Inventor: FURANSHISU JIEI KAANII
IPC: H01L21/60
Filed: 1993-02-26
Abstract: PURPOSE: To connect leads of a leads frame to a semiconductor device by taking advantage of a substantially coarse surface of a bond pad, compared with a surface of a lead of the lead frame to thereby significantly suppress the formation of bumps and hence to increase adhesion strength. CONSTITUTION: A semiconductor device includes a semiconductor die 22 on the suface, of which a plurality of bond pads 28 are arranged. A lead frame having a plurality of lead parts 24 is connected to the bond pads 28. Surface of each bond pad 28 is substantially coarser than that or the lead part 24. As a result, stronger adhesion can be achieved between the lead 24 and the bond pad 28, with the additional advantage of a sharp reduction in bumps. That is, the substantially coarse surfaces of the bond pads 28 permit superior adhesion to the leads 24.

Title: System for displaying file system with tree structure
Inventor: FUJIOKA TAKU
IPC: G06F12/00
Filed: 1987-03-17
Abstract: PURPOSE:To efficiently display the latest tree structure figure without hiding other display objects, by generating and displaying only a part required for the tree structure figure at an arbitrary position on a display by the indication of a pointing device. CONSTITUTION:When the indication of display is issued by the pointing device 4, a position detecting part 22 detects the position of a cursor on the display 3 at that time, and a tree structure figure generating part 21 generates partial figures of the elements of levels corresponding to the main masters of the tree structure from an information storing part 1, and displays them at the position of the cursor. Following that, when the element at the position of the cursor has a slave element at a lower level, the slave elements are displayed adjacently to the element, and when no slave element exists, no display is performed. In such a way, since the required part of a tree structure file system is displayed dynamically, it is possible to display the tree structure without bothering other display objects on the display.

Filed: 1989-03-14
Abstract: PURPOSE:To prevent the deterioration in high frequency characteristics of an element by constituting a protecting film on an HEMT that is an active element with one-layer insulating film. CONSTITUTION:This circuit is composed of the following parts: an HEMT 1 that is an active element; wirings 2; a capacitance 3; ohmic metals 4; an insulating film 5 that is a protective film; a nitride film 6; and a GaAs substrate 7. The active element is not limited to the HEMT, but any material having an amplifying function can be used. For examples, amplifying elements comprising bipolar transistors and FETs can be used. GaAs is used for the substrate, but it is a matter of course that other high dielectric constant material or Si can be used.

Title: Die for cold forging
Inventor: OGAWA MASUJI
IPC: B21K1/44
Filed: 1982-04-14
Abstract: PURPOSE:To prevent breaking-off of a formed piece, by forming a relief face at an intersection of the inner face of a formed piece and a contact face so as to remove the corner. CONSTITUTION:When forging, pressure is applied outward in the forming hole, and this pressure becomes maximum at the center of each side of a hexagon. Consequently, the inside face 20a of each formed piece 20 is deformed to bent outward. Since a relief face 20d is formed, an intersection of inside face 20a and the relief face 20d does not collide with adjoining formed pieces 20. Accordingly, the formed piece 20 is hard to be broken. It is enough to form the relief face only in one of the adjoining formed pieces 20.
