摘要:
Disclosed herein is a method for forming a polycrystalline (poly-Si) film by the crystallization of an amorphous silicon film using laser light irradiation. The disclosed method comprises the steps of: sequentially depositing a buffer film and an amorphous silicon film on a glass substrate; depositing a metal film having laser light reflection function on the back side of the glass substrate; and irradiating the front side of the amorphous silicon film with laser light to crystallize the amorphous silicon film. In the laser light irradiation step, the irradiated laser light is absorbed into the amorphous silicon film, and a portion of the absorbed laser light is transmitted through the amorphous silicon film. The transmitted light is reflected from the metal film and absorbed into the amorphous silicon film again, thus crystallizing the amorphous silicon film twice over. According to the present invention, the amorphous silicon film is crystallized twice over so that a polycrystalline film having very large grains can be formed.

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 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.

A sensor measuring skin impedance includes a reference electrode, a current carrying electrode, and a measuring electrode for measuring impedance for current flowing between the reference electrode and the current carrying electrode. The measuring electrode is recessed with respect to the reference electrode and the current carrying electrode, allowing the measuring electrode to make contact with a user's skin after the reference electrode and current carrying electrode make contact, resulting in greater measurement accuracy.
