A functional optical device is disclosed. The optical functional device integrates a coupling unit, a light-receiving element and an optical waveguide on a semiconductor substrate. The coupling unit extracts an optical signal by interfering between signal light and local light. The optical waveguide carries the optical signal from the coupling unit to the light-receiving element. The light-receiving element receives the optical signal. The semiconductor substrate provides a heavily doped conducting layer and a buffer layer that is un-doped or lightly doped with impurities by density smaller than density of impurities in the conducting layer. The conducting layer and the buffer layer continuously and evenly expand from the optical waveguide to the light-receiving element. |

A method of manufacturing a liquid crystal display includes: forming a sacrificial layer by stacking a non-photosensitive resin; initiating formation of an etch stop layer on the sacrificial layer; forming a photoresist pattern; completing the etch stop layer using the photoresist pattern; ashing the photoresist pattern and the sacrificial layer by using the completed etch stop layer as a mask; forming a microcavity by removing the sacrificial layer; and forming a liquid crystal layer in the microcavity. The horizontal area occupied by the sacrificial layer is reduced by forming the common electrode or the etch stop layer at an upper side, thereby increasing the aperture ratio. Further, the vertical electric field is generated without distortion by horizontally forming the common electrode on the sacrificial layer and forming no common electrode on the sidewall thereof. |

“Hybrid photonic devices” describe devices wherein the optical portion—i.e., the optical mode, comprises both the silicon and III-V semiconductor regions, and thus the refractive index of the semiconductor materials and the refractive index of the bonding layer region directly effects the optical function of the device. Prior art devices utilize an optically compliant layer that is the same material as the III-V substrate; however, during the final sub-process of the bonding process, the substrates must be removed by acids. These acids can etch into the bonding layer, causing imperfections to propagate at the interface of the bonded material, adversely affecting the optical mode shape and propagation loss of the device.Embodiments of the invention utilize a semiconductor etch-selective bonding layer that is not affected by the final stages of the bonding process (e.g., substrate removal), and thus protects the bonding interface layer from being affected. |
