Publication number: 20150346431Abstract: Aspects of the invention are directed to a method for forming an optical waveguide structure. Initially, a base film stack is received with an optical waveguide feature covered by a lower dielectric layer. An etch stop feature is then formed on the lower dielectric layer, and an upper dielectric layer is formed over the etch stop feature. Subsequently, a trench is patterned in the upper dielectric layer and the etch stop feature at least in part by utilizing the etch stop feature as an etch stop. Lastly, a waveguide coupler feature is formed in the trench, at least a portion of the waveguide coupler feature having a refractive index higher than the lower dielectric layer and the upper dielectric layer. The waveguide coupler feature is positioned over at least a portion of the optical waveguide feature but is separated from the optical waveguide feature by a portion of the lower dielectric layer.Type: ApplicationFiled: August 6, 2015Publication date: December 3, 2015Inventors: Russell A.
