A method for mounting a dielectric substrate to a semiconductor substrate, such as mounting a dielectric antenna substrate to an MMIC semiconductor substrate. The method includes providing a thin dielectric antenna substrate having metallized layers on opposing sides. In one embodiment, carrier wafers are used to handle and maintain the dielectric substrate in a flat configuration as the metallized layers are patterned. The dielectric substrate is sealed to the semiconductor substrate using a low temperature bonding process. In an alternate embodiment, the metallized layers on the dielectric substrate are patterned simultaneously so as to prevent the substrate from curling.
