Rapid Batch Manufacturing of True 3-D Micro-Devices

What is EFAB?

EFAB is a a new technology for the rapid production of micro-devices previously impossible to make.

EFAB is being commercialized by MEMGen Corporation of Burbank, California. Please see www.MEMGen.com for the latest information.

EFAB makes possible for the first time
batch fabrication of extremely complex, arbitrary 3-D micro-devices having features far smaller than a human hair. EFAB can produce an unlimited variety of micromachines, including complex microelectromechanical systems (MEMS) on a chip that combine tiny mechanisms with microelectronics.

EFAB promises to enable totally new micro-miniaturized products (e.g., instruments for minimally-invasive surgery).

EFAB was initially invented at the
USC/Information Sciences Institute (ISI) and developed at ISI and the University of Southern California Dept. of Materials Science & Engineering with funding from the Defense Advanced Research Projects Agency (DARPA).
