  • Patent number: 5518572
    Abstract: An etching system contains a plasma chamber, a charge exchange chamber and a processing chamber. The charge exchange chamber and the processing chamber are partitioned with a porous plate provided with a number of fine linear microchannel holes. Positive ions generated by the plasma chamber are accelerated by an accelerating electrode in the charge exchange chamber, charge-exchanged and introduced as neutral particles through the microchannel holes into the processing chamber. Neutral particles are vertically entered into an object to be processed as neutral particle beams that are completely aligned by the microchannel holes. An object with a large surface area can be etched with high accuracy by making the porous plate a size which corresponds to the object. Thus, plasma processing with only neutral particles is carried out with high accuracy even when the surface area of the object is large.

  • Patent number: 4993038
    Abstract: As a beam converger, one having reflective surfaces including partial cylindrical curved surfaces and partial plain surfaces, which surround laser rod and pump lamp plane-parallelly and substantially uniformly in the axial direction thereof, is adopted, so as to make a high beam converging property in the case of adoption of an elliptic cylinder moderate. The axes of the pump lamp and/or the laser rod are shifted to positions closer to the partial cylindrical curved surfaces than the center lines of the partial cylindrical curved surfaces, so as to increase energy of light exciting the laser rod by the pump lamp, thus improving the efficiency. A laser system obtained by combining a resonant type laser device comprising two laser rods and one or two pump lamps with a prism having a regular equilateral triangle shape in cross section, highly contributes to the compactness and simplification of the laser system.
