Abstract
A constraining ring increases the modulus of an interconnect substrate to maintain flatness of the substrate. The constraining ring is made of materials selected to match the coefficient of thermal expansion of the substrate to that of the constraining ring. Circuit components including capacitors and resistors are formed on the constraining ring to provide enhanced electrical properties without adding to the size of the device.
