Magnetic bubble memory device |
摘要 |
A hybrid magnetic bubble memory device comprising soft magnetic material propagation tracks and ion-implanted propagation tracks. In the soft magnetic material propagation track region, a layer made of a heat-resistant polymer was provided as an interlaminar insulating layer between a conductor and a pattern of a soft magnetic material. An insulator film made of a heat-resistant polymer was provided on the pattern made of a soft magnetic material. A passivation film made of an inorganic material was provided on the ion-implanted propagation tracks and the insulator film made of a heat-resistant polymer.
