The best ceramics
yield the best results.

AdTech Ceramics is the leading manufacturer of custom designed multilayer aluminum nitride substrates. Aluminum nitride offers high thermal conductivity with an excellent coefficient of thermal expansion (CTE) match to silicon. The material system is stable from cryogenic to high temperatures making it ideal for imaging applications as well as high power amplifier multichip modules and heater applications.

Using patented hot press technology, AdTech Ceramics is able to offer multilayer MCM substrates up to 4.5" (114.3mm) square with hermetic via positional tolerances of +/- .15%. Flatness can be held within .0002" (5um) and additional mechanical features can be machined using diamond and/or ultrasonic tools. Surface metal is applied using industry standard photolithography and etching techniques providing a variety of metallization options to meet application requirements.
