Abstract: A semiconductor device structure is provided. The semiconductor device structure includes a first source/drain epitaxial feature formed over a substrate, a second source/drain epitaxial feature formed over the substrate, two or more semiconductor layers disposed between the first source/drain epitaxial feature and the second source/drain epitaxial feature, a gate electrode layer surrounding a portion of one of the two or more semiconductor layers, a first dielectric region disposed in the substrate and in contact with a first side of the first source/drain epitaxial feature, and a second dielectric region disposed in the substrate and in contact with a first side of the second source/drain epitaxial feature, the second dielectric region being separated from the first dielectric region by a substrate.

Abstract: A method of making a ROM structure includes the operations of forming an active area having a channel, a source region, and a drain region; depositing a gate electrode over the channel; depositing a conductive line over at least one of the source region and the drain region; adding dopants to the source region and the drain region of the active area; forming contacts to the gate electrode, the source region, and the drain; depositing a power rail, a bit line, and at least one word line of the integrated circuit against the contacts; and dividing the active area with a trench isolation structure to electrically isolate the gate electrode from the source region and the drain region.

Abstract: An insertion type fuse with breakage indication comprises a seat having a long receiving chamber for receiving a metal fuse; an rectangular bi-directional SMD form LED set being located on the buckle portions; the LED set being a coating device and being high temperature tolerant; the LED set being connected to a circuit; the LED including two LEDs and being serially connected with a voltage divided resistor; a fuse wire being connected between the LED set and a load; the LED set being buckled to the buckle portions; when the fuse wire breaks, light will emit out so as to show that the fuse wire breaks; thereby a break fuse can be fined rapidly. In assembly, the seat and the cover are integrally formed. The LED set is adhered to the metal fuse and then the metal fuse is assembled into the long receiving chamber.

Abstract: A tool box includes a casing with at least one open side for a plurality of boxes pivotally received therein. A link is pivotally connected to the boxes and located at a distance from the pivotal point of the boxes. An activation member is pivotally connected to one of the boxes and has a slot for receiving a boss extending from the link so that when pivoting the activation member, the link pivots the boxes to open. A spring is connected between the activation member and the casing so as to close all the boxes by pulling the activation member.

Abstract: A ratchet tool includes a toothed inner periphery defined in the ring-shaped head and a rotatable member is engaged with the toothed inner periphery. A recess is defined in a surface of the head and a driving member is rotatably received in the recess. A notch is defined in a side defining the recess and communicates between the recess and a central hole in the head. An elongated protrusion extends from the rotatable member and a disk is securely mounted to the protrusion. The driving member is rotatably engaged with the disk so that when rotating the driving member, the rotatable member is able to be rotated at a small angle.

Abstract: A ratchet wrench includes a ring-shaped head having a threaded inner periphery and an operation member is rotatably retained in the head. The operation member has a ridge member extending from one end thereof and two pawl members are respectively retained on two sides of the ridge member. Each pawl member has a first side with teeth defined therein and a second side of each pawl member includes two inclined surfaces on two end of the second side and a straight surface is connected between the two inclined surfaces. The teeth of each pawl member are engageable with the threaded inner periphery of the head. One of the two inclined surfaces and the straight surface of each pawl member is engaged with respective one of the two parallel surfaces of the ridge member. An operation disk is mounted to the head and two torsion springs are respectively connected between the two pawl members and the operation disk.

Abstract: A damaged screw removing screwdriver includes a handle and a shank extending from the handle. The shank has a distal end for being engaged with slots in the head of a bolt. A plurality of blade portions extend radially outward from the distal end of the shank and each blade portion has a cutting edge and a corner. The handle has a plate attached to the distal end thereof so that the blade portions cut into the material of the head of the bolt by impacting the plate on the handle. By the screwdriver, the bolt having rounded slots in the head can still be rotated.

Abstract: A ratchet tool includes a head and a shank extending from the head in which a ratchet and a pawl are received in the head. A rod is rotatably inserted in the the shank and a grip is connected to the distal end of the shank. The grip is detachably connected to the first end of the rod, and an actuating member is connected to the second end of the rod. The actuating member is engaged with the ratchet which is rotated by the actuating member by rotating the grip. Therefore, the ratchet together with a bit or a socket connected to the ratchet are rotated simply by rotating the grip.

Abstract: A retractable knife device includes a first and a second blade respectively and retractably received in two ends of a casing of the tool. A connecting device is connected between the two blades and has a knob slidably disposed to a side of the casing. The first blade is moved to extend from the casing by a trigger device and the second blade is moved to extending from the casing by moving a pin member connected thereto which slidably extends from the casing. A spring has one end thereof fixedly connected to the casing and the other end thereof connected to the first blade. The connecting device ensures that only one of the first blade and the second blade can be moved to extend from the casing when in use.
