  • Publication number: 20130199727
    Abstract: Provided is a capacitively coupled plasma processing apparatus which improves a controllability of the RF bias function and reliably prevents unwanted resonance from being generated on a RF transmission line between a counter electrode and ground potential to enhance reliability of the plasma process. In the capacitive coupled type plasma processing apparatus, three kinds of RF powers from a first, second and third RF power supplies (35, 36, 38) are superimposed and applied to susceptor (lower electrode) (16). In such a three-frequency superimposing and applying application scheme, the frequency-impedance characteristic around upper electrode (48) is considered to prevent a serial resonance from occurring on an RF transmission line around upper electrode (48) in consideration of all the low order frequencies of the IMD relevant to and affecting the plasma process.

  • Publication number: 20130202388
    Abstract: There is provided a technique which can prevent poor processing of successive substrates in the event of a failure of a module or a transport mechanism for transporting a substrate between modules. A substrate processing apparatus includes: a plurality of modules from which a substrate holder of a substrate transport mechanism receives a substrate; a sensor section for detecting a displacement of the holding position of a substrate, held by the substrate holder, from a reference position preset in the substrate holder; and a storage section for storing the displacement, detected when the substrate holder receives a substrate from each of the modules, in a chronological manner for each module. A failure of one of the modules or the substrate transport mechanism is estimated based on the chronological data on the displacement for each module, stored in the storage section. This enables an early detection of a failure or abnormality.

  • Publication number: 20130204425
    Abstract: When a substrate is transferred by a holding arm to a multiple tier wafer boat, contact between the holding arm and the substrate is prevented. When the wafer boat is not subjected to a thermal effect, a normal height position of a ring member is obtained by relatively elevating and lowering a transfer base member with respect to the wafer boat. Before a wafer, which is not yet thermally processed, is transferred to the wafer boat, a height position of the corresponding ring member is obtained. By comparing a difference between the normal height position of the ring member and the height position of the ring member before the wafer is transported, with a threshold value, whether to transfer the wafer by the wafer transfer mechanism to the wafer boat can be judged.
