Abstract: A semiconductor device includes a fin structure. A source/drain region is formed on the fin structure. A first gate structure is disposed over the fin structure. A source/drain contact is disposed over the source/drain region. The source/drain contact has a protruding segment that protrudes at least partially over the first gate structure. The source/drain contact electrically couples together the source/drain region and the first gate structure.

Abstract: A composition with exogenous mitochondria as active ingredients, and a use thereof and a cell repairing method therefor. The composition includes exogenous mitochondria and at least one pharmaceutically or cosmetically acceptable carrier. The composition may further include an adjuvant, and the adjuvant is selected from a group consisting of serum, plasma, complement and at least the above two ingredients. The exogenous mitochondria are obtained from cells by a centrifugal purification method.

Abstract: A digital spectrophotometer and a spectrologial method for determining spectrum wavelength of an unknown illuminant, and the digital spectrophotometer has a base, an operating assembly and a photographic assembly. The operating assembly is attached to the base and has an operating pedestal, a rotating frame and a spectrometer. The rotating frame is connected rotatably to the operating pedestal. The spectrometer is connected solidly to the rotating frame. The photographic assembly is connected to the operating assembly. The spectrologial method is calculated the diffraction angle ? i and the wavelength of the unknown illuminant by putting the parameters into the into the first and second functions.
