ABSTRACT:
A gap between sets of contiguous discs defined by unimplanted regions in an otherwise ion-implanted bubble layer allows a merge function to be achieved. The alignment of the gap axis with an axis of symmetry of the bubble layer and the width of the gap are important considerations in the performance of the merge.
