Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To easily manufacture a highly integrated highly reliable semiconductor device with a high yield by reducing the thickness of a ferroelectric film after the film is formed thicker than prescribed and restoring the deteriorated surface layer of the ferroelectric film. SOLUTION: After a TiN film 12 having a thickness of 50nm is formed on a silicon substrate 11 as a diffusion preventing layer, a Pt film having a thickness of 200nm is formed on the film 12 as a base electrode 12 and a lead zirconate titanate film having a thickness of 150nm is formed on the film 13 as a ferroelectric film 14. Then the thickness of the film 14 is reduced to 50nm by etching the entire surface of the film 14 by reactive dry etching using a mixed gas of CF4 and Ar. After the thickness of the film 14 is reduced the deteriorated surface layer of the film 14 is restored by performing heat treatment at 300-500 deg.C. Therefore, various kinds of semiconductor memories, such as the dynamic random access memory, etc., can be manufactured ideally, because a sufficiently thin ferroelectric film having excellent characteristics can be formed with high reproducibility.

Title: Inverter type x-ray high-voltage device
Inventor: OHARA KOICHI
IPC: H05G1/20
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To prevent lowering of a tube voltage due to excessiveness or shortage of an input voltage or redundant heating of an inverter circuit by adding a correction quantity to an input voltage set value calculated according to radiation conditions of a desired X-ray and calculating an input voltage target signal. SOLUTION: Correction calculation means 11 increases an input voltage when a tube voltage control quantity outputted by tube voltage feedback controlling means 10 is greater than a given value (for example, 98% or more) and decreases the input voltage when it is smaller than a given value (for 90% or less), a correction quantity of this input voltage is calculated, and a correction quantity of an input voltage target value inputted to input voltage feedback controlling means 9 is calculated. If the input voltage is insufficient and cannot be controlled to a given tube voltage by an inverter circuit, the input voltage is increased, and when the input voltage is increased the input voltage is decreased. Thereby, even if dispersion in adjustment or device occurs, the input voltage of the inverter circuit is properly maintained, and redundant heating is prevented.

Filed: 1990-11-29
Abstract: PURPOSE:To evade the deterioration of the control speed of a control device despite the increase of the number of switches and control subjects by providing a change detection means which detects the OFF-ON and ON-OFF states of the switches and a control means which gives the different numerical values to a D/A converter when the state change of the switch is detected. CONSTITUTION:A rise edge detection circuit 10 is provided to detect the OFF-ON change of a switch 1 together with a fall edge detection circuit 11 which detects the ON-OFF change of the switch 1, and the delay circuits 12 - 14. The signal is outputted only once when the switch 1 changes to the ON state from the OFF state, and the signals are repetitively outputted in the fixed frequency when the switch 1 changes to the OFF state from the ON state respectively. A microprocessor circuit 3 checks the state of the switch 1 to continuously change the numerical value given to a D/A converter 9 when the ON state of the switch 1 is confirmed. Meanwhile the present numerical value of the converter 9 is kept as it is when the OFF state of the switch 1 is confirmed. Thus the state of the switch 1 is limited only when the state of the switch 1 is changed. As a result, the load is reduced and the control speed is never deteriorated despite the increase of the number of switches and control subjects.
