Abstract:
A method for providing a vertical optical via for a semiconductor substrate is described. The semiconductor substrate has a front surface and a back side. A hard mask having an aperture therein is formed on the front surface. Part of the semiconductor substrate exposed by the aperture is removed to form a via hole. The via hole has a width not exceeding one hundred micrometers and a bottom. Cladding layer(s) and core layer(s) are provided in the via hole. The core layer(s) have at least a second index of refraction greater than that of the core layer(s). A portion of the semiconductor substrate including the back side is removed to expose a bottom portion of the core layer(s) and a bottom surface of the semiconductor substrate. The vertical optical via includes the cladding and core layers. The vertical optical via extends from the front surface to the bottom surface.

Claim (Index 1):
A method for providing a vertical optical via for a semiconductor substrate having a front surface and a back side, the method comprising:\n forming a hard mask on the front surface of the semiconductor substrate, the hard mask having an aperture therein, a first portion of the semiconductor substrate being exposed by the aperture; removing the first portion of the semiconductor substrate to form a via hole in the semiconductor substrate, the via hole having a bottom and a width of not more than one hundred micrometers; providing at least one cladding layer in the via hole, the at least one cladding layer having at least a first index of refraction; providing at least one core layer in the via hole, the at least one core layer having at least a second index of refraction greater than the at least the first index of refraction; and removing a second portion of the semiconductor substrate including the back side and the bottom of the via hole to expose a bottom portion of the at least one core layer and a bottom surface of the semiconductor substrate, the vertical optical via including the at least one cladding layer and the at least one core layer, the vertical optical via extending from the front surface of the semiconductor substrate to the bottom surface.
