摘要:
A method for cleaning a microwave plasma processing apparatus is disclosed wherein a cleaning gas is introduced and then excited with microwave plasma (step 3). By applying high-frequency power to a substrate supporting stage by which a substrate to be processed is supported (step 4), the etching rate is improved, thereby shortening the cleaning time.

The performance of a plasma processing apparatus which is disassembled, transferred, and reassembled is evaluated. The plasma processing apparatus has a plasma processing chamber having an electrode for exciting a plasma, a radiofrequency generator connected to the electrode, and an impedance matching circuit for performing the impedance matching between the plasma processing chamber and the radiofrequency generator. The performance of the apparatus is evaluated whether or not three times the first series resonant frequency of the plasma processing chamber is larger than the power frequency supplied to the plasma processing chamber.

摘要:
A pressure sensor, a pressure control apparatus, and a flow rate control apparatus are provided to automatically correct temperature drift of the pressure sensor and accurately detect pressure despite changes in temperature. An embodiment includes an upstream side pressure sensor between an orifice and a control valve, to control flow rate through the orifice by a regulating control valve, while calculating the flow from the upstream side pressure. With a temperature sensor, a memory means, and a temperature drift correcting means which calculates drift of the upstream side pressure sensor from data in the memory means when the temperature of the fluid changes and offsets the output drift of the upstream side pressure sensor with the calculated amount of the output drift, temperature drift of the pressure sensor is automatically corrected, enabling accurate control of flow rate.
摘要:
The present invention provides a valve which makes it possible to reduce the diameter of the vacuum exhaustion pipings for making the facility for the vacuum exhaustion system small, as a result lowering the costs, and making the vacuum exhaustion time short, and also which can prevent the corrosions, cloggings, and seal leakages inside the piping system caused by the accumulation of substances produced by the decomposition of the gas. Specifically, the aluminum passivation is applied on the piping parts, i.e. the valve and others, used in the vacuum exhaustion system to inhibit the gas decomposition caused by the temperature rise at the time of the baking so that components for the reduction in the diameter size in the vacuum exhaustion system are provided. The corrosions, cloggings and seat leakages caused by the gas decomposition are prevented.

There is provided a small-type semiconductor integrated circuit whose circuit area is small and whose wiring length is short. The semiconductor integrated circuit is constructed in a multi-layer structure and is provided with a first semiconductor layer, a first semiconductor layer transistor formed in the first semiconductor layer, a wiring layer which is deposited on the first semiconductor layer and in which metal wires are formed, a second semiconductor layer deposited on the wiring layer and a second semiconductor layer transistor formed in the second semiconductor layer.

摘要:
A pressure-type flow rate control apparatus controls the flow rate of fluid passing through an orifice to a target flow rate. The flow rate of a compressible fluid under non-critical conditions (sub-sonic) passing through the orifice is calculated by: Qc=KP2m(P1−P2)n so that the flow rate can be controlled to the target flow rate with high precision and speed. Also provided is an improved pressure-type flow rate control apparatus in which a pressure ratio P2/P1=r, obtained from an upstream pressure P1 and a downstream pressure P2 is constantly compared with a critical value r, and under critical conditions (r≦rc), the flow rate is calculated by: Qc=KP1. Under non-critical conditions (r>rc), the flow rate is calculated by Qc=KP2m(P1−P2)n.
