Patent ID: 7541058

Claim:
A method of making a circuitized substrate including at least one optical pathway therein, said method comprising: providing a dielectric layer; forming an electrically conductive layer on said dielectric layer; laminating a cladding layer to said electrically conductive layer, having a predetermined refractive index, atop said electrically conductive layer, said cladding layer having an upper surface and a lower surface; aligning a stencil comprising a tapered opening therein over said cladding layer; depositing material within said tapered opening and pressing said material therethrough, squeezing said material to substantially fill said opening; removing said stencil; depositing a reflective layer having an angular configuration onto said material, covering the sides and top of said material; and depositing an optical core layer comprising highly optically conductive material onto said reflective layer such that optical signals passing through said optical core will be reflected off said angular reflector and pass through said opening.
