Title: Manufacture of thin film semiconductor device
Inventor: TAKENAKA SATOSHI
IPC: H01L29/786
Filed: 1991-04-19
Abstract: PURPOSE:To inhibit a reduction in an ON current by eliminating an exposed portion of a gate oxide film with a gate electrode and a source/drain region as a mask, using the gate electrode and the source/drain region as a mask, adding impurity elements to an exposed portion of a non-single crystal semiconductor thin film and forming an offset region. CONSTITUTION:A gate electrode 1-11, a source contact region 1-12, a drain contact region 1-13 are used as a mask. An exposed portion of a gate oxide d film is removed by etching so that a non-single crystal semiconductor thin film may be partially exposed. Then, low concentration impurity elements are added thereto, thereby forming an offset region 1-14. More specifically, the gate electrode 1-13, the source contact region 1-12 and the drain contact region 1-13 are used as a mask so as to form the offset region 1-14 in a self-alignment fashion.

Title: Manufacture of semiconductor device
Inventor: MURAKAMI KAORI
IPC: H01L21/3065
Filed: 1986-04-17
Abstract: PURPOSE:To remove the variation of an output from a light-emitting diode and the error of detection of the end point of etching due to the fatigue of an etchant, and to improve the precision of etching by using a reference wafer consisting of the same substrate as a substrate for a monitor wafer carrying a material to be etched as a substrate for reference and simultaneously irradiating the reference wafer and the monitor wafer by light beams. CONSTITUTION:When both wafers are fitted so as to be simultaneously irradiat ed by light beams from a light-emitting diode 3 and a power-ON reset circuit 72 is set at the same time as the start of etching, an output signal R on the reference wafer side reaches VR while an output signal M(V1) on the monitor wafer side takes 0 first and is increased gradually as etching progresses and reaches V1>=VR in a short time. In this case, a signal is outputted from a compa rator 6, and an end-point signal is outputted from a flip-flop circuit 7. A signal transmitting the end of etching is emitted at a point of time when a fixed time set to an overetching timer 73 is added to a time when the end-point signal is emitted.

Title: Supersonic endoscope device
Inventor: MATSUI KOICHI
IPC: A61B8/12
Filed: 1988-04-14
Abstract: PURPOSE:To remove noise mixed into a receiving signal by specifying the length of respective signal cable parts, to which a signal cable is divided so as to supply the receiving signal, and passing only a frequency component, which is lower than the noise mixed into the receiving signal, in an observing device. CONSTITUTION:A transmitting signal supplied from a transmission timing generating circuit in an observing device 4 is converted to a voltage which is enough to drive a supersonic oscillator 1 with a transmitter 2. When the transmitting signal is received, the supersonic oscillator 1 radiates a supersonic wave around the tip of an inserting part and converts the supersonic wave, which is reflected and returned from a tested body, to an electric signal. This electric signal is amplified by a receiving amplifier 3 and passed through a signal cable 10, a transformer 5 and a signal cable 11. Then, the signal is amplified again by an amplifier 6. In such a case, a length (l) of the respective signal cables 10 and 11 has the relation of f<C<4l to a peculiar frequency (f) of the supersonic oscillator 1. (in the expression, c is a light speed). Thus, the signal of no noise is outputted from an LPF 7 and a supersonic picture is constructed in a picture processing circuit 8 and projected on a CPT 9.

SOLUTION: In this semiconductor memory, a read-out parasitic current is made to flow through a non-selection dummy virtual GND line, and a read-out parasitic current is prevented to be made to flow through a read-out bit lien and a read-out virtual GND line. Therefore, a parasitic current is not made to flow through a selection bit line, a read-out current of a selection bit line is increased, not only stable read-out opeartion of a memory cell is realized, but a high speed read-out operation can be performed. Also, as a read-out current of a selection bit line is increased, the number of banks connected to a main bit line can be increased, the memory division is decreased, and the chip size can be reduced.
