on a semiconductor package, the linear distance between the edge of a cavity cut into a layer of ceramic and the first measurable glass or metallization layer interface coated onto the top surface of that layer. The total pullback may be the result of the high temperature processing required to manufacture the package or to coat the surface. It may also be the result of design considerations. [SEMI G61-94]
