Abstract: Embodiments disclosed herein include semiconductor devices and methods of forming such devices. In an embodiment a semiconductor device comprises a first interlayer dielectric (ILD), a plurality of source/drain (S/D) contacts in the first ILD, a plurality of gate contacts in the first ILD, wherein the gate contacts and the S/D contacts are arranged in an alternating pattern, and wherein top surfaces of the gate contacts are below top surfaces of the S/D contacts so that a channel defined by sidewall surfaces of the first ILD is positioned over each of the gate contacts, mask layer partially filling a first channel over a first gate contact, and a fill metal filling a second channel over a second gate contact that is adjacent to the first gate contact.

Abstract: A method for generating amplicon constructs of a target sequence is disclosed, the method comprising providing a target sequence; an oligonucleotide probe, comprising a universal sequence and further comprising, at or towards its 5? end, a target specific sequence capable of hybridising to the reverse complement of a sequence at, or flanking one of the 3? ends of the target sequence; a universal primer, comprising at its 3? end a sequence capable of hybridising to the universal sequence of the oligonucleotide probe and performing a Polymerase Chain Reaction (PCR).

Abstract: A method of lining a wellbore having a tubular string cemented therein includes: running a liner string into the wellbore using a workstring having a liner deployment assembly (LDA) latched to the liner string; hanging the liner string from the tubular string and setting a seal of the liner string against the tubular string; opening a crossover valve of the liner string located below the set seal; and pumping cement slurry through the open crossover valve and down an annulus formed between the liner string and the wellbore.

Abstract: A method and apparatus for conducting a reverse flow operation. The apparatus may be lowered into a wellbore on a work string, and includes an opening device, a closing device, and a locking device disposed in a housing. Pressurized fluid supplied through the work string may actuate the opening device to open fluid flow through ports in the housing. Pressurized fluid from the annulus may be supplied through the port in the reverse flow direction to actuate the locking device to enable fluid flow up through the work string back to the surface, and to release the closing device. Pressurized fluid supplied through the work string may actuate the closing device to close fluid flow through the ports in the housing.

Abstract: A method and apparatus for locking the drive hubs of a forms overlay station in a laser electrographic printer to its transparent forms overlay drum includes counterboring a plurality of holes through the drum into the hubs, inserting a resilient member such as an O-ring into each counterbored hole, and compressing the resilient member to form an interference fit among the compressed resilient member and an interface formed within the counterbored hole by the drum and hubs.

Abstract: This invention relates to a system for positioning a high-speed endless loop printing band of the type used on impact band printers. The band positioning apparatus includes a first sensor for being placed adjacent the edge of the endless loop band for detecting the drift of the edge to one side of a reference line. A second sensor is provided adjacent an area of the endless loop printing band for detecting the drift of the edge to the other side of the reference line. A microprocessor is coupled to the first and second sensors for generating a correcting output signal to a step motor. The step motor is coupled to a pulley in guiding communication with the endless loop printing band for displacing the pulley toward the reference line, thereby correcting the undesired movement of the edge of the endless loop printing band.
