Abstract
Devices and methods useful for testing bare and packaged semiconductor dice are provided. As integrated circuit chips become smaller and increasingly complex, the interface presented by a chip for connectivity with power supplies and other components of the system into which it is integrated similarly becomes smaller and more complex. Embodiments of the invention provide micron-scale accuracy alignment capabilities for fine pitch device first level interconnect areas. Embodiments of the invention employ air-bearings to effectuate the movement and alignment of a device under test with a testing interface. Additionally, testing interfaces comprising membranes supported by thermal fluids are provided.
