    A concise survey is given on the technology and operational aspects of magnetic bubble devices. A proper functioning of such devices implies a special sequence of thin film layers of monocristalline garnet, permalloy, silica and conductor material, some only present in specific patterns. Attention is given to the necessity of simplifying the construction in order to get a sufficient degree of miniaturization. Novel approaches are outlined to overcome the problems related herewith.Nous prĂ©sentons un rĂ©sumĂ© sur la technologie et les mĂ©thodes de fonctionnement des dispositifs Ă  bulles magnĂ©tiques. Un fonctionnement adĂ©quat de ces dispositifs exige une succession de dĂ©pĂŽts de couches minces de grenat monocristallin, de nickel-fer, de silice et de matĂ©riaux conducteurs, certains dĂ©pĂŽts Ă©tant effectuĂ©s selon des configurations spĂ©cifiques. Nous soulignons la nĂ©cessitĂ© de simplifier la construction pour obtenir un degrĂ© suffisant de miniaturisation. Nous dĂ©crivons les dĂ©marches qui peuvent ĂȘtre entreprises Ă  cette fin
