Title: Tunnel transistor
Inventor: KIMURA MITSUTERU
IPC: H01L29/06
Filed: 1993-09-24
Abstract: PURPOSE:To decrease the influence of interface level of a MOS by adding the impurity of a conductivity type, that is different from the conductivity type of the semiconductor of the region the storage layer is formed, to the region near the surface of the semiconductor direct under the gate electrode. CONSTITUTION:A high density added layer 3 is formed by forming a thick SiO2 film 20 on a surface of n-type Si substrate 1 with the impurity density of 1X10<17>cm<-3>, opening a window and implanting boron ions shallowly in high density (5X10<19>cm<-3>). The layer 3 becomes p-type semiconductor layer and becomes different conductivity type from the n-type Si substrate 1. Then a thin SiO2 film is formed direct under the gate electrode. With the existence of the high density p-type impurity layer 3, the electric potential with respect to electrons at the region of n<+> storage layer 5 near the interface of the MOS is increased and the tunnel current that flows through the Shottkey junction 6 flows mainly n<+> storage layer 5 region of the n-type semiconductor near at the smallest part of the lower edge of a conductor. Therefore, the tunnel current flows the region a little distant from the interface level of the MOS interface and the influence of the interface level is decreased.

Title: Loop gain control device
Inventor: OGAWA NOBUYUKI
IPC: G11B21/10
Filed: 1987-09-22
Abstract: PURPOSE:To fix loop gain without deteriorating the leading-in characteristics of system by detecting a resonance value level of a loop characteristic, comparing a detecting signal with a reference voltage and then controlling a voltage control amplifier arranged in a loop through a limiter circuit. CONSTITUTION:Since no peak exists in a loop immediately before the start of control or at the time of generating tracking-out, the output of a voltage comparator 7 is oscillated up to the maximum driving capacity of a circuit, so that the voltage control amplifier VCA 8 can be set up to the maximum gain. Since the loop is turned to an unstable state and the loop can not be easily led in at the time of starting the control or at the time of releading, the VCA 8 is restricted to a control voltage for the VCA 8 whose gain can be reled by a limiter circuit 12. Even when the tracking loop is set up to any state, the releading can be stabilized and the loop gain can be also stabilized.
