Can zinc aluminate-titania composite be an alternative for alumina as microelectronic substrate?

ABSTRACT: Alumina, thanks to its superior thermal and dielectric properties, has been the leading substrate over several decades, for power and microelectronics circuits. However, alumina lacks thermal stability since its temperature coefficient of resonant frequency (τ_f) is far from zero (-60 ppmK^-1). The present paper explores the potentiality of a ceramic composite 0.83ZnAl₂O₄-0.17TiO₂ (in moles, abbreviated as ZAT) substrates for electronic applications over other commercially-used alumina-based substrates and synthesized using a non-aqueous tape casting method. The present substrate has τ_f of + 3.9 ppmK^-1 and is a valuable addition to the group of thermo-stable substrates. The ZAT substrate shows a high thermal conduct
