摘要:
A plurality of multi-layer metal plates (1) each being composed of a bump forming metal layer (2), an etching stop layer (3), and a wiring film forming metal layer (4), and in which a wiring film (4a) is formed from the wiring film forming metal layer and a bump 2a is formed from the bump forming metal layer are prepared, and on a bump forming surface of a multi-layer metal plate, a wiring film of another multi-layer metal plate is overlapped. Such lamination process is repeated in succession for multi-layering. In addition, a polishing machine for multi-layer wiring board (11a) which includes metal plate holding means (13) for holding a metal plate (1a), cutter holding means (25) for holding a cutter (26) above the metal plate, height adjustment mechanism (20) for adjusting the height of the cutter holding means, and cutter parallel moving mechanism (15) for relatively moving the cutter holding means in parallel to the surface of the metal plate is used to conduct polishing.

An interconnect element is provided. A monolithic dielectric element has a first exposed major surface, a plurality of first recesses extending inwardly from the first major surface, and a second exposed major surface remote from the first major surface, a plurality of second recesses extending inwardly from the second major surface. A plurality of first metal interconnect patterns are embedded in the plurality of first recesses and extend in one or more directions along the first major surface. A plurality of second metal interconnect patterns are embedded in the plurality of second recesses and extend in one or more directions along the second major surface. A plurality of non-hollow metal posts extend through the dielectric element between at least some of the plurality of first metal interconnect patterns and at least some of the plurality of second metal interconnect patterns.

A multilayer interconnect element is provided which includes at least one dielectric element in which metal interconnect patterns are exposed at an outer surface thereof, the metal interconnect patterns having outer surfaces which are co-planar with an exposed outer surface of the dielectric element. In addition, multilayer interconnect elements are provided in which second interconnect elements which do not have co-planar interconnect patterns are integrated therewith as intermediate elements, and the resulting multilayer interconnect element has co-planar interconnect patterns.

摘要:
An interconnect element is provided which includes a dielectric element having a major surface. Metal interconnect patterns are embedded in recesses which extend inwardly from the major surface, the outer surfaces of the interconnect patterns being substantially co-planar with the major surface and extending in one or more directions of the major surface. A projecting conductive film extends over the major surface in at least one direction parallel to a plane defined by the major surface such that it contacts the dielectric element along at least a portion of the major surface and conductively contacts an outer surface of at least one of the metal interconnect patterns.

An apparatus and method are provided for processing an item by distributing a liquid onto a surface of the item. The apparatus includes a conveyor which defines an undulating path which varies in vertical position relative to the direction of movement of the item conveyable along the path. Thus, the path has at least one apex at a location of the path higher than other locations in the direction of movement along the path. A sprayer is operable to spray the liquid onto the surface of the item at a location that is substantially aligned to the apex of the path.
摘要:
Methods are provided for manufacturing a wiring circuit element or wiring board in which a set of rough wiring patterns are formed by selectively etching a metal layer of a patternable member which includes a carrier layer having a rough surface and a thin rough-surfaced etch stop layer between the carrier layer and the metal layer. The etch stop layer and wiring patterns are joined to an insulating layer such that the wiring patterns adhere to the insulating layer and the insulating layer acquires a rough surface. Thereafter, the carrier layer and the etch stop layer are removed, after which openings are formed in the insulating layer in contact with at least some of the wiring patterns. A layer of metal is electrolessly plated onto the rough major surface of the insulating layer, and then a conductive wiring pattern is selectively electroplated over the electrolessly plated layer to form plated openings that interconnect at least some of the wiring patterns.
