Abstract: A semiconductor structure is provided and includes a first gate structure, a second gate structure, and at least one local interconnect that extend continuously across a non-active region from a first active region to a second active region. The semiconductor structure further includes a first separation spacer disposed on the first gate structure and first vias on the first gate structure. The first vias are arranged on opposite sides of the first separation spacer are isolated from each other and apart from the first separation spacer by different distances.

Abstract: A lock cylinder includes a sliding fastening bolt, and an unlocking mechanism disposed in a housing. The characteristics thereof are that the unlocking mechanism is consisted of a fixed cylindrical block, a lock cylinder core and a pressing cylindrical block that are all provided with a plurality of corresponding orifices, respectively. A portion of the orifices at the fixed cylindrical block and the pressing pin cylindrical block is provided with spring pins and a pressing pin respectively. The lock cylinder core further impels the fastening bolt by an interlocking mechanism while a key is provided with an inserting pin for inserting into the orifice at the pressing cylindrical block to push the pressing pin inward that further pushes the spring pin into the orifice at the fixed cylindrical block, thus further turning the lock cylinder core and impelling the sliding fastening bolt for unlocking and obtaining an optimal anti-theft effect.
