METHOD OF MAKING SEMICONDUCTOR DEVICE INCLUDING OPTICAL THROUGH VIA AND METHOD OF USING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18358790 titled 'METHOD OF MAKING SEMICONDUCTOR DEVICE INCLUDING OPTICAL THROUGH VIA AND METHOD OF USING
Simplified Explanation
- The patent application describes a method of making a semiconductor device. - The method involves creating an opening in a substrate that extends from one side to the other. - A dielectric material with a specific refractive index is deposited into the opening. - The dielectric material is then etched to create a core opening within it. - A core material with a different refractive index is deposited into the core opening. - The core material is optically transparent. - Excess core material is removed from the substrate's surface.
Original Abstract Submitted
A method of making a semiconductor device includes defining an opening extending from a first side of a substrate to a second side of the substrate, wherein the first side of the substrate is opposite the second side of the substrate. The method further includes depositing a dielectric material into the opening, wherein the dielectric material has a first refractive index. The method further includes etching the dielectric material to define a core opening extending from the first side of the substrate to the second side of the substrate. The method further includes depositing a core material into the core opening, wherein the core material has a second refractive index different from the first refractive index, and the core material is optically transparent. The method further includes removing excess core material from a surface of the substrate.
