Title:
Charged particle beam masking for laser ablation detailed machining
Document Type and Number:
Japanese Patent JP6129237
Kind Code:
B2
Abstract:
Improved method of and system for substrate micromachining is described. Preferred embodiments of the present invention provide improved methods for the utilization of charged particle beam masking and laser ablation. A combination of the advantages of charged particle beam mask fabrication and ultra short pulse laser ablation are used to significantly reduce substrate processing time and improve lateral resolution and aspect ratio of features machined by laser ablation to preferably smaller than the diffraction limit of the machining laser.
