Hi, I'm looking a merchant to make a 4" soda-lime glass plate mask set, 6 layers, each layer's reticle size is 2.1x2.3 cm. Smallest feature size is 5 um. The quote I got from HTAphotomask is $350.00 per mask totalling to 6x350=$2,100.00. I'm checking to see whether there's anything cheaper. Thanks! Archy archyx@udel.edu
