IPC: H01L29/744
Filed: 1978-02-22
Abstract: PURPOSE: To perform excellent GTO operation without doping life time killer.  
     CONSTITUTION: In the substrate of pEnBpBnE construction, the main electrodes 6 and 7 are contacted in low resistance with pE and nE and the control electrode 8 is  to pB. When pEnB is shortened with the electrode 6, the current amplification factor of the transistor T 1  is decreased, and effect to pick up the storage carrier of nB to the electrode 6 is expected. Short-circuit resistance RSO=KρW requires for the suitable relinquishment. Where K is a factor of shape due to nE layer pattern, ρ is the resistivity of nE layer, and W is the thickness of nE layer. Further, since the storage time t s  is dependent on the carrier life τB and K, τB is calculated from the desired t s  of objective GTO and K is calculated. On the other hand, the size of each layer can be determined by obtaining ρ, W and RSO from the dielectric strength. With this method, the addition of the life time killer is unnecessary, then the forward voltage drop and the leakage current are less and the turn off performance can not be lowered at high temperatures.

Title: Formation of metallized layer of pedestal for semiconductor pressure sensor
Inventor: SAITO HIROSHI
IPC: H01L29/84
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a method by which the metabolized layer of a glass pedestal for semiconductor pressure sensor having high junction reliability can be formed without forming the metallized layer on the internal surface of the glass pedestal nor increasing the number of processes. SOLUTION: The metllized layer 8-forming surface side of a glass pedestal 2 is joined to a metallic pipe 4 through solder 9, and the opposite-side surface of the pedestal 2 is anodically jointed to a semiconductor pressure sensor chip 1. When the anodic joining is performed under such a condition that the pedestal 2 and the chip 1 are heated to about 400 deg.C in a vacuum atmosphere and a DC voltage is applied across the pedestal 2 and the chip 1 so that the chip 1 side may become the anode side, the pedestal 2 and the chip 1 are atomically joined to each other by an electrostatic attracting force. Since pins are respectively inserted into the through holes 21 of the pedestal 2 during process of forming the metallized layer 8, the layer 8 is not formed on the internal surfaces of the holes 21, but only on the joining surface for the metallic pipe 4.  Therefore, when the pedestal 2 and the chip 1 are anodically joined to each other, the chip 1 is not broken by discharge.

Title: Digital filtering arithmetic method and digital filter
Inventor: TOYODA TAKASHI
IPC: H03H17/04
Filed: 1994-02-16
Abstract: PURPOSE:To prevent signal quality from being deteriorated even when a sufficient arithmetic word length cannot be obtained by providing a random number generator to the filter, giving a random number signal from the random number generator to a cyclic arithmetic section as another input signal, adding an input signal and the other input signal thereat, and applying addition/subtraction processing of a random number signal to the summed signal at a post-stage. CONSTITUTION:An amplitude of an input signal is sufficiently increased more than a quantization error generated in a cyclic arithmetic section by superimposing a 2nd input signal I2 being a random number signal to a 1st input signal I1 at the cyclic arithmetic section. A sufficient variance is provided to the generated quantization error. That is, the distribution of the quantization error to be produced is close to a uniform distribution by the random number component. Since a random signal is subtracted, that is, a random number signal multiplied with -1 is added at a post- stage to the signal with the random number signal superimposed thereon at the cyclic arithmetic section in this digital filter, the superimposed random number signal is cancelled. Thus, a digital filter output preferably in terms of sound quality is obtained from an output terminal 23 only with a small reduction in a gain to the substantial input signal I1 received by an input terminal 21.
