Title: Method of making characteristic of silicon oxide film interface uniform
Inventor: ITO TAIZO
IPC: G01N22/00
Filed: 1988-03-26
Abstract: PURPOSE:To improve the in-line quality control of the manufacturing process of a semiconductor element by a method wherein the optimizing requirements for nitrogen atmospheric heat treatment of a thermal silicon oxide single crystal substrate are decided easily by the measurement of lifetime. CONSTITUTION:It is recommended that the lifetime of a thermal silicon oxide substrate in nitrogen atmosphere is measured by the microwave process as a noncontact process. The measurement system is composed of the implantation system to excite any excessive carriers and the microwave system to detect the change in conductivity of semiconductor substrate. The composite value taum of the lifetime taub of bulk and the lifetime taua of surface layer can be calcu lated by the following relation formula of 1/taum=1/taub+1/taum, where, if taua is much larger than taub, 1/taua can be neglected to assume taum=taub, i.e., taum=1/2taub. Thus, at least the status in interface can be regarded as that near the crystallizability of bulk. Consequently, the nitrogen heat treatment requirements can be decided to be optimum at the point when the measured value of lifetime is at the same level as that of the bulk and the level is not to be raised any more.

IPC: G01S13/28
Filed: 1986-03-31
Abstract: PURPOSE:To correct the scatter of characteristics and changes in the characteristics corresponding to changes in environmental conditions and stabilize the characteristics by storing signals to which a prescribed modulation is applied in advance as functional type coded signals, reading out them at prescribed periods, D/A-converting the signals and using them as modulated signals. CONSTITUTION:When receiving reference frequency signals, a control signal generator 2 generates transmitting intervals and a transmitting time. Control signals operate a counter 3 or 4 during the transmitting time and address a memory 5 or 6. Modulated signals thus read out are converted into analog modulated signals by a D/A converter 8, supplied to a frequency converter 9 to be converted to a required frequency, power-amplified by a power amplifier 10 and outputted to an antenna via a duplexer 13. Waves reflected and returned from a target object are amplified by a receiving amplifier 15 and its output is converted into intermediate frequency signals by a mixer 16. The intermediate frequency signals are pulse-compressed by a matched filter 17 and compressed signals are inputted to the compressed signal processing system of a radar instrument.

Title: Evaluating method of fluidity of material in power molding
Inventor: YOSHIDA TADATSUGU
IPC: G01N11/00
Filed: 1990-03-26
Abstract: PURPOSE:To evaluate the fluidity of a material in powder molding accurately and easily by a method wherein a thin film with a predetermined geometric pattern is placed into a powder material, and the material having the thin film embedded therein is molded. CONSTITUTION:A thin film 5 with a geometric pattern is embedded together with a material into a die which is comprised of a die mortar 1, an upper mallet 2 and a lower mallet 3. The color of the thin film 5 or the color and thickness of lines of the geometric pattern of the thin film 5 etc. are selected depending on the using material so as to facilitate the measurement after molding. In compression molding, the thin film 5 is tightly adhered to the material due to the compression stress generated in the material. As molding is proceeded, a flow of the material is brought about, so that the thin film 5 is deformed together with the surrounding material. If the thin film 5 is made of such raw material that has small internal rigidity with elasticity, the film is not broken even when the powdery material is greatly deformed. It is necessary to select a paint to draw the geometric pattern which is more easily adhered to the material than the thin film 5 when the pattern is desired to be transferred, and it is also required, for instance, to apply a paste or the like to one surface of the thin film 5 in order to make the paint selectively adhere to the one surface.
