Abstract:
A laminate substrate for receiving a semiconductor chip. Included are laminate layers stacked to form the laminate substrate, each laminate layer includes a core that includes particle-filled epoxy and a metallic layer on the core. At least one laminate layer has a radial cut through the metallic layer, the radial cut extending from a periphery of the at least one laminate layer towards a center of the at least one laminate layer. The radial cut cuts only through the metallic layer and does not cut through the core.
Abstract:
A transparent conductive film comprises a transparent substrate and a metal wiring portion formed thereon. A thin metal wire contained in an electrode portion in the metal wiring portion has a surface shape satisfying the condition of Ra2/Sm>0.01 μm and has a metal volume content of 35% or more. Ra represents an arithmetic average roughness in micrometers and is equal to or smaller than the thickness of a metal wiring located in a position where the surface roughness is measured. Sm represents an average distance between convex portions and is 0.01 μm or more.
Abstract:
A method of making an imprinted micro-wire structure includes providing a substrate having an edge area and a central area separate from the edge area and providing first, second, and third different stamps. A curable bottom, connecting layer, and top layer are formed on the substrate. A bottom-layer micro-channel is imprinted in the bottom layer in the central area and the edge area, a connecting-layer micro-channel is imprinted in the connecting layer in the edge area over the bottom-layer micro-channel, an edge micro-channel is imprinted in the top layer in the edge area over the connecting-layer micro-channel, and top-layer micro-channels are imprinted in the top layer over the central area. Micro-wires are formed in each micro-channel. The bottom-layer micro-wire in the central area is electrically connected to the edge micro-wire in the edge area and is electrically isolated from the top-layer micro-wire.
Abstract:
A method of making an imprinted micro-wire structure includes providing a substrate, a first stamp, and a different multi-level second stamp. A curable bottom layer is provided over the substrate. One or more bottom-layer micro-channel(s) are imprinted in the curable bottom layer with the first stamp and a bottom-layer micro-wire formed in each bottom-layer micro-channel. A curable multi-layer is formed adjacent to and in contact with the cured bottom layer. First and second multi-layer micro-channels and a top-layer micro-channel are imprinted in the curable multi-layer with the multi-level second stamp. Either two bottom-layer micro-wires are electrically connected through the first and second multi-layer micro-wires and a top-layer micro-wire or two top-layer micro-wires are electrically connected through the first and second multi-layer micro-wires and a bottom-layer micro-wire.

The bottom-layer micro-wire extends from the central area into the edge area. The multi-layer micro-wire contacts the bottom-layer micro-wire in the edge area. The top-layer micro-wire is over the central area and is separate from the multi-layer micro-wire and the bottom-layer micro-channel. The bottom-layer micro-wire is electrically connected to the multi-layer micro-wire and is electrically isolated from the top-layer micro-wire.
Abstract:
A wiring board includes a base in which plate wirings formed of a metal plate are integrally formed with an insulating portion made of resin or a resin composition and surface wirings electrically connected to the plate wirings. The base has first and second surfaces on which the surface wirings are formed. The surface wirings are thinner than the plate wirings, and the minimum wiring gap between the surface wirings is smaller than the minimum wiring gap between the plate wirings. One of the plate wirings has substantially the same shape as that of a region where the first top-surface wiring on the first surface and the first bottom-surface wiring on the second surface overlap with each other in the normal direction of the first surface. The first top-surface wiring and the first bottom-surface wiring are connected to each other through the above-mentioned one of the plate wirings.
