PRODUCT DESCRIPTION FEATURES APPLICATIONS Low Shrinkage Minimal Cloudiness High Stability Diverse Functionality Non-Contact Drawn Formation Non-Contact Annealing No Surface Defects No SiO Coating Needed Standard Thickness 0.70mm HOYA's NA-35 is an alumino silicate glass with excellent thermal characteristics. It displays minimal surface cloudiness from contact with fluoric acid and is ideal for device substrates requiring high deposition temperature or fine patterning, such as poly- Si TFT and EL. Flat Panel Displays Diode Liquid Crystal Displays Masks Sensors LOW SHRINKAGE NA-35 exhibits lower thermal shrinkage in high temperature heat treatment, even when compared to borosilicate glass. The NA-35's softening point is at 650°C, so its stability in shape and measurement during extremely high heat treatment (~600°C) makes it ideal for substrates of devices that require high process temperatures and patterning accuracy. It also has superb heat resistant characteristics, due to its low CTE at ~37 x 10 /°C. -7 MINIMAL CLOUDINESS The NA-35 is almost impervious to fluoric acid solution and exhibits minimal cloudiness when washing process using HF, NH F, HF-4 HNO3 , or HF-NH4 F. CONSISTENCY Our facility is designed to handle and monitor all aspects of glass making. We melt and form, anneal, cut and chamfer, polish and inspect, all in-house. Due to this streamlined manufacturing process, we are able to maintain a very low level of defects. 2 Non-Alkali, Flat Panel Glass HOYA CORPORATION USA Optics Division 3400 Edison Way Fremont, CA 94538 800-818-HOYA (4692) 510-252-8370 510-490-1988 fax www.hoyaoptics.com NA-35/32R Alumino Silicate Glass
