Filed: 1989-02-22
Abstract: PURPOSE:To make a P-N junction capacity small by a method wherein at least either a source part or a drain part in a switching MISFET is constituted of a low-concentration diffusion region and a high-concentration electrode is formed so as to come into contact with the diffusion region. CONSTITUTION:At least with a source part or a drain part in a switching MISFET 12 formed just under a main face of a semiconductor main body is constituted of low-concentration diffusion regions 16, 17; in addition, high- concentration electrodes 10, 11 composed of an epitaxial layer are formed so as to come into contact with the diffusion regions 16, 17. Accordingly, a depletion layer is spread largely; it is permitted that the depletion layer is spread inside the electrodes 10, 11 composed of the epitaxial layer; accordingly, it is possible to restrain the depletion layer from being spread to the side of the source part or the drain part. Thereby, it is possible to obtain a semiconductor device whose P-N junction capacity is small and in which a punchthrough phenomenon is hard to cause.

Title: Production of optical information recording medium
Inventor: OKAMOTO KAZUHISA
IPC: G11B7/26
Filed: 1987-02-25
Abstract: PURPOSE:To easily produce a stamper having no defect by directly cutting the stamper with a laser beam. CONSTITUTION:Material 3 for stamper set on a table 2 is arranged opposite to a laser head 4 which focuses the laser beam for cutting on the material 3 for stamper. The laser head 4 radiates the laser beam for cutting with moving the table 2 and the laser head 4 oppositely each other in a surface direction of the material 3 for stamper so as to directly cut the groove shaped pattern on the surface of the material 3 for stamper. Thus, the producing process of stamper can be remarkably simplified. And since the developing process of exposed original disk which easily generates the defect and fault and the electroforming process of stamper can be omitted, the non-defective unit of stamper can be remarkably improved. As a result, the optical information recording medium whose error rate is low can be easily produced at low cost.

A bias circuit 15 adds a bias voltage in which the detecting voltage E10 comes to be the zero voltage when the level of the sound input signal is zero and the signal inputted to the detecting device 13 is the noise component only. A bias circuit 35 adds the bias voltage so that the detecting voltage E30 can be the zero voltage when a sound signal component is not included in a reproducing signal and is a noise component only. Namely, at the sound signal compressing device 1 and the sound signal stretching device 3, the reduction of the linearity of the compression characteristic and the stretching characteristic due to the noise component will not occur even at the low level area of the input signal.

IPC: G11C11/22
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To provide a ferroelectric memory device which can achieve sure and high speed operation with low power consumption and comparatively easy control. SOLUTION: This ferroelectric memory device can transfer the voltage of a bit line bar 28 amplified by a sense amplifier 30 to a plate line 35 by connecting a plate line 35 and the bit line bar 28 with a NMOS transistor 54 (switch means).
