    摘要： A template having tapered openings can be employed to enable injection of underfill material through gaps having a width less than a lateral dimension of an injector needle for the underfill material. Each tapered opening has a first lateral dimension on an upper side and a second lateral dimension on a lower side. Compliant material portions can be employed to accommodate variations in distance between the template and stacked semiconductor chips and/or an injector head. Optionally, another head can be employed to apply compressed gas to push out the underfill material after the underfill material is applied to the gaps. Multiple injector heads can be employed to simultaneously inject the underfill material at different sites. An adhesive layer can be substituted for the at least one lower compliant material portion.

    摘要： A magnetic device according to one embodiment includes a source of flux; a magnetic pole coupled to the source of flux, the magnetic pole having two or more gaps; and a low reluctance path positioned towards at least one of the gaps and not positioned towards at least one other of the gaps for affecting a magnetic field formed at the at least one of the gaps when the source of flux is generating flux. Other disclosed embodiments include devices having coil turns with a non-uniform placement in the magnetic yoke for altering a magnetic field formed at the at least one of the gaps during writing. In further embodiments, a geometry of the magnetic pole near or at one of the gaps is different than a geometry of the magnetic pole near or at another of the gaps to help equalize fields formed at the gaps when the source of flux is generating flux.

    摘要： Self-servo-writing of multi-slot timing patterns is described. Individual timing marks are replaced with groups of timing mark slots. At each timing mark location, a time measurement is made by detecting a timing mark in one of the slots. Also, extensions to the existing timing marks are written in other slots. The combination of timing measurements at every timing mark and extensions to those timing marks written at every opportunity improves the overall precision of the timing propagation. The improved accuracy of timing mark placement produces a commensurate improvement in the placement of the concomitantly written servo-data. In addition, the alignment accuracy of the written pattern is less sensitive to variations in rotation speed and variations in the shape of written transitions. Moreover, only a single disk revolution is required at each servo radius to write servo data and propagate the timing marks to maintain timing alignment.
