摘要:
Apparatus for a photo-induced process are provided, which implement a transparent film (instead of an optical window), to reduce light absorption loss that would result from use of an optical window. A photo-induced process apparatus eliminates problems of conventional systems which use optical windows, such as blurring an optical window and the surface of a light source, photo absorption loss due to the optical window and/or a purge cleaning gas, and dust generation by a moving part such as a flexible curtain. A photo-induced process apparatus efficiently utilizes light emitted from a light source.

Methods of forming a semiconductor device may include forming a fin-type active pattern that extends in a first direction on a substrate, the fin-type active pattern including a lower pattern on the substrate and an upper pattern on the lower pattern. A field insulating layer is formed on the substrate, the sidewalls of the fin-type active pattern, and a portion upper pattern protruding further away from the substrate than a top surface of the field insulating layer. A dummy gate pattern that intersects the fin-type active pattern and that extends in a second direction that is different from the first direction is formed. The methods include forming dummy gate spacers on side walls of the dummy gate pattern, forming recesses in the fin-type active pattern on both sides of the dummy gate pattern and forming source and drain regions on both sides of the dummy gate pattern.

An apparatus and method is configured to detect the proximity of an object using a proximity sensor in a portable terminal. A method for detecting the proximity of an object in a portable terminal mounted with a proximity sensor includes setting a reference light-receiving quantity according to a hairstyle of a user of the portable terminal, emitting light, detecting a light-receiving quantity corresponding to the emitted light, and determining the proximity/non-proximity of an object by comparing the light-receiving quantity with the reference light-receiving quantity.

The manufacturing a semiconductor device includes providing a substrate supporting a gate electrode, amorphizing and doping the source/drain regions located on both sides of the gate electrode by performing a pre-amorphization implant (PAI) process and implanting C or N into the source/drain regions in or separately from the PAI process, forming a stress inducing layer on the substrate to cover the amorphized source/drain regions, and subsequently recrystallizing the source/drain regions by annealing the substrate. The stress inducing layer may then be removed. Also, the C or N may be implanted into the entirety of the source/drain regions after the regions have been amorphized, or only into upper portions of the amorphized source/drain regions.

摘要:
A photocathode structure having a photoelectric face plate protective layer, in order to prevent a photoelectric effect from being deteriorated sharply due to a high reaction of oxygen with respect to most of existing photoelectric face plate materials when the photoelectric face plate used for generating photoelectrons by a photoelectric effect is exposed to the atmosphere, is provided. For example, a diamond-like carbon thin layer is used as a photocathode protective layer, to thereby perform a function of protection of the photoelectric face plate through isolation of the photoelectric face plate from the atmosphere and enable electrons generated from the photoelectric face plate to pass through a diamond-like carbon thin layer, which is deposited thinly, by the tunneling effect so that the performance of the photocathode is not affected. By using the protective layer, the processes subsequent to the photoelectric face plate deposition process can be freely performed in the atmosphere, to thereby simplify the whole process. As a result, a production cost is lowered, and manufacturing of a device or apparatus using a large-are photocathode is facilitated.
