Student Designs Ionic Knife To Etch Transistors
Very interesting read here

"Using photoresist to create transistors can be a 20- to 100-step process," Ryna Karnik explained. "Using a focused beam of heavy gallium ions to etch the transistors directly takes six to seven steps." The student researcher has applied for a patent on the system.

"If Ryna's fabrication technique proves easily reproducible, reliable and scalable, it will be a valuable tool for chip designers by allowing them more flexibility when trying to debug a prototype chip,"
