摘要
The radiation stability in silicon nitride (SiN) membranes for synchrotron radiation (SR) lithography has been investigated in a helium ambient, using scanning-mirror exposure method. It was found that the displacement along the y-axis of an SiN membrane is larger than that along the x-axis. A mirror was oscillated along the y-axis in order to obtain a 30 mm square irradiation, thereby producing the variation in the SR spectrum absorption difference in the membrane, especially in the wavelength region below the silicon absorption edge (0.67 nm in wavelength), although an SR power per unit area was given on a resist almost uniformly. As a result, it is considered that this SR spectrum absorption difference causes larger displacements along the y-axis of the SiN membrane.
