IPC: H01L21/336
Filed: 1991-02-13
Abstract: PURPOSE:To improve throughput and yield through reduction of photolithography process by patterning both i-type semiconductor layer and an etching stopper in the first cycle of the photolithography process. CONSTITUTION:A dummay layer 10 is patterned to shape of an island corresponding to the desired shape of an i-type semiconductor layer 4. A lower layer is etched using such dummy layer 10 as a mask material. In this case, a thin stepped region of the dummy layer 10 is removed by the etching more quickly than the other region of the dummy layer 10 and the etching proceeds at the lower layer of the removed region. When the etching stopper layer 5 of the stepped region is removed perfectly and the i-type semiconductor layer 4 is exposed, the etching is stopped. As explained above, an etching stopper layer 5 is left in the shape of mask at the region other than the stepped region and simultaneously the region other than the mask of the dummy layer 10 is removed up to a semiconductor layer by the etching.

Filed: 1979-04-06
Abstract: PURPOSE:To prevent a grandchild ghost signal component, which may cause malfunction, from being generated near a reference waveform, by holding at a fixed level a constant section preceding the head position of the reference waveform of an input signal. CONSTITUTION:Switch 22 is normally placed at the (1) side to send out 28 a TV signal from input 21 as it is. Level holding circuit 27, on the other hand, samples and holds the current level, i.e., pedestal level of the TV signal by sample pulses P3 sent from delay unit 26 100mu sec after the start point of the 1st field. Thus, even if a TV signal including a ghost signal would be input to terminal 21, a TV signal can be obtained at terminal 28 which is held at the pedestal level in a section of about 60-70mu sec in an equalized pulse period preceding the rise (head position) of a vertical synchronizing signal used as the reference signal, so that any grandchild ghost component will not appear at terminal 28 at all.

Filed: 1980-04-01
Abstract: PURPOSE:To prevent an ineffective use of the telephone network, by receiving the signal transmitted from a telephone circuit network controller of a faulty electronic computer or the like at the telephone circuit network controller of one side and thus controlling the working of automatic dialing. CONSTITUTION:When the communication becomes impossible due to a fault of an electronic computer or the like, the call signal arrives at the terminals L1 and L2 of a telephone circuit to detect the fault through the incoming detecting part 1. As a result, the relay CML works to switch the contacts cml<0> and cml<1> for closure of the communication line. On the other hand, the relay TR works, and at the same time the communication incapability information signal is sent to the telephone circuit from the communication incapability signal sending part 5. This signal is detected by the opposite telephone circuit network controller and through the information incapable signal detecting part 4, and this output is sent to the alarm controlling part 7. Thus an alarm is given to the external operation board through the terminal RA, and at the same time the signal is sent to the automatic calling level converting part 8 to turn on the interface signal DLO. Thus an automatic dialing action is inhibited.
