Abstract: A high voltage transistor structure including a substrate, a first isolation structure, a second isolation structure, a gate structure, a first source and drain region, and a second source and drain region is provided. The first isolation structure and the second isolation structure are disposed in the substrate. The gate structure is disposed on the substrate, at least a portion of the first isolation structure, and at least a portion of the second isolation structure. The first source and drain region and the second source and drain region are located in the substrate on two sides of the first isolation structure and the second isolation structure. The depth of the first isolation structure is greater than the depth of the second isolation structure.

Abstract: A semiconductor device includes a single diffusion break (SDB) structure dividing a fin-shaped structure into a first portion and a second portion, an isolation structure on the SDB structure, a first spacer adjacent to the isolation structure, a metal gate adjacent to the isolation structure, a shallow trench isolation (STI around the fin-shaped structure, and a second isolation structure on the STI. Preferably, a top surface of the first spacer is lower than a top surface of the isolation structure and a bottom surface of the first spacer is lower than a bottom surface of the metal gate.

Abstract: A sea wave generating device includes a floating base, a generating assembly, a driving assembly, and a guiding housing. The floating base includes a base body and a cover plate. The generating assembly is secured in the base body and includes a lower magnetic wheel and a power generator. The driving assembly includes an upper magnetic wheel and a blade wheel. The upper magnetic wheel and the lower magnetic wheel are attracted magnetically. The guiding housing is secured to the base body and rests on the cover plate. The guiding housing covers the blade wheel and the upper magnetic wheel. Thus, when the sea wave is introduced into the guiding housing, the seawater pushes the blade wheel which drives the upper magnetic wheel which drives the lower magnetic wheel which drives the power generator to generate an electric power.
