Abstract
A process for fabricating a substrate for a radiofrequency device includes providing a piezoelectric substrate and a carrier substrate, depositing a dielectric layer on a surface of the piezoelectric substrate, assembling together the piezoelectric substrate and the carrier substrate with a polymerizable adhesive directly between the dielectric layer and the carrier substrate to form an assembled substrate, and polymerizing the polymerizable adhesive layer to form a polymerized layer bonding the piezoelectric substrate to the carrier substrate, the polymerized layer and the dielectric layer together forming an electrically insulating layer between the piezoelectric substrate and the carrier substrate.
