Abstract: A vertical interconnect (15) in an electronic device (10) is manufactured non-photolithographically. This is done by modifying a surface (20,30) of either a metal layer (3) or an intermediate layer of an electrically insulating material (21), and subsequently depositing a composition with a first and a second polymer. Phase separation of the two polymers will lead to a first (6) and a second sub-layer (7), of which the first sub-layer (6) is removed. An upper layer (9) of electrically conducting material can be deposited then or after a further etching step. This results in the vertical interconnect (15).

Abstract: In the method of manufacturing a circular optical storage disc (10), an extension body (21) is present around the substrate (11) of the optical disc (10) during the spin coating of cover or spacer layers (15). The extension body (21) may consist of one or several pieces. The outer periphery (23) has a circular or polygonal shape. The inner periphery of the extension body is in close circumferential contact with the periphery (13) of the optical disc substrate (11). The surface (22) of the extension body is substantially flush with the surface (12) of the substrate (11) of the optical disc in order not to impede the flow of spin coating liquid during spin coating. The raised edge (16), which usually forms at the periphery (13) of the substrate (11) is now transferred to the outer periphery (23) of the extension body (21). After the coating operation the extension body (21) is removed. By choosing a surface (22) to which the coating (15) adheres poorly, reuse of the extension body (21) is facilitated.

Abstract: A method of providing a track (12) on a substrate (10) includes a first step wherein a first liquid (1) is applied to the substrate (10) in accordance with a desired double pattern (11) and, upon solidification of said first liquid, a second step wherein a second liquid (2) is applied within the double pattern (11), forming the track (12) upon solidification. The double pattern (11) laterally bounds the track (12). The liquids (1, 2) may be applied by a dispenser or an ink jet printer. The first and the second step may be carried out in one operation, wherein the application of the first liquid (1) has a lead (3) over the application of the second liquid (2). A narrow track (12) may be formed when the first liquid (1) has a head group that adheres to the substrate (10) and a tail that repels the second liquid (2).
