Si is put into a crucible and heated to 1500 deg.C in a vacuum melting furnace and then 30 at.% of Al is put into the crucible and Al and Si are naturally mixed under a constant temperature of 1500 deg.C and cast into a mold. At that time, crystal grains are distributed uniformly over the whole surface and, moreover, as the target is made of cast alloy, the density is 100%, which is very convenient for sputtering. With this constitution, the same film characteristics can be obtained under constant film forming conditions and density unevenness and variation can be avoided.
