Our proprietary 99.6% formulation produces a fine-grain substrate with excellent surface finish and dielectric characteristics. Our substrate is ideal for thin-film applications with ultra fine-line resolution and spacing. Our current capability is producing substrates as large as 15"x 15". We are currently expanding our production capacity to make 36"x 36" substrates. Once we complete the expansion our substrates will be one of the largest manufactured substrates available.
Currently, we deliver substrates as-fired, as well as lapped and polished to a mirror-finish. We are capable of lapping CTAL-996 as large as 36"x 36" and parts as thin as 0.0005" (12.5 micrometers.) We can polish our CTAL-996 substrates as smooth as 20 Angstroms-Ra.
