Abstract: A semiconductor structure includes a source/drain feature in the semiconductor layer. The semiconductor structure includes a dielectric layer over the source/drain feature. The semiconductor structure includes a silicide layer over the source/drain feature. The semiconductor structure includes a barrier layer over the silicide layer. The semiconductor structure includes a seed layer over the barrier layer. The semiconductor structure includes a metal layer between a sidewall of the seed layer and a sidewall of the dielectric layer, a sidewall of each of the silicide layer, the barrier layer, and the metal layer directly contacting the sidewall of the dielectric layer. The semiconductor structure includes a source/drain contact over the seed layer.

Abstract: A toy block with slot tracks formed thereon takes the form of a hexahedron with six track surfaces. A slot is formed on each of at least one of the track surfaces and has multiple connection ends extending and connecting to different edges of the track surface. Each toy block can at most include six different slots to attain high degree of diversity and variety for playing the toy block. When multiple ones of the toy blocks are assembled, users just need to get the multiple toy blocks to approach each other and the multiple toy blocks can be quickly assembled into a toy block set with high degree of variation and entertaining effect.

Abstract: A display screen mounting structure includes a mounting frame unit comprising a base member for mounting on an upright support, a forked support arm extended from the base member, a connection rod member vertically pivotally mounted in the front end of the forked support arm and a connection plate affixed to the outer end of the connection rod member, and a support frame unit comprising a channel frame fastenable to the connection plate and two cushion members respectively capped on the shoulder plates for stopped against the display screen.
