    摘要: A modular multilayer interwiring structure comprising a plurality of relatively small parts which are produced separately as `sub-units` (1). Each individual layer of the final structure is formed by joining a respective set of unit parts in one plane. The whole multilayer structure is then built by stacking these layers, preferably so that the units of one layer are not vertically aligned with the units of an adjacent layer. Each unit part includes at least one layer of conductive material (8, 9) on its front and/or rearside. These conductive layers may be individually patterned into diverse interconnection lines (5). Throughconnections (6) extending from the frontside to the backside of the units are provided using a desired set or a standardized array of via holes or openings filled with conductive material. By connecting desired throughconnections to the respective conduction lines, each unit may form an individual part of a more complex multilayer interwiring structure.

    摘要: The contact probe arrangement includes a stack of perforated plates (1, 1a) through which extend a plurality contact probes. The stack of perforated plates consists of two kinds of plates. The first kind forms the lowermost plates (1a). They have circular or square holes permitting a vertical placing of the contact probes onto the contact pads (4) of the device (5) to be tested. The plates (1) of the second kind have oblong, rectangular, square, circular, elliptical or trapezoidal holes (3). With respect to the stacked plates of the second kind, alternate ones are offset against the two other adjacent plates which are aligned relative to each other, in such a manner that each contact probe is surrounded by part of the lower edge of the upper of two adjacent perforated plates, and part of the upper edge of the lower of two adjacent perforated plates. If axial stress is applied, the contact probe can thus not buckle any farther than to a part of the perforation wall limiting its maximum buckling. This ensures a sufficiently low contact resistance between the contact probe and the contact pad of the device to be tested. By using a corresponding number of perforated plates of the second kind the contact probes can adapt to height differences of the contact pads caused by irregularities in the surface of the device to be tested.

    摘要: An optical storage disk includes a glass substrate (1) into which guide tracks (3) for servo-controlling the focussed light beams are directly stamped in by hot stamp process. After stamping, the glass substrate is thermally quenched in the stamping device to increase its breaking resistance through thermal curing. In order to achieve uniform guide tracks over the entire surface of an optical storage disk, flexible stamp stencils (35) in a flexible holder (34) are used whose curvature can be changed by applying hydro-static pressure. Suitable stamp stencils include monocristalline silicon disks with surface hardening, or of metal disks, structured photolithographic processes. The stamp lands are made with bevelled edges to facilitate the separating of stamp and glass substrate after cooling.
