Abstract
Clamped semiconductor wafers and clamped semiconductor devices include reservoirs filled with a flowable metal which hardens to allow the wafers/devices to be shipped or stored. The hardened metal may also be reflowed to a liquid to allow clamping of the semiconductor wafers together and to allow clamping of the semiconductor packages together. The flowable metal may be filled into the reservoirs as a liquid or paste. Thereafter, the flowable metal may be cooled to harden the flowable metal into a clamping member.
