Title: Sputtering apparatus
Inventor: SERIKAWA TADASHI
IPC: H01L21/302
Filed: 1983-11-26
Abstract: PURPOSE:To raise sputter etching rate of thin film during bias sputtering and also improve thin film characteristic by providing a magnet which has magnetic field component parallel to a substrate and a means for applying a negative voltage or a high frequency voltage to the surface of substrate. CONSTITUTION:A magnet 58 which has field component parallel to the surface of substrate 57 is provided to the rear surface of substrate pedestal. A pole piece 59 is also provided for efficiently applying the magnetic field to the substrate surface. Under this condition, a thin film is formed while a negative voltage or high frequency voltage is applied to the substrate pedestal. Thereby the bias sputtering can be realized. When a negative voltage is applied to the substrate surface, the field vertical to the substrate surface is generated, very high density plasma is generated at the area near the substrate surface by such field and magnetic field parallel to the substrate surface. As a result, sputter etching rate becomes very high and particularly it becomes distinctive in the region where the magnetic field is parallel to the substrate surface. Magnets must be disposed in such a direction as the opposite magnetic pole in such a way as surrounding the center magnet in order to stabilize the high density plasma at the area near the substrate surface.

Title: Inching mechanism for scanning tunnel electron microscope
Inventor: TAKADA RYUJI
IPC: H01J37/28
Filed: 1992-07-30
Abstract: PURPOSE:To prevent displacement by providing a prove, a piezoelectric element, and coupling members having different stiffnesses in different directions thereby preventing adverse effect in two remaining directions when one of three piezoelectric elements elongates or contracts to move a probe in one direction. CONSTITUTION:Coupling members 10A, 10B, 10C have high stiffness in X, Y, and Z directions, respectively, and low stiffness in Y, Z; X, Z; and X, Y directions. When a piezoelectric element 2C elongates in Z direction, a member IC having high stiffness in Z direction transmits elongating force of the element 2C accurately to a supporting member 8 and a probe 3. Consequently, the probe 3 moves accurately in Z direction. On the contrary, displacement of the probe 3 in X, Y direction scarcely causes displacement of the members 10A, 10B in X, Y direction. Since the tip of the probe 3 is displaced only in Z direction through elongation of the element 2C, it can be inched accurately in the height direction when viewed from the axial direction or the irregularities on the measuring surface of a sample. Similar function is achieved for the members 10A, 10B with regard to elongation of the elements 2A, 2B.

Title: Semiconductor device
Inventor: YOSHIDA MIYOSHI
IPC: H01L21/60
Filed: 1984-10-22
Abstract: PURPOSE:To prevent damages caused by temperature variation by sticking the wiring substrate as the center part of its lower surface and the bottom of the package are joined with an adhesive agent. CONSTITUTION:On the upper surface of the wiring substrate 3, several semiconductor chips 1 are fixed with the bumps 2, and the lower central part of the substrate are stuck with the central part of the bottom surface of the package 11 with an adhesive agent 13 like epoxy resin. The wiring of this wiring substate 3 and the interval wiring 7 of the package 11 are connected by the wire bonding. Although the pressure load is impressed from above on the peripheral part of the wiring substrate 3 in this wire bonding process, damages are prevented as the lower surface is supported with the projection part 12. As the wiring substrate 3 is stuck only with the central part of the lower surface, the restriction concerning thermal expansion is not so serious that the damages caused by thermal stress are avoided. These facts apply to the large sized wiring substrate 3 loaded with the more number of semiconductor chips 1.

Abstract: PURPOSE:To realize a polygonal line approximating system which can produce a faithful approximate diagram without drawing a linear graphic form with fine lines, by extracting bending lines from all contours of the linear graphic form having a width and finding a real feature point by combining the bending lines. CONSTITUTION:Videos inputted from a picture input device 1 are stored in a picture memory 2 after binary coding. A linear graphic form is segmented from the content of the picture memory 2 through a command from an address control section 6. At a bending point extracting circuit 3 the 3rd stage processing is performed and bending points are extracted. At the 1st stage processing a contour list is produced by tracing the contour of the linear graphic form, and then, the linear graphic form is regarded as a virtual closed domain by connecting the starting point with ending point of the graphic form. At the 2nd stage, a connecting code which shows a rough direction is added to the contour of the virtual closed domain by using a window and an inclining code is produced. At the 3rd stage, bending points are extracted from the connecting and inclining code lists. A bending point integration circuit 4 performs vector arithmetic based on the found bending points and extracts feature points. A display device of approximate graphic form of polygonal line 5 displays a graphic form from the feature points.
