Laser assisted particle removal from Silicon wafers
We have studied the removal of submicrometer particles from silicon wafers by the steam laser cleaning (SLC) and dry laser cleaning (DLC) processes. These processes are currently being investigated as new promising cleaning technologies for complementing traditional methods in industrial applications. For SLC a thin liquid layer (e.g. a water-alcohol mixture) is condensed onto the substrate, an...
متن کاملBehavior and effects of fluorine in annealed n¿ polycrystalline silicon layers on silicon wafers
A comprehensive study is made of the behavior and effects of fluorine in n-polysilicon layers. The polysilicon is deposited in a conventional low pressure chemical vapor deposition furnace on ~100! silicon wafers, implanted with 1310 cm F and 1310 cm As and annealed at 850, 950, 1015, and 1065 °C. Sheet resistance, transmission electron microscopy ~TEM!, and secondary ion mass spectroscopy are ...
متن کاملLaser cleaning of particles from silicon wafers: capabilities and mechanisms
Introduction The preparation of surfaces free of particle contamination is one of the crucial prerequisites for a further increase in the integration density of ICs and for the progress in nanotechnology. Therefore the removal of sub-micron sized particles from silicon wafers is of great interest. For this purpose a variety of cleaning methods is currently under investigation. In semiconductor ...
متن کاملUltraviolet laser removal of small metallic particles from silicon wafers
Laser removal of small 1mm sized copper, gold and tungsten particles from silicon wafer surfaces was carried out using ultraviolet radiation at 266 nm generated by Nd:YAG harmonic generation. Successful removal of both copper and gold particles from the surface was achieved whereas tungsten particles proved to be difficult to remove. The cleaning efficiency was increased with an increase of las...
متن کاملLaser Cleaning of Silicon Wafers: Mechanisms and Efficiencies
We report on experiments on the underlying physical mechanisms in the Dry(DLC) and Steam Laser Cleaning (SLC) process. Using a frequency doubled, Q-switched Nd:YAG laser (FWHM=8 ns) we removed polystyrene (PS) particles with diameters from 110-2000 nm from industrial silicon wafers by the DLC process. The experiments have been carried out both in ambient conditions as well as in high vacuum (10...
