A monitoring apparatus is provided with an imaging section which can partially pick up an image of a wafer (10). The monitoring apparatus monitors the surface of the wafer (10) by using partial images (A, A and so on) of the wafer (10) in a plurality of imaging regions. The partial images are obtained by picking up the images of a plurality of parts of the wafer (10) (an apex section (13)), while relatively moving the imaging region of the imaging section in the circumference direction of the wafer (10). The monitoring apparatus is provided with an image connecting section and an image display section. The image connecting section compresses partial images (A, A and so on) so that each compression ratio in a direction corresponding to the circumference direction of the wafer (10) is larger than that in the direction vertical to such direction, then, the image connecting section connects the partial images to be arranged in the circumference direction to obtain a connected image (B) by which the apex section (13) of the wafer (10) can be continuously visible in the circumference direction. The image display section displays the connected image (B) wherein the partial images are connected by the image connecting section.
摘要:
An adhesive-free multilayered metal laminate having a given thickness which is obtained by bonding a metal sheet having a thin metal film on a surface thereof to a metal foil without using an adhesive; and a process for continuously producing the laminate. The process comprises the steps of; setting a metal sheet on a reel for metal sheet unwinding; setting a metal foil on a reel for metal foil unwinding; unwinding the metal sheet from the metal sheet-unwinding reel and activating a surface of the metal sheet to thereby form a first thin metal film on the metal sheet surface; unwinding the metal foil from the metal foil-unwinding reel and activating a surface of the metal foil to thereby form a second thin metal film on the metal foil surface; and press-bonding the activated surface of the first thin metal film to that of the second thin metal film so that the first thin metal film formed on the metal sheet is in contact with the second thin metal film formed on the metal foil.

A multilayer printed wiring board having a wiring lead-out port has a signal circuit conductor perfectly covered by an earth circuit in its inside and a wiring lead-out port. A signal circuit conductor having a branch pattern is preferable. A large number of products can be easily manufactured with good size reproducibility. The multilayer printed wiring board is manufactured by selectively etching the copper of a cladding sheet manufactured by bonding a copper foil to a nickel foil with 0.1-3 % reduction and forming a signal circuit conductor covered by an earth circuit and the wiring lead-out port.

A clad plate for forming an interposer for a semiconductor device which can be manufactured at low cost and has good characteristics, an interposer for a semiconductor device, and a method of manufacturing them. Copper foil materials (19, 24, 33) forming conductive layers (10, 17, 18) and nickel plating (20, 21) forming etching stopper layers (11, 12) are formed and pressed to form a clad plate (34) for forming an interposer for a semiconductor device. Thus, a clad plate (34) for forming an interposer for a semiconductor device is manufactured. The clad plate (34) is selectively etched to form a columnar conductor (17), and an insulating layer (13) is formed on the copper foil material forming a wiring layer (10). A bump (18) for connection of a semiconductor chip and the wiring layer (10) are formed on the opposite side to the side on which the columnar conductor (17) is formed. Thus, an interposer for a semiconductor device is manufactured.

摘要:
There is disclosed a technology of measuring three-dimensional geometric information on a plane and position information on a point from an image such as the optical flow pattern and a stereo image. It is to determine an azimuth of a measuring plane and/or a superposing time in which the measuring plane is superposed on a predetermined observation point, using a compound ratio {pinfp0p1pc}, which is determined by four positions pinf, p0, p1, pc of a measuring point, where p0 and p1 denote measuring positions at mutually different two measuring times on an arbitrary measuring point appearing on an image obtained through viewing a predetermined measurement space from a predetermined observation point inside the measurement space, respectively, pinf denotes a position of the measuring point after an infinite time elapses, and pc denotes a position of the measuring point at a superposing time in which a measuring plane including the measuring point is superposed on the observation point in the moving continuous state.
