In this paper, we report on the evaluation of the SiC X-ray mask distortion induced by the backetching receding fabrication process by experiment and simulation. The window-opening process for the backetching mask induced pattern displacements of abo

The SiN membranes were deposited by using high temperature LPCVD system. The SiN films deposited over 1000 degree(s)C showed the suitable properties for X-ray mask, such as well- controlled tensile stress of 5 X 10 7 Pa, high optical transmittance ov

The e-beam proximity effect is well known as one of the limiting factors in e-beam lithography. As features get smaller the need for e-beam proximity effect correction (EPC) increases. There exist different approaches to cover these effects by varyin

The influence of resist and absorber stress distributions on X-ray mask distortion induced during back-etching preceding subtractive fabrication is analyzed experimentally and simulated. The stress distribution (gradient) in a resist and/or that in a

SiC/SiN multilayer membranes consisting of SiC and thin SiN layers were prepared using hot-wall, low-pressure chemical vapor deposition (LPCVD) for synchrotron radiation (SR) lithography. The SiC/SiN multilayers had advantages such as uniformity in t

A new transverse‐mode‐controlled laser called a buried multiquantum‐well (BMQW) laser has been developed. In order to make it possible to bury the MQW laser active region utilizing the diffusion‐induced disordering (DID) of GaAs‐GaAlAs MQW,

We have developed a technique for improving X-ray irradiation stability of silicon nitride (SiN) X-ray mask membrane using H+ implantation. This technique can realize the reduction of X-ray irradiation-induced pattern displacement to less than 20 nm

Liquid oxygen and oxygen–argon mixtures were excited by 1.06-μm Q-switched Nd:YAG laser light. Fluorescence spectra were observed at wavelengths of 481, 637, 704, and 764 nm. Emission intensities showed a cubic dependence on the exciting Nd:YAG la
