Dotted seeds are implanted in a regular pattern upon an undersubstrate. A GaN crystal is grown on the seed implanted undersubstrate by a facet growth method. The facet growth makes facet pits above the seeds. The facets assemble dislocations from neighboring regions, accumulate the dislocations into pit bottoms, and make closed defect accumulating regions (H) on the seeds. The polycrystalline or slanting orientation single crystal closed defect accumulating regions (H) induce microcracks due to thermal expansion anisotropy. The best one is orientation-inversion single crystal closed defect accumulating regions (H). At an early stage, orientation-inverse protrusions are induced on tall facets and unified with each other above the seeds. Orientation-inverse crystals growing on the unified protrusions become the orientation-inverse single crystal closed defect accumulating regions (H).

A cache device is provided for use in a data processing apparatus to store data values for access by an associated master device. Each data value has an associated memory location in a memory device, and the memory device is arranged as a plurality of blocks of memory locations, with each block having to be activated before any data value stored in that block can be accessed. The cache device comprises regular access detection circuitry for detecting occurrence of a sequence of accesses to data values whose associated memory locations follow a regular pattern. Upon detection of such an occurrence of a sequence of accesses by the regular access detection circuitry, an allocation policy employed by the cache to determine a selected cache line into which to store a data value is altered with the aim of increasing a likelihood that when an evicted data value output by the cache is subsequently written to the memory device, the associated memory location resides within an already activated block of memory locations. Hence, by detecting regular access patterns, and altering the allocation policy on detection of such patterns, this enables a reuse of already activated blocks within the memory device, thereby significantly improving memory utilisation, thereby giving rise to both performance improvements and power consumption reductions.

A process for forming an etch mask having a discontinuous regular pattern utilizes beads, each of which has a substantially unetchable core covered by a removable spacer coating. Beads which have a core and a spacer coating are dispensed as a hexagonally-packed monolayer onto a thermo-adhesive layer, which is on a target layer. The beads are kept in place by a bead confinement wall. Following a vibrational step which facilitates hexagonal packing of the beads, the resultant assembly is heated so that the beads adhere to the adhesive layer. Excess beads are then discarded. Spacer shell material is then removed from each of the beads, leaving core etch masks. The core-masked target layer is then plasma etched to form a column of target material directly beneath each core. The cores and any spacer material underneath the cores are removed. The resulting circular island of target material may be used as an etch mask during wet isotropic etching of an underlying layer. Such a combination of plasma etching using the bead cores as a primary mask and a wet etch using the islands formed by the plasma etch as a secondary mask may be used to form micropoint cathode emitter tips in an underlying conductive or semiconductive layer.

In an exemplary embodiment, a contact lens of the present invention is capable of independently altering the refractive state of the eye in relation to fovea and peripheral retina so as to simultaneously correcting visual acuity while minimizing the signal for axial growth and hence myopic progression.
