Abstract: A metal etching process. A glue/barrier layer, a metal layer and an anti-refeletion layer are formed on a substrate. A three-stage etching step is performed. A break through step of etching is performed to pattern the glue/barrier layer. A main etching step is performed on the metal layer with chlorine, boron trichloride, and trifluoro-methane as etching gases. The trifluoro-methane is advantageous to produce a polymer during etching, so that the profile of the metal layer appears atilt. An over-etching step is then performed to ensure an insulation between neighboring wiring lines.

Abstract: A method of laser processing or laser modification of materials. The combination of ultrafast laser pulses and high-repetition rate (>100 kHz) bursts (or continuous operation) defines a new and unexpected regime for material processing. The high repetition rate controls thermal and/or other relaxation processes evolving between each ultrafast laser pulse that ‘prepares’ the sample surface or bulk to alter the interaction with subsequent ultrafast laser pulses and thereby improve or optimize the process, or enable a new process, that are not available at lower repetition rate. The addition of this laser-controlled thermal component, and/or the general control of relaxation processes, overcomes several current limitations of ultrafast laser processing at lower repetition rates (<100 kHz), providing means to further harness the many attributes of ultrafast lasers for general material processing and material modification applications.
