ABSTRACT:
In ion-implanted bubble memories where a patterned ion-implanted layer defines the propagation paths and the special functional elements, a uniform additional ion implant layer provides for a high degree of control over the nucleation level in the bubble material. Design flexibility and high generator margins are achieved.
