Microwave-Compatible Superconducting Films  

Neocera, Inc. 

Beltsville, MD 
 

A process for growing high transition temperature superconducting films of yttrium-barium-copper-oxide on sapphire or lanthanum aluminate substrate

• Developed innovative pulsed laser deposition hardware
• Products developed in the process include manual multilayer  deposition systems, target carrousel flange assembly, substrate heater flange assembly, and programmable substrate heater controller 

• Initial sales include $55K for pulsed laser deposition  hardware and $750K for high temperature superconducting  film and equipment
• Sales of all the various products developed increased to approxima- tely $3 M
• Staff was increased from 3 to 15 people

• For microwave engineering, procedure will reduce phase noise in planar microwave components such as local oscillators
• Size, weight, and microwave loss will be reduced when properly used in monolithic microwave integrated circuits
• The equipment developed can be used for material research at all temperatures
• High temperature superconducting films have been used as circuit switches using pulsed lasers to increase film temperature above critical temperature
