Thin-Film Electronic Substrates
Why Ceramic Thin-Film Substrates?
CoorsTek is the leader in custom and standard thin-film ceramic substrates. Four thin-film substrate material options combine smooth surface finish, strong flexural strength, and consistent electrical properties. Contact CoorsTek to help you design a specific thin-film substrate for your application, or download our Design Guide.
Alumina is an optimal material for most thin-film ceramic substrate applications. CoorsTek controls surface finish, grain size, and surface imperfections to enhance fine-line resolution, spacing, and yields in your thin-film process. CoorsTek substrates are available in "as-fired" and finished form, and in both standard and resistor grades.
SuperStrate® Thin-Film Substrates
CoorsTek SuperStrate® substrates are the industry standard for high-performance, thin-film substrates — providing an exceptionally smooth surface finish for optimum fine-line definition. 
ADS-996 Thin-Film Substrates
CoorsTek ADS-996 alumina substrates are a workhorse for most thin-film electronics applications.
ADS-995 Thin-Film Substrates
Our ADS-995 alumina substrates are an economical alternative for less-demanding thin-film applications.
Substrate Size & Thickness
Substrate Thicknesses (Alumina)
CoorsTek offers thin-film substrate thicknesses from 0.127 mm (0.005") to 1.524 mm (0.060"). Standard as-fired thickness tolerance is ± 10%.
Substrate Sizes (Alumina)
CoorsTek offers a wide range of standard and custom sizes. Common square and disc sizes are shown below. Contact us if you need a custom size or geometry.
