Title: Composite type magnetic bubble memory element
Inventor: IKEDA HITOSHI
IPC: G11C11/14
Filed: 1983-06-01
Abstract: PURPOSE:To expand remarkably the overall operation margin of a bubble memo ry composed of composite type magnetic bubble memory elements, by commonly using a bias magnetic field range in which a bubble can exist as much as possible at each transferring path section using different bubble transferring systems of the composite type magnetic bubble memory elements. CONSTITUTION:Since it is necessary to perform ion implantation below a ''Permalloy'' transferring path only, an area at which an ion implantation transferring path is to be formed is masked with an AZ resist 4. The ion implantation into the boundary between the ''Permalloy'' transferring path 11 and the ion implantation transferring path is performed after the AZ resist 4 is tapered. When this method is used, a bubble can be transferring across the boundary of the transferring paths. Thereafter, patterns of the ion implantation transferring path, ''Permalloy '' transferring path, bubble generator, detector, etc., are performed by using conventional element manufacturing processes, and thus, a composite type bubble memory element is manufactured. The transfer characteristics of the composite element of 12%, whereas a margin loss of a little more than this invention shows an excellent overall common margin of a little more than 12%, whereas a margin loss of a little more than 5% is found due to the difference between bias magnetic field ranges of conventional both transferring paths.
