Abstract: A method for forming a semiconductor structure is provided. The method includes forming a spacer layer along a first fin structure and a second fin structure, etching a first portion of the spacer layer and the first fin structure to form first fin spacers and a first recess between the first fin spacers, etching a second portion of the spacer layer and the second fin structure to form second fin spacers and a second recess between the second fin spacers, and forming a first source/drain feature in the first recess and a second source/drain feature in the second recess. The second fin structure is wider than the first fin structure. The first fin spacers have a first height, and the second fin spacers have a second height that is greater than the first height.

Abstract: In some examples, a device can include a first antenna having a first wireless connection with a first computing device, a second antenna having a second wireless connection with a second computing device, and a controller to determine a signal strength of the first wireless connection and a signal strength of the second wireless connection, designate, in response to the signal strength of the first wireless connection being greater than a threshold signal strength, the first wireless connection as an active connection and the second wireless connection as a standby connection, and cause the peripheral device to communicate with the first computing device via the active connection of the first antenna while maintaining the second wireless connection to the second computing device via the second antenna, where the second wireless connection remains as the standby connection.

Abstract: A method includes receiving a device design layout and a scribe line design layout surrounding the device design layout. The device design layout and the scribe line design layout are rotated in different directions. An optical proximity correction (OPC) process is performed on the rotated device design layout and the rotated scribe line design layout. A reticle includes the device design layout and the scribe line design layout is formed after performing the OPC process.

Abstract: A three dimensional jigsaw puzzle has pieces with protrusions and cutouts. The protrusions and cutouts of every two adjacent pieces correspond to each other. Each piece is a tangential area of a sphere so that when the pieces are all combined, the sphere is formed.

Abstract: A peer-to-peer based secondary key search method and system for cluster databases is disclosed. A cluster database has a plurality of storage nodes and each storage node is assigned with a node number and stores a plurality of records. A search term input means couples to the plurality of storage nodes for retrieving a record at a storage node. The search term input means calculates a first node number based on a hash function of a secondary key, queries the first storage node with the secondary key for retrieving a corresponding primary key, calculates a second node number based on a hash function of the primary key, and then queries the second storage node with the primary key for retrieving a corresponding record.

Abstract: A cylindrical jigsaw puzzle includes a bottom rim having an outer flange, an inner flange and a first gap between the outer flange and the inner flange, a top rim having a ring body, a positioning flange extending from an inner face of the ring body and a second gap defined between the ring body and the positioning flange, top puzzle pieces each having a first assembly edge corresponding to and received in the second gap of the top rim and bottom puzzle pieces each having a second assembly edge corresponding to and received in the first gap of the bottom rim. Combination among the top puzzle pieces with the top rim mounted thereon, bottom puzzle pieces with the bottom rim mounted thereunder and a cap mounted on top of the top rim is able to accomplish a cylinder.

Abstract: A 3D jigsaw puzzle includes puzzle pieces each having multiple arms and cutouts structurally complementary to the arms of an adjacent puzzle piece. A surface engagement exists between a peripheral edge defining each of the arms of a puzzle piece and a peripheral edge defining each of the cutouts of the adjacent puzzle piece so that the two adjacent puzzle pieces are combined. A linear engagement exists between opposite sides defining each arm of the puzzle piece and opposite sides defining each cutout of the adjacent puzzle piece.

Combination among the top puzzle pieces with the top rim mounted thereon, bottom puzzle pieces with the bottom rim mounted thereunder and a cap mounted on top of the top rim is able to accomplish a cylinder.

Abstract: A cylindrical sliding block jigsaw puzzle includes a barrel as a support; multiple arcuate sliding blocks combined together to construct a pattern on an outer periphery of the barrel; and an unslidable block detachably attached to an empty area defined in the outer periphery of the barrel. Beside being playable as a sliding block jigsaw puzzle, the cylindrical sliding block jigsaw puzzle also can be used as a pen container or a money box.

Abstract: A cylindrical sliding block jigsaw puzzle includes a barrel as a support; multiple arcuate sliding blocks combined together to construct a pattern on an outer periphery of the barrel; and an immovable sliding block detachably attached to an empty area defined in the outer periphery of the barrel. Beside being playable as a sliding block jigsaw puzzle, the cylindrical sliding block jigsaw puzzle also can be used as a pen container or a money box.

Abstract: A jigsaw puzzle includes a base and multiple puzzle piece blocks detachably mounted on top of the base. The puzzle piece blocks are composed of corner puzzle piece blocks each having a first marking to show that the corner puzzle piece block is located at a corner of the base, side puzzle piece blocks each having a second marking to show that the side puzzle piece block is located at a side of the base and central puzzle piece blocks surrounded by the corner puzzle piece blocks and the side puzzle piece blocks.
