Abstract: Methods of cutting gate structures and fins, and structures formed thereby, are described. In an embodiment, a substrate includes first and second fins and an isolation region. The first and second fins extend longitudinally parallel, with the isolation region disposed therebetween. A gate structure includes a conformal gate dielectric over the first fin and a gate electrode over the conformal gate dielectric. A first insulating fill structure abuts the gate structure and extends vertically from a level of an upper surface of the gate structure to at least a surface of the isolation region. No portion of the conformal gate dielectric extends vertically between the first insulating fill structure and the gate electrode. A second insulating fill structure abuts the first insulating fill structure and an end sidewall of the second fin. The first insulating fill structure is disposed laterally between the gate structure and the second insulating fill structure.

Abstract: According to an exemplary embodiment, a method of forming a vertical device is provided. The method includes: providing a protrusion over a substrate; forming an etch stop layer over the protrusion; laterally etching a sidewall of the etch stop layer; forming an insulating layer over the etch stop layer; forming a film layer over the insulating layer and the etch stop layer; performing chemical mechanical polishing on the film layer and exposing the etch stop layer; etching a portion of the etch stop layer to expose a top surface of the protrusion; forming an oxide layer over the protrusion and the film layer; and performing chemical mechanical polishing on the oxide layer and exposing the film layer.

Abstract: A wrench includes a wrench body, a ratchet wheel, a locking member and a connecting implement. The ratchet wheel is rotatably mounted on the wrench body and provided with two slots. The connecting implement is mounted on the ratchet wheel and provided with a retaining groove. The locking member is movably mounted on the ratchet wheel and has two locking portions mounted in the two slots of the ratchet wheel and locked in the retaining groove of the connecting implement. In such a manner, the wrench only needs to provide a single locking member, thereby decreasing the cost of fabrication.

Abstract: A ratchet wrench includes a head with a first room in which a ratchet wheel is rotatably received. A second room is defined in the inner periphery of the first room and a pawl is received in the second room. The pawl is biased by a resilient member in a recess defined in the inner periphery of the second room. A restriction member is located in the second room and has a first contact portion for contacting one end of the pawl, a second contact portion for contacting the engaging teeth of the pawl, and a contact corner for contacting the inside of the second recess. A gap between the first contact portion and the end of the pawl is 0 to 1 mm. The restriction member restricts the movement of the pawl in the second room.

Abstract: A ratchet wretch includes a first recess, a second recess and a third recess. A ratchet wheel is rotatably located in the first recess and a pawl is located in the second recess. The pawl has a curved recess defined in the rear side thereof and a protrusion extending therefrom. A first face is defined between the protrusion and the curved recess. A second face is defined in the pawl and located away from the third recess. The rotatable unit comprises a rotatable member, a first hat and a resilient member. The rotatable unit has a circular rod pivotably connected to the third recess. The circular rod has a restriction slot and three top surfaces. One of the top surfaces contacts the second face to restrict the rotatable member from disengaging from the third recess. The first hat and the resilient member are located in the restriction slot.

Abstract: The present invention discloses a ratchetable open-ended wrench comprising wrench body and retractable jaw member. The wrench body comprises head with two opposite jaws and a receiving hole. The inner surface of the receiving hole has a sunken slot with an inner circular arc surface. The retractable jaw member is slidably mounted in the sunken slot and has two opposite sides, and one side is directing to the receiving hole and has a second engaging portion. The retractable jaw member and the head are against with an elastic member. The retractable jaw member is able to move from a first position to a second position in the sunken slot, and is able to limit a workpiece to rotate in the receiving hole when at the first position and to allow the workpiece to rotate in the receiving hole when at the second position.
