摘要:
A communications network employs an optical communications medium carrying a synchronous communications transport signal including a number of time-division-multiplexed (TDM) channels. A number of bridges include respective interfaces to associated local area network (LAN) segments, and the bridges are coupled to the communications medium by associated add-drop circuits. Each add-drop circuit groups the TDM channels of the transport signal into bundles, each bundle being associated with a different bridge. Each add-drop circuit transmits data traffic originated by the associated bridge on only the bundle associated with the bridge, receives data traffic from the other bridges via the bundles associated with the other bridges, forwards the received data traffic to the associated bridge, and re-transmits at least some of the received data traffic on the bundles for receipt by another of the add-drop circuits.

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.
