Abstract: A semiconductor process system includes a process chamber. The process chamber includes a wafer support configured to support a wafer. The system includes a bell jar configured to be positioned over the wafer during a semiconductor process. The interior surface of the bell jar is coated with a rough coating. The rough coating can include zirconium.

Abstract: Provided are semiconductor devices that include a first gate structure having a first end cap portion, a second gate structure having a second end cap portion coaxial with the first gate structure, a first dielectric region separating the first end cap portion and the second end cap portion, a first conductive element extending over the first gate structure, a second conductive element extending over the second gate structure, and a gate via electrically connecting the second gate structure and the second conductive element, with the first dielectric region having a first width and being positioned at least partially under the first conductive element and defines a spacing between the gate via and an end of the second end cap portion that exceeds a predetermined distance.

Abstract: A shoe accessory of a shoe adaptive for activating a bottom of a foot wearing the shoe is provided. The bottom of the foot has a forefoot, a heel, and an arch between the forefoot and the heel. The shoe accessory includes a main body and a plurality of stimulating elements mounted to the main body. Each of the stimulating elements is movable universally on the main body and is adapted to exert a pressing force on a non-fixed point of the bottom of the foot to stimulate the arch.

Abstract: A clamping piece structure includes a one-piece clamping piece body (10). The body (10) includes a first folding piece portion (11), a second folding piece portion (12), a third folding piece portion (13), and a connecting piece portion (14). A first bending portion (15) is provided at a central section of an edge of the first folding piece portion (11) for interconnection with the connecting piece portion (14). A second bending portion (16) is provided at the other edge of the first folding piece portion (11) for interconnection with the second folding piece portion (12). A third bending portion (17) is provided at an edge of the second folding piece portion (12) for interconnection with the third folding piece portion (13). An engagement section (141) is provided at an outer edge of the connecting piece portion (14). An opening (121) is formed in a central section of the second folding piece portion (12). The connecting piece portion (14) is insertable through the opening (121).

Abstract: An improved turntable of a nylon fiber grinding wheel, which is integrally made of plastic by injection has a predetermined amount of flexibility. The turntable has a locking hole provided at a center portion therethrough, and a ring groove encircling the locking hole on a top surface of the turntable. The ring groove has a plurality of through slot arranged spacedly and radially and defines a plurality of ribs arranged radially and respectively between the through slots. A bottom surface recess of the turntable and ring groove are overfilled with a gluing agent such as epoxy resin, so that the gluing agent would also fill in the plurality of through slots and enwrap around the plurality of ribs. Therefore, a nylon fiber grinding plate can be attached to the bottom surface recess of the turntable by means of the gluing agent.
