摘要:
A silicon compound gas, an oxidizing gas, and a rare gas are supplied into a chamber (2) of a plasma processing apparatus (1). A microwave is supplied into the chamber (2), and a silicon oxide film is formed on a target substrate with plasma generated by the microwave. A partial pressure ratio of the rare gas is 10% or more of a total gas pressure of the silicon compound gas, the oxidizing gas, and the rare gas, and an effective flow ratio of the silicon compound gas and the oxidizing gas (oxidizing gas/silicon compound gas) is not less than 3 but not more than 11.
摘要:
Word line driver circuitry for selectively charging and discharging one or more word lines is provided. The driver circuitry uses a dual transistor topology, where a first transistor is driven by a signal, DOUT, and a second transistor is driven by a time-delayed complement of the DOUT, DOUT_BAR. The time delay prevents DOUT_BAR from changing its state immediately after DOUT changes state. As result, both the first and second transistors are turned ON at the same time for a predetermined of time. It is during this time that the voltage on the word line is rapidly driven to a LOW voltage. When the second transistor turns OFF, high impedance circuitry limits the flow of leakage current. This minimizes leakage current when the word line is OFF and when short circuit conditions are present between two or more word lines or between a word line and a bit line.

摘要:
A dielectric TEM resonator, whose resonant frequency is adjustable in both directions after being incorporated in a circuit, is disclosed. A first dielectric TEM resonator comprises a metal member disposed near an open end of a resonator body and coupled to an inner or outer conductor of the resonator body. The resonant frequency is adjusted by adjusting a distance between the open end and the metal member. A dielectric material of a second dielectric TEM resonator is partially exposed, and a dielectric board for mounting the resonator body is also exposed in a corresponding part to the exposed part of the dielectric material. The exposed part of the dielectric board is partially covered with a metal plate. The resonant frequency is adjusted by adjusting the covered area.
