Abstract
Official abstract text for this publication.
Embodiments relate to buried structures for silicon devices which can alter light paths and thereby form light traps. Embodiments of the lights traps can couple more light to a photosensitive surface of the device, rather than reflecting the light or absorbing it more deeply within the device, which can increase efficiency, improve device timing and provide other advantages appreciated by those skilled in the art.
First claim
Opening claim text (preview).
The invention claimed is: 1. A device comprising: a silicon structure having an exposed surface be exposed to light rays; a photoelectrically active portion located beneath the exposed surface within the silicon structure; and an internal structure located beneath the active portion, the internal structure having art interface surface generally parallel to the exposed surface at which total internal reflection of light rays occurs such that at least some of the light rays are…
