A New Phase Shifting Technique for Deep UV Excimer Laser Based Lithography
This paper reports simulation and experimental details of a novel phase shifting technique based on laser interferomeiry. Phase shifting is one of the most promising techniques L 2 for the fabrication ofhigh density DRAM's. In recent years many kinds of phase shifting methods have been proposed to extend the resolution limit and contrast of image patterns . These techniques however, have severa...
متن کاملContact and proximity lithography using 193nm Excimer Laser in Mask Aligner
In this paper we describe the use of an Excimer laser for full-field lithography in a Mask Aligner. The DUV light from the Excimer laser is homogenized by using micro lens based optical integrators instead of a macro lens-array. A simulation of the intensity distribution for 5 μm squares was performed to visualize the diffraction effects and to show the potential of 193 nm illumination. It is d...
متن کاملThe Excimer Laser
By Maria Clara Arbelaez, MD; and Thomas Magnago, Dipl-Ing Due to recent advances in refractive surgery, the complexities of correcting irregular astigmatism can now receive closer attention than ever before. Today, subjective evaluation of the patient’s refractive deficit may not produce an accurate depiction of his preexisting astigmatism. To minimize poor postoperative results, the golden rul...
متن کاملExcimer laser trabeculotomy.
ous fluid by producing 0.5-mm holes. There is no reference given to this observation, therefore it is not clear how this observation was determined. The article states that the laser fiber is 200 m. It is unclear how this would create 500m ostia. On page 286, an aiming beam is mentioned in the Surgical Technique section. However, unless the AIDA laser system has been modified, and this is not...
متن کاملExcimer Laser - Facilitated Coronary
Background. Excimer laser coronary angioplasty has been reported to be a promising treatment for complex coronary artery disease. The purpose of this study was to define the predictors of acute success and restenosis after this experimental intervention. Methods and Resuls. A cohort of 200 consecutive patients had a minimum of 6 months of follow-up evaluation after treatment of 215 coronary ste...
