Title: Manufacturing method of semiconductor element
Inventor: YOSHIMARU MASAKI
IPC: H01L27/108
Filed: 1991-12-12
Abstract: PURPOSE:To ensure the large capacitor capacity by a method wherein, after the formation of the lower electrode of a capacitor part on a semiconductor substrate, the surface of the lower electrode is nitrified to form a nitride film for the formation of a dielectric film. CONSTITUTION:For example, a capacitor lower electrode 6 is formed of polysilicon (Si layer) 6 on a semiconductor substrate and then the substrate of the Si layer is nitrified to form an Si3N4 film 7 as a nitride film. Next a Ta2O5 8 as a high dielectric film is formed on the Si3N4 film 7 formed on the surface of the lower electrode 6. At this time, due to the Si3N4 7 formed beneath the Ta2O5 film 8 a silicon oxide film can not be formed on the lower electrode 6 during the forming step of the Ta2O5 film 8 and even if it is ozone-annealed. Through these procedures, the large capacitor capacity can be ensured.

Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To enlarge a range where operation frequency of a switching means becomes higher than a resonance frequency to a low pass side and to prevent the occurrence of through current when AC power voltage suddenly drops or a load suddenly increases, by using a current resonance capacitor whose capacity increases when the operation frequency drops. SOLUTION: In a current resonance power circuit where a primary wire L21 of a switching transformer 24 and a current resonance capacitor C21 are resonated with switching means 21 and 22 and high frequency output is obtained in the secondary wire L22 of the switching transformer 24, the current resonance capacitor C21 whose capacity increases when the operation frequency drops is used. When output voltage E2 drops by the increase of the load or the voltage drop of a AC power source 11, a resonance point is lowered and the area of a normal operation is enlarged on the low pass side at the time of executing an operation for dropping the operation frequency, raising output voltage E2 and returning voltage to an original value by a control circuit 27. Thus, the occurrence of through current is prevented and the destruction of the switching means is prevented.

Title: Detecting circuit for video tape recorder signal
Inventor: MITSUSHIERU ANBEERU
IPC: H04N5/05
Filed: 1988-12-28
Abstract: PURPOSE: To improve the follow-up performance of a PLL and prevent a vertical distorted screen from appearing by detecting low-frequency vibration characteristic of the tape recorder signal and automatically switching the time constant of the PLL in a TV image receiver to a small value. CONSTITUTION: To confirm that the VTR signal is at a terminal 10, a phase comparison 22 between the output signal of a synchronous separating circuit 11 and the output signal of the PLL 12 is made. A comparator 22 has a substantially shorter time constant than the time constant of the PLL 12 so as to detect low-frequency variation of a synchronizing signal, and this time constant is determined by a capacitor C2 which is fed by a current source 12. The output of the comparator 22 is sent to a threshold comparator 24, which supplies a low-level signal only when the output signal of the comparator 22 is within a specific range and supplies a high-level signal only when a low-frequency noise is present unless the output signal is within the specific range, thereby controlling the operation of switches 20 and 26.

Title: Crystal film thickness monitor
Inventor: SHIMODA YOSHIO
IPC: G01B17/02
Filed: 1988-12-27
Abstract: PURPOSE:To monitor an accurate vapor-deposition film thickness even under high temperature environment by forming plural crystal vibrators on a crystal raw plate subject to sweeping processing and measuring a frequency difference. CONSTITUTION:Crystal vibrators 3, 4 are formed on a crystal raw plate 1 subject to sweeping processing while being applied with a high voltage at a high temperature and operated stably even at a temperature of 500 deg.C or over with electrodes 2A, 2B, 2C. A holder 5 has an opening 9 facing the vibrator 4 and the vapor-depositted material from the vapor-deposition source is deposited only to the vibrator 4 and the frequency f2 of a drive circuit 7 varies with the depositted quantity. On the other hand, since no material is deposited to the vibrator 3, the frequency f1 of a drive circuit 6 is unchanged and the vapor- deposited quantity is measured depending on an output frequency f1-f2 of a mixer 8. Thus, the crystal film thickness monitor operated stably even at the high temperature of 500 deg.C or over and able to measure the film thickness accurately is obtained.
