Abstract

PURPOSE:To prevent the increase in coercivity of a permalloy pattern by subjecting a resin layer to heat treatment in the magnetic bubble memory element wherein the pattern is formed on polyladder organosiloxane resin. CONSTITUTION:A thin magnetic film 12 is prepared on a non-magnetic substrate 11 by the liquid-phase growing method. An SiO2 film 13 is made by spattering, Mo, Au and Mo are evaporated, and thus a pattern 14 in three layers is prepared. The pattern is covered with a polyladder organosiloxane resin layer 15 and subjected to heat treatment at the temperature of 400-750 deg.C in air, whereby the pattern 16 of permalloy (main consitituent: Ni 80%, Fe 20%) is formed. Then, the polyladder organosiloxane resin is applied by spin coat and subjected to thermosetting, whereby a protection film 17 is formed. By this constitution, the coercivity is lowered and thereby the elctric power for driving the bubble can be reduced.
