Abstract
Quarter-wave-shifted gratings were fabricated by novel methods using ECR-CVD SiN, films. SiNx films deposited on photoresist and grooves have a higher etching rate than those deposited on the flat substrate. We made good use of this difference to fabricate the quarter-wave-shifted gratings with a 240 nm period, about 150nm depth and narrow transient regions.
