A multitasking laser processing machine of excimer/femtosecond laser has been newly introduced in FUTA-Q. The excimer laser system can perform multiple micro fabrications simultaneously with the laser beam going through a mask. In this machine, the excimer and femtosecond laser processing can be overlapped consecutively on the same workpiece.
