Abstract: A plug connector for a cable having at least two signal conductors, in particular a star quad cable, having a signal conductor part and an insulating part which holds the signal conductor part. The signal conductor part has a spring lug, electrically and mechanically connected to a signal conductor, wherein the insulating part has an axial hole and a spring lug passes through each of said axial holes, wherein the holes are arranged to hold the spring lugs at a physical distance from one another.

Abstract: A manufacturing method for an integrated circuit memory includes providing a semiconductor substrate and depositing a charge-trapping dielectric layer. First and second bitlines are implanted and a wordline layer is deposited. A hard mask layer is deposited over the wordline layer. A photoresist is deposited over the wordline layer and used to form a hard mask. The photoresist is removed. The wordline layer is processed using the hard mask to form a wordline and the hard mask is removed. A reduced hydrogen, ultra-violet block data retention liner covers the wordline and the charge-trapping dielectric layer. The reduced hydrogen levels reduce the charge loss compared to prior art. The surface of the liner is processed to block UV light before completing the integrated circuit.

Abstract: A masking material (14) is formed on a foundation layer (12) and a substrate (10). A mask (16) is disposed onto the masking material (14) where a trench (26) is desired to be formed. An etch step removes all of the masking material (14) except at regions where the mask (16) was formed leaving a protruding portion (18) with an opening (20) on either side. An epi layer (24), is grown on the foundation layer (12) adjacent to the protruding portion (18) in the opening (20). A wet oxide etch process is used to remove the protruding portion (18) leaving a trench (26) formed in the epi layer (24). To complete the process, a silicon wet etch process is used to round off the corners at an edge (28) of the trench (26).

Abstract: A connector includes a first housing half and a second housing half, with one of the connector halves being a socket half, and the other connector half being a plug half. A latching mechanism is provided so that when the connector halves are assembled, they are latched together in the assembled position.

Following latching of the connector halves into the assembled condition, the CPA device may be slid forward to a final position to lock the latching mechanism to prevent the connector from being inadvertently unlatched. Also, if the connector halves are not fully and properly assembled, it is not possible to slide the CPA device into the final position.
