Abstract: A semiconductor die package includes an inductor-capacitor (LC) semiconductor die that is directly bonded with a logic semiconductor die. The LC semiconductor die includes inductors and capacitors that are integrated into a single die. The inductors and capacitors of the LC semiconductor die may be electrically connected with transistors and other logic components on the logic semiconductor die to form a voltage regulator circuit of the semiconductor die package. The integration of passive components (e.g., the inductors and capacitors) of the voltage regulator circuit into a single semiconductor die reduces signal propagation distances in the voltage regulator circuit, which may increase the operating efficiency of the voltage regulator circuit, may reduce the formfactor for the semiconductor die package, may reduce parasitic capacitance and/or may reduce parasitic inductance in the voltage regulator circuit (thereby improving the performance of the voltage regulator circuit), among other examples.

The method further includes etching the unmasked portion of the coating and the metal over the first transistor structure using a dry etching process with a process pressure of from 30 to 60 (mTorr).

Abstract: A contact lens comprises an optical zone and a peripheral zone. The optical zone is used for vision correction. The peripheral zone surrounds the optical zone. The optical zone and the peripheral zone jointly define a geometric center and a horizontal axis passing through the geometric center. Two stabilization zones symmetrically arranged relative to the geometric center are formed in the peripheral zone. These stabilization zones gradually thicken relative to a base curved surface of the peripheral zone.

The gate stack includes a high-k dielectric layer, a work-function layer overlapping a bottom portion of the high-k dielectric layer, and a blocking layer overlapping a second bottom portion of the work-function layer. A low-resistance metal layer overlaps and contacts the work-function layer and the blocking layer. The low-resistance metal layer has a resistivity value lower than second resistivity values of both of the work-function layer and the blocking layer. A gate spacer contacts a sidewall of the gate stack.

Abstract: A pneumatic stapler has a main body internally loaded with straight staple-forming wires and including a staple-driving and a wire-bending control chamber. A staple-driving element carrier is movably mounted in the staple-driving control chamber and divides the latter into a first and a second staple-driving gas flowing space. When the staple-driving element carrier moves in the second staple-driving gas flowing space to push one staple out of the main body into a workpiece, the initially isolated first staple-driving control chamber is now communicable with the wire-bending control chamber, allowing part of the gas supplied to the pneumatic stapler to flow into the wire-bending control chamber and move a wire-bending element mounted therein to bend one staple-forming wire into a staple. Therefore, the pneumatic stapler requires only one pressure source to complete both staple-driving and wire-bending operations and can have more staple-forming wires loaded therein to provide high convenience in use.

Abstract: A roll staple manufacturing process enabling production of a high yield of staples at an effectively reduced manufacturing cost including the steps of providing a wire strip consisting of multiple wires arranged side-by-side; holding the wire strip in place with a holding unit; cutting the wire strip with a staple forming module to provide multiple staple banks; using a push module to push the staple banks from the holding unit to a guide rail set; applying an adhesive element to the staple banks while the same are continuously moved forward by the guide rail set; using a counting element to count the wires of the staple banks passing therethrough, and cutting the staple banks with a cutting element when the number of the wires passed through the counting element reaches a preset value, so as to provide a staple strip; and winding the staple strip on a winding element to form a roll staple.

Abstract: A hand-operated coil stapler includes a main body having a linkage system provided therein; a staple driving mechanism assembled to a front end of the main body and including a complex staple driver; a pusher and magazine assembly connected to a bottom of the main body and including a push rod having a staple-pushing spring fitted therearound; and a coil staple unit formed of bar-shaped staples. When the main body is downward pushed, the linkage system brings the complex staple driver to bend and drive a first staple of the coil staple unit into a workpiece. Meanwhile, the complex staple driver comes into contact with the push rod and forces the latter backward to compress the staple-pushing spring. When the main body is released, the staple-pushing spring elastically moves the push rod forward, bringing a subsequent staple to a position below the complex staple driver for a next stapling operation.
