Latest Patents

Kise's latest patents include an innovative X-ray mask. This invention aims to suppress the reduced transmittance of the X-ray absorber while achieving a phase shift amount close to π-radians. The design utilizes a material with high transmittance per film thickness, incorporating elements that provide both high phase shift amounts and low transmittance. This unique composition ensures that the transmittance is primarily determined by the element with low transmittance, while the phase shift is compensated by the high transmittance element.

Another notable patent involves an exposing method and semiconductor device fabricated by this method. This technique reflects synchrotron radiation with a critical wavelength of 8.46 Å, emitted from a radiation generator. The method includes the use of rhodium mirrors and a beryllium window, allowing for precise irradiation of a resist surface on a substrate. The resist is designed to absorb light within a specific wave range and contains elements that generate Auger electrons upon exposure.
