Title: Measuring method for semiconductor device
Inventor: SUZUKI KOUICHI
IPC: G01R31/26
Filed: 1978-03-13
Abstract: PURPOSE: To decide whether the added element or the gate insulator film is impaired for the MOSFET containing the added element such as the diode or the like between the gate and the source by measuring the presence or absence of the current between the gate and the source while applying the bias between the drain and the source.  
     CONSTITUTION: Diode D 1  (an added element) is connected between source S and gate G of one side, and diode D 2  is connected between gate G 2  of the other side and source S respectively. In such dual gate MOSFET, voltage source VDS and ammeter AD connected in series are connected between S and drain D. At the same time, variable voltage VG l  is connected between 1st gate G 1  and S, and ammeter AG is connected between 2nd gate G 2  and S respectively. Then the current is flown from VDS and VG l  to measure the current flowing to ammeter AG to be then compared with the leak current of the normal FET oxide film. Thus, the impairment of the oxide film can be known easily.

Title: Method for driving variable wavelength semiconductor laser and variable wavelength light source device
Inventor: KATO TOMOAKI
IPC: H01S5/0625
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To suppress the wavelength instability of a variable wavelength semiconductor laser, caused by the hopping of an oscillation axial mode which occurs when the single axial mode laser oscillation wavelength of the semiconductor laser is switched. SOLUTION: When the oscillation mode of a variable wavelength semiconductor laser, having an active region and a wavelength control region is switched to a single axial mode laser oscillation wavelength λ2 from a single axial mode laser oscillation wavelength λ1, a waveform control current (λ-Control) is switched to I2 from I1. In the moments before and after the switching is performed, the current flowing to the active region (active) is made smaller than all threshold currents ITH in the oscillation axial mode which exist between the wavelengths, so as to stop the single axial mode laser oscillation of the semiconductor laser by at least a period of time longer than the lives of carriers in the wavelength control region.
