Abstract: A display device includes an imaging element, a flat surface light source and a polarization beam splitter. The flat surface light source is used for providing plural illumination beams. A normal line of the flat surface light source and a normal line of the imaging element are not perpendicular to each other. The polarization beam splitter is arranged between the flat surface light source and the imaging element, and has a geometric surface. When the illumination beams from the flat surface light source are projected on the geometric surface, the illumination beams are reflected to the imaging element. The imaging beams from the imaging element are transmitted through the geometric surface. Consequently, an image is outputted. An imaging surface of the imaging surface can be irradiated uniformly by the illumination beams on within a specified viewing angle.

Abstract: A head-mounted display and an optical device are provided. The head-mounted display includes a display element, the optical device and an optical lens. Along an optical axis of the head-mounted display, the optical device includes a polarization beam splitter, a first phase retarder, a beam splitting element and a second phase retarder sequentially. The optical device receives plural light beams from the display element. The optical device is capable of travelling the light beams back and forth many times. The distance between the display element of the head-mounted display and the human eyes is shortened. Consequently, thus the volume of the head-mounted display is reduced.

Abstract: A method for preparing a chondroitin sulfate-polycaprolactone copolymer includes subjecting a chondroitin sulfate component and a polycaprolactone polymer to an atom transfer radical polymerization reaction in the presence of a catalyst.

Abstract: A method of focus and a focusing apparatus and a detecting module are provided. The detecting module includes an ellipse curved-surface reflection device and a light detector. The ellipse curved-surface reflection device has a beam gate, a first focus and a second focus. A light beam is focused by a light focusing device, and is projected on a surface of an object to be detected through the beam gate. The ellipse curved-surface reflection device reflects the light beams reflected or scattered by the object. The light detector is disposed on the second focus for receiving the light beam reflected by the ellipse curved-surface reflection device to generate a detecting result, by which a distance between the light focusing device and the surface of the object to be detected is adjusted, so that the light beam is correctly focused on the surface of the object.

Abstract: A method for manufacturing semiconductor shallow trench isolation is performed as follows. First, a semiconductor substrate including at least one shallow trench is provided, and the shallow trench is filled with Spin-On-Dielectric (SOD) material, e.g., polysilazane, to form a SOD material layer. Then, the SOD material layer is subjected to a planarization process. Oxygen ions are implanted into the SOD material layer to a predetermined depth, and a high temperature process is performed afterwards to transform the portion of the SOD material layer having oxygen ions into a silicon oxide layer. The oxygen ions can be implanted by plasma doping, immersion doping or ion implantation.
