Patent ID: 7144618

Claim:
A multilayer composite comprising: an insulating substrate; and patterned conductive layers and insulating layers alternately laminated on the insulating substrate to define a laminate; wherein at least one of the insulating layers defines a correcting insulating layer including vitreous silica and quartz; the ratio of vitreous silica to quartz in the correcting insulating layer such that the thermal expansion coefficient of the correcting insulating layer differs from that of the insulating layers that do not define the correcting insulating layer, such that the correcting insulating layer corrects the warpage of the laminate attributed to a difference in thermal expansion coefficients between the insulating layers that do not define the correcting insulating layer, the patterned conductive layers, and the insulating substrate; and each of the insulating layers including the correcting insulating layer are composed of the same materials, and the only difference between the correcting insulating layer and the remaining insulating layers is the ratio of vitreous silica to quartz.
