Title: Terminal line changeover device
Inventor: KITO KAZUAKI
IPC: H04B3/46
Filed: 1992-09-28
Abstract: PURPOSE:To reduce manufacture cost by providing a transmission section continuously sending control data outputted from a control section, a reception section reproducing received data while dividing the data for each prescribed bit and a discrimination section identifying the content to the changeover device. CONSTITUTION:After a transmission signal is sent from other line changeover device to a standby line 19 being a terminal line and fed to a transmission reception section 7 via a relay 16, the signal is converted into control data by a reception data recovery section 9 and fed to a CPU 10 via a bus. Patterns resulting from rotating one bit each of the control signal are stored and the received control signal is compared with the rotated pattern. Since the pattern of the control signal is coincident with any of the patterns so long as the line is normal, the CPU 10 discriminates it that the reception signal received by the transmission reception section 7 is the signal. Thus, the establishment of synchronization other than bit synchronization is not required and the configuration of the line changeover device is simplified.

IPC: H01L29/786
Filed: 1988-11-10
Abstract: PURPOSE:To make it possible to use cheap glass substrates by resist-etching a gate electrode pattern on a gate insulating film, removing the gate insulating film using the gate electrode and resist as masks, laminating a doped layer all over the surface, then removing the resist and the doped layer on the resist together, and annealing them after a lift-off process. CONSTITUTION:A gate insulating layer 3 is patterned by dry etching using SF6/C2ClF5. Then, a doped layer 6 doped with P<+> boron ions is formed using silane gas containing 1% diborane(B2H6). Following that, resist is exfoliated through a lift-off method, and the doped layer 6 attached to the upper surface in a film is removed simultaneously. And, after a film of capping material 7 is attached annealing is performed in vacuum using an XeCl excimer laser. On this occasion, a gate metal functions as a mask and prevents a laser beam from striking the amorphous silicon under the gate electrode 4, and the influence on the channel section can be prevented. This makes possible the formation of source-drain electrodes without implanting ions, in a planar type in addition, and by a self-alignment system, and the formation of polycrystalline silicon under a low temperatures of 400 deg.C or less, as well.
