Patent JP-H09232563-A (JP)
Title: Field-effect transistor
Inventor: YANAGAWA HIROSHI
IPC: H01L29/78
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To reduce the threshold voltage by providing impurity concentration distribution in the direction of depth of a well of one conduction type such that the maximum concentration is observed at a part deeper than a surface layer. SOLUTION: Ion implantation of n-type impurity and then thermal diffusion thereof are performed on a main surface 21a of a semiconductor substrate 21 of one conduction type, thereby forming a well 22 of another conduction type. Ions of p-type impurity are implanted into the surface of the n-well 22, thereby forming a p-well 23. The impurity concentration of the p-well 23 is constant in the lateral direction and variable in the direction of depth so that the maximum concentration is observed at a junction portion 23a. A source 24 is formed on the surface of the p-well 23, and a drain 25 is formed on the surface of the n-well 22 which is away from the p-well 23. A gate electrode 27 is formed on the surface of the p-well and the n-well between the source 24 and the drain 25 of the p-type silicon substrate 21.  A source electrode 29 is formed on the source 24, and a drain electrode 30 is formed on the drain 25. Finally, a field oxide film 28 is formed thereon. Thus, irregularity in threshold voltage may be reduced.

IPC: G01B21/00
Filed: 1984-02-24
Abstract: PURPOSE:To prepare the quality control data with the arbitrary number of the data, by setting the upper limit value and the lower limit value of preset size based on the reference value of a material to be measured and the number of divisions, by which the range of the preset size is divided equally, and memorizing the frequencies of the measured data belonging to the divided sections.

Title: Sample heating apparatus and sample heating/cooling system
Inventor: SUZUKI KATSUYUKI
IPC: H01J37/20
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To prevent the breakage of a piezoelectric element of a scanner even when a sample is heated at high temperatures for many hours. SOLUTION: When a sample 5 is heated by a heating power supply 8 at high temperatures, the heat of the sample 5 is conducted to a fixed stand 7 through a heat conductor 9. Since the fixed stand 7 has a sufficient thermal capacity, the conducted heat is certainly absorbed and released outside. On the other hand, the heat conducted to the heat conductor 9 out of the sample 5 is not conducted toward a scanner 6 by the presence of a thermal insulator 10. Therefore, even though the sample is heated at high temperatures for many hours, the temperature of the scanner 6 will not increase, and the polarization of a piezoelectric element constituting the scanner 6 cannot be broken.

IPC: G01J3/28
Filed: 1983-02-28
Abstract: PURPOSE:To form a spectrophotometer wherein ranges are automatically set appropriately, by setting the range of a recorder so that the maximum and minimum values of spectrums, which are detected from the memorized data of the measured value for every wavelength within a specified wavelength region, are accomodated just right within the upper and lower limits of the recorder, and reading and recording the stored data. CONSTITUTION:A central processing unit 2 positions a spectrophotometer at one end of the specified wavelength region to be measured. From this position, wavelength scanning is started. The measured value of the optical spectrum is sampled every time the wavelength is increased by a specified wavelength width, and AD conversion is performed. The result is sequentially stored in an RAM3. When the spectrophotometer reaches the other end of the wavelength region to be measured, the wavelength increase of the spectrophotometer is stopped. Then, the measured data of the spectrum stored in the RAM3 are sequentially read out, and the maximum and minimum values are detected. The central processing unit selects the range of a recorder 6 from the maximum and minimum values, sequentially reads the data of the spectrum stored in the RAM3, and makes the recorder 6 to record the spectrum in the selected range.

Filed: 1983-03-04
Abstract: PURPOSE:To transfer a signal with high accuracy even in case when a line resistance is large by constituting so that a current distortion generated by a voltage detector is cancelled by a voltage generator. CONSTITUTION:In a voltage/current converting circuit by a resistance RB and a current mirror 5, a current distortion is generated due to non-linearity of an input resistance of the current mirror 5. A signal current containing this distortion is inputted to a current/voltage converting circuit 9 consisting of a transistor TR9 and the resistance RE through a current mirror 7. A mirror ratio of the current mirrors 5, 7 is all set to ''1'', the resistance RE and RB are set to the same resistance, and when the TR9 and an input TR of the current mirror 5 use those of the same shape, non-linearity of the input of the current mirror 5 and non-linearity between the base and the emitter of the TR9 become almost equal, therefore, the current distortion generated by the current mirror 5 is cancelled by the TR9. The same way is formed between a current mirror 6 and a TR8, as well.
