Synopsis

The focus of this work was the growth, characterization of ultra-thick film C-axis oriented Barium Hexaferrite films. Polycrystalline ferrite structures have been engineered using the Pulsed Laser Deposition (PLD) and Modified Liquid Phase Epitaxy (MLPE) reflow techniques. It was demonstrated that the Plasma Enhanced Chemical Vapor Deposition (PECVD) produces films with poor quality and magnetic properties. In this work we are introducing a novel Modified Injection Molding (MIM) technique for fabrication of ultra-thick M- type Barium Ferrite films that can be utilized in monolithic microwave integrated circuits (MMIC) devices with operating range from 1 to 100GHZ. This is an extremely low cost fabrication process, with very high rate of repeatability and success.
