Abstract
A method of forming a metallic feature on a substrate, comprising the steps of: providing a stamp having a raised region; depositing catalytic particles on a selected area of the stamp, including the raised region thereof; providing a substrate; applying the stamp to the substrate, such that the raised region of the stamp causes a corresponding indented region in the substrate and at least some of the catalytic particles are transferred to a selected area of the substrate; and plating the selected area of the substrate.

A method of forming a metallic feature on a substrate, comprising the steps of:
- providing a stamp having a raised region;
- depositing catalytic particles on a selected area of the stamp, including the raised region thereof;
- providing a substrate;
- applying the stamp to the substrate, such that the raised region of the stamp causes a corresponding indented region in the substrate and at least some of the catalytic particles are transferred to a selected area of the substrate;
- and
- plating the selected area of the substrate.
A method of forming a metallic feature on a substrate, comprising the steps of:
- providing a mould, an inner surface thereof having a raised region, depositing catalytic particles on a selected area of the inner surface of the mould, including the raised region thereof;
- providing a substrate material;
- moulding the substrate material within the mould, such that a resulting substrate has an indented region corresponding to the raised region of the inner surface of the mould and at least some of the catalytic particles are transferred to a selected area of the substrate;
- and
- plating the selected area of the substrate.
A method of forming a metallic feature on a substrate, comprising the steps of:
- providing a stamp;
- depositing polymer-stabilised catalytic particles on a selected area of the stamp;
- providing a substrate;
- applying the stamp to the substrate such that at least some of the polymer-stabilised catalytic particles are transferred to a selected area of the substrate;
- and
- plating the selected area of the substrate.
A stamp for application to a substrate, having a selected area comprising a raised region on a surface thereof and at least the selected area of the surface having catalytic particles deposited thereon.
A stamp for application to a substrate, comprising polymer-stabilised catalytic particles deposited on a selected area of a surface thereof.
An apparatus for preparing a substrate, comprising:
- a stamp having a selected area comprising a raised region on a surface thereof and at least the selected area of the surface having catalytic particles deposited thereon;
- and
- means to apply the stamp to a substrate.
An apparatus for preparing a substrate, comprising:
- a stamp comprising polymer-stabilised catalytic particles deposited on a selected area of a surface thereof;
- and
- means to apply the stamp to a substrate.
