摘要： Surface roughness having intervals of several tens of nanometers to about a hundred micrometers in a solid surface is reduced by directing a gas cluster ion beam to the surface. An angle formed between the normal to the solid surface and the gas cluster ion beam is referred to as an irradiation angle, and an irradiation angle at which the distance of interaction between the solid and the cluster colliding with the solid dramatically increases is referred to as a critical angle. A solid surface smoothing method includes an irradiation step of directing the gas cluster ion beam onto the solid surface at an irradiation angle not smaller than the critical angle. The critical angle is 70°.

摘要： In a method of irradiating a gas cluster ion beam on a solid surface and smoothing the solid surface, the angle formed between the solid surface and the gas cluster ion beam is chosen to be between 1° and an angle less than 30°. In case the solid surface is relatively rough, the processing efficiency is raised by first irradiating a beam at an irradiation angle θ chosen to be something like 90° as a first step, and subsequently at an irradiation angle θ chosen to be 1° to less than 30° as a second step. Alternatively, the set of the aforementioned first step and second step is repeated several times.

摘要： Scratches or similar surface roughness in a solid surface is reduced by gas cluster ion beam irradiation. A method of smoothing a solid surface with a gas cluster ion beam includes an irradiation step in which the solid surface is irradiated with a gas cluster ion beam, and the irradiation step includes a process of causing clusters from a plurality of directions to collide with at least an area (spot) irradiated with the gas cluster ion beam on the solid surface. Collision of the clusters from a plurality of directions with the spot is brought about by an irradiation of the gas cluster ion beam in which flight directions of the clusters diverge with respect to a center of the beam, for example.

摘要： A solid surface is processed while corner portions of a relief structure are protected from deformation. A method of processing a solid surface with a gas cluster ion beam includes a cluster protection layer formation step of forming, on the solid surface, a relief structure having protrusions with a cluster protection layer formed to cover an upper part thereof and recesses without the cluster protection layer; an irradiation step of emitting a gas cluster ion beam onto the solid surface having the relief structure formed in the cluster protection layer formation step; and a removal step of removing the cluster protection layer. A thickness T of the cluster protection layer satisfies T > nY + ( b 2 ⁢ Y 2 ⁢ n - nY 2 ⁡ ( b 4 - 16 ⁢ a 2 ) 1 2 2 ) 1 2 , where n is a dose of the gas cluster ion beam, and Y is an etching efficiency of the cluster protection layer, expressed as an etching volume per cluster (a and b are constants).
