    摘要: An apparatus for holding an object to be processed, according to this invention is mounted in a plasma processing apparatus and includes a convex-shaped holder main body, first dielectric film, and second dielectric film. The holder main body has a holding portion which holds an object to be processed placed on it and a flange formed on the peripheral portion of the holding portion to fit with a focus ring. The first dielectric film attracts the object to be processed placed on the holding portion to the holder main body by a Coulomb force. The second dielectric film attracts the focus ring fitted on the flange to the holder main body by an attracting force larger than that of the first dielectric film using a Johnson-Rahbek force. The electrostatic attracting force of the focus ring for the holder main body is increased, so that the cooling effect is increased. A change in plasma processing characteristics over time in the vicinity of the focus ring can be eliminated, and the entire surface of the object to be processed can be processed uniformly.

    摘要: A substrate processing method uses a substrate processing apparatus including a chamber for accommodating a substrate, a lower electrode to mount the substrate, a first RF power applying unit for applying an RF power for plasma generation into the chamber, and a second RF power applying unit for applying an RF power for bias to the lower electrode. The RF power for plasma generation is controlled to be intermittently changed by changing an output of the first RF power applying unit at a predetermined timing. If no plasma state or an afterglow state exists in the chamber by a control of the first RF power applying unit, an output of the second RF power applying unit is controlled to be in an OFF state or decreased below an output of the second RF power applying unit when the output of the first RF power applying unit is a set output.

    摘要: The present invention provides an upper electrode used in an etching apparatus and the etching apparatus including the upper electrode, both of which can properly reduce intensity of electric field of plasma around a central portion of a substrate to be processed, thus enhancing in-plane uniformity of a plasma process. In this apparatus, a recess, serving as a space for allowing a dielectric to be injected therein, is provided around a central portion of the upper electrode. A dielectric supply passage configured for supplying the dielectric into the space and a dielectric discharge passage configured for discharging the dielectric from the space are connected with the space, respectively. With such configuration, the dielectric can be controllably supplied into the recess, such that in-plane distribution of the intensity of the electric field can be uniformed, corresponding to in-plane distribution of the intensity of the electric field of the plasma generated under various process conditions, such as a kind of each wafer that will be etched, each processing gas that will be used, and the like.

    摘要: A transfer apparatus transfers an object to be transferred onto a case. The transfer apparatus includes a transfer arm, an arm shaft, a plurality of electromagnets, and a control unit. The transfer arm has a pick unit on a front end thereof and extends and retracts in a horizontal direction. The object to be transferred is held on the pick unit. The arm shaft supports the transfer arm. The plurality of electromagnets apply an force in upward direction to the transfer arm by generating a magnetic field in the case. The control unit controls the plurality of electromagnets in such a manner that when the transfer arm extends and retracts in the horizontal direction, the force in upward direction applied to the transfer arm increases as a length from the arm shaft to the front end of the transfer arm increases.
