摘要:
Disclosed is a method for forming a polycrystalline silicon film of a polycrystalline silicon thin film transistor. The method includes a step of crystallizing an amorphous silicon film deposited on a glass substrate by irradiating a laser beam onto the amorphous silicon film using a mask pattern. The glass substrate is horizontally moved by a predetermined distance unit corresponding to a translation distance of the mask pattern when the laser beam is irradiated onto the amorphous silicon film through a mask having the mask pattern, thereby growing grains in a circular shape.

A microelectronic element such as a semiconductor chip has springs such as coil springs bonded to contacts so that the springs serve as electrical connections to a circuit panel. The unit can be tested readily and can be surface-mounted to a circuit panel by bonding the distal ends of the springs, remote from the microelectronic element, to the panel. The springs can also serve as antennas so as to provide a miniaturized phased array.

A multilayer, three-dimensional wiring matrix is fabricated from a plurality of individually testable plane pair sub-units (30). Each of the plane pair sub-units (30) includes a compensator (20) with capping layers (32) laminated on either side. The compensator (20) has a dielectric (14) encapsulated foil (10) which has been patterned with holes (12). Metallization patterns on the surfaces of the compensator (20) provide orthogonal wiring (22), electrical connections (24) to the foil (10), and electrical connections (26) between the top and bottom surfaces. The capping layer (32) includes joining metallurgy (38) at selected locations within a dielectric layer (36) that is in registry with the metallization in the vias (16). The joining metallurgy (38) may be a metal loaded thermoplastic and provides a seal for the vias (16) as well as planarizes the structure. The capping layers (32) may be formed in-situ on the compensator or separately.
