Abstract: A method of anisotropic plasma etching of a substrate material through a window defined in an etching mask comprises the steps of: disposing a hard mask material by injection of a precursor gas or precursor liquid and plasma-activated deposition to form a hard mask layer to form a temporary etch stop on the etching mask; anisotropically plasma etching the hard mask layer by contact with a reactive etching gas to leave a portion of the hard mask layer on vertical walls of the window in the etching mask while exposing at least part of the surface of the substrate; and selectively etching material from the substrate underlying the exposed part of the surface while leaving the portion of the hard mask layer on vertical walls of the window in place.

Abstract: Various embodiment comprise silicon-on-insulator waveguide designs that simultaneously achieve both high optical confinement, low-loss, and provide for electrical connections. In certain embodiments, high index contrast waveguides comprise a central elongate waveguide portion and a segmented portion comprising a single thin layer of Silicon-On-Insulator that achieves both high optical confinement and minimal insertion loss. Other devices, such as chemical and biological sensors, and optical elements may also be fabricated.
