Patent JP-H11316981-A (JP)
Title: Production of optical information recording medium
Inventor: OKAMURA TATSUYA
IPC: G11B7/26
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To obviate variations in the film thicknesses of thin films by installing substrates into a sputtering space, introducing a sputtering gas therein, measuring the partial pressure of gas exclusive of the sputtering gas in the space in this state by a mass spectrometer and setting deposition conditions. SOLUTION: The substrates are put into the chamber and gaseous argon is introduced therein and in this state, the partial pressure of the water in the chamber is measured by a mass spectrometer. If the measured value X is below a prescribed value (2 μTorr), the deposition time is set at the prescribed time A (60 seconds). If the measured value X is larger than the prescribed value, the deposition on the respective substrates is executed in the deposition time Y calculated by substituting the prescribed time A and the measured value X with the equation. As a result, the change in the deposition rates by the difference in the state of every substrate may be corrected and, therefore, the variations in the film thicknesses may be decreased at the time of mass production to execute deposition on a multiplicity of the substrates.

IPC: H01J47/08
Filed: 1981-07-31
Abstract: PURPOSE:To achieve earier measurement starting time while preventing damage to a meter by discharging charged electric charge quickly through a clamp  circuit while clamping overvoltage therewith. CONSTITUTION:Ionization current generated from an ionization chamber 1 is amplified with an arithmetic amplifier 2 and a negative output current is generated to deflect a pointer of a meter 3. On the other hand, the arithmetic amplifier 2 is connected to the ground on the negative side of a power source 4 thereof via a series circuit of a variable resistance 5 and a diode 6 and two diodes 7 and 8 are connected to an output terminal thereof. When output voltage V0 of the arithmetic amplifier 2 is V0>V2-(VR+V1), it is clamped to V2-(VR+V1). When it is V0<V2-(VR+V1), the output voltage follows the input signal. With such an arrangement, if the variable resistance 5 is adjusted to V2=VR+V1, the output voltage such as transient voltage on the positive side is clamped to zero V and the pointer of the meter is deflected in the opposite direction to prevent damage to the meter.

Title: Judgment method for nitrogen concentration in gate oxide film
Inventor: IWATA YASUSHI
IPC: H01L29/78
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To estimate nitrogen concentration on the basis of a simply calculated reoxidated film thickness rate by a method wherein the nitrogen concentration is judged on the basis of the deposition speed of a thermal oxide film. SOLUTION: A thermal oxide film 2 is formed on a semiconductor substrate 1 by a CVD method. After that, the thermal oxide film 2 is heated for a short time in a nitrous oxide atmosphere, and an oxynitride film 3 is formed. After that, when the oxynitride film is heated for a short time in an oxygen atmosphere, the oxynitride film is reoxigized, and a reoxidation film 4 is formed. A reoxidation film thickness rate is found on the basis of a film thickness L1 after the oxynitride film is formed by oxidizing N2O and on the basis of a film thickness L2 after a reoxidation treatment performed thereafter. A thermal oxide film thickness which is found by an optical film-thickness measuring device is 40 Å as a target film thickness. A linear relationship is established between the concentration of nitrogen in a gate oxide film and a reoxidation rate.  When the reoxidation rate with reference to the oxynitride film by a treatment under an oxynitriding condition is calculated, the concentration of the nitrogen can be estimated. By using this characteristic, the concentration of the nitrogen in the gate oxide film is judged.
