A microstructure forming method includes a step A of irradiating a region of a substrate, in which a hole-shaped or groove-shaped microstructure is to be formed, with a circularly or elliptically polarized laser beam having a pulse width of which the pulse duration is on the order of picoseconds or shorter, and scanning a focal point at which the laser beam converges to form a modified region, and a step B of performing an etching process on the substrate in which the modified region is formed and removing the modified region to form a microstructure.

The invention is directed to a method of providing a plastic substrate (1) with a metallic pattern (8) and to a plastic substrate (1) with a metallic pattern (8) obtainable by said method. The method of the invention comprises i) replicating a pattern of recesses and protrusions on a plastic substrate (1) by pressing a stamp having recesses and protrusions against the substrate, thereby providing said plastic substrate (1) with recesses and protrusions; ii) removing said stamp from said substrate; iii) - providing a layer of seed material (2) capable of initiating an electroless or electrochemical metal deposition process onto said plastic substrate at least in the recesses of said plastic substrate; - optionally providing a layer of inhibitor material on top of or below said layer of seed material (2); and - if necessary, etching excess seed material (2) and/or excess inhibitor material (3), to yield a substrate wherein said seed material (2) and/or said inhibitor material (3) remains selectively in the recesses or on the protrusions of said substrate; and thereafter iv) using said seed material (2) to initiate a metal deposition process.
摘要:
A method of manufacturing an opto-electric hybrid board which is capable of reducing the number of steps for the manufacture of the opto-electric hybrid board and which achieves the reduction in thickness of the opto-electric hybrid board to be manufactured, and an opto-electric hybrid board obtained thereby. A resist layer (4) is formed on a core-forming resin layer (3a), and is then formed into a predetermined pattern. Resultant portions of the core-forming resin layer serve as cores (optical interconnect lines) (3). Next, a thin metal film (5) is formed on the under cladding layer (2) so as to cover the resist layer and the cores (3). Thereafter, the resist layer (4) is removed together with portions of the thin metal film (5) lying on the surface of the resist layer. Electroplating is performed on the remaining portions of the thin metal film (5) to fill grooves (6) defined between adjacent ones of the cores (3) with electroplated layers (7a) obtained by the electroplating. The electroplated layers (7a) serve as electrical interconnect lines (7).

A method of manufacturing an opto-electric hybrid board which is capable of reducing the number of steps for the manufacture of the opto-electric hybrid board and which achieves the reduction in thickness of theopto-electric hybrid board to be manufactured, and an opto-electric hybrid board obtained thereby. A plurality of protruding cores (optical interconnect lines) (3) are formed in a predetermined pattern on a base (1) and under cladding layer (2). Thereafter, a thin metal film (4) is formed in grooves defined between adjacent ones of the cores (3). Via-filling plating is performed on the thin metal film (4) to fill the above-mentioned grooves with a via-filling plated layer (6a). The plated layer (6a) serves as electrical interconnect lines (6). An over cladding layer (7) is formed to cover the cores (3) and electrical interconnect lines (6).
