Diamond Photodetector Response to Deep Uv Excimer Laser Excitation
Diamond photoconductive detectors have previously been shown to be suitable for detection of deep ultraviolet nanosecond-scale pulses from excimer lasers, which are to be used in next generation lithographic systems. Using simple test circuitry and low bias voltages easily measurable responses were observed when these detectors were illuminated with laser pulses at typical laser fluence levels....
متن کاملDeep-UV Excimer Lasers
The recent trend in microelectronics towards patterning critical feature sizes of 0.25 m and below has motivated the development of microlithography at the deep ultra-violet (DUV) laser wavelengths of 248 and 1 93 nm. In recent years the performance, reliability, and cost of ownership of excimer light sources have improved. Some key technologies needed for excimer lasers in microlithography inc...
متن کاملEffect of Thermal Preconditioning Before Excimer Laser Photoablation
The purposes of this study were to assess the expression patterns of heat shock proteins (Hsps), after eyeball heating or cooling, and to elucidate their relationships with corneal wound healing and intraocular complications after excimer laser treatment. Experimental mice were grouped into three according to local pretreatment type: heating, cooling, and control groups. The preconditioning was...
متن کاملEffect of the ArF excimer laser on human enamel.
Human enamel surface was irradiated with ArF excimer laser and examined under light microscopy and scanning electron microscopy (SEM). Enamel surface was irradiated at three different areas with different energy fluences. It is demonstrated that the ArF excimer laser causes ablation of the calcified hard enamel tissue. Ablation curves were measured. There was no significant difference found in ...
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...
