  • Publication number: 20120125376
    Abstract: A wet processing apparatus holds on a stage a substrate to be processed and carries out a wet treatment by rotating the stage. The substrate is held by the stage, with the center of the substrate being offset from the rotation center of the stage, using a Bernoulli chuck which causes an inert gas to flow to a back surface of the substrate, so that the substrate is eccentrically rotated along with the rotation of the stage. A first gas supply passage which is used for the Bernoulli chuck is provided at a rotation shaft portion in the stage and the stage is also provided with second gas supply passages which communicate with the first gas supply passage to thereby introduce the inert gas to the back surface of the substrate. The second gas supply passages are axisymmetric with respect to a central axis of the substrate.

  • Patent number: 8183165
    Abstract: According to the present invention,when a nitridation process by plasma generated by a microwave is applied to a substrate with an oxide film having been formed thereon to from an oxynitride film, the microwave is intermittently supplied. By the intermittent supply of the microwave, ion bombardment is reduced in accordance with a decrease in electron temperature, and a diffusion velocity of nitride species in the oxide film lowers, which as a result makes it possible to prevent nitrogen from concentrating in a substrate-side interface of an oxynitride film to increase the nitrogen concentration therein. Consequently,it is possible to improve quality of the oxynitride film, resulting in a reduced leadage current, an improved operating speed, and improved NBTI resistance.

  • Patent number: 8184461
    Abstract: A first circuit generates a first sequence of square wave voltages having a voltage level that changes to a positive side relative to a first reference potential, which is a potential on a negative-electrode side of a direct current power source, from a direct current voltage. A second circuit generates a second sequence of square wave voltages having a voltage level lower than the voltage level of the first sequence of square wave voltages on the positive side that changes to a negative side relative to a second reference potential. The second chopper circuit further generates a third sequence of square wave voltages having a voltage level that changes to the positive and negative side in turns in the manner of sinusoidal wave relative to the first reference potential by summing the first sequence of square wave voltages and the second sequence of square wave voltages. A third circuit outputs the third sequence of square wave voltages as a charge/discharge output.

  • Patent number: 8181769
    Abstract: A workpiece transfer mechanism 76 transfers workpieces W to a workpiece boat 40 having ringlike tables 86. The transfer mechanism 76 includes a fork main body 78 being movable forward and rearward with the workpiece W placed thereon; stopper members 94 provided at the end portion of the fork main body 78; clamp means 96 provided on the proximal end side of the fork main body 78 and having a pressing portion 102 coming into contact with the circumferential edge of the workpiece W and pressing the workpiece W toward the stopper member 94 for clamping; and fork elevating means 80 for lifting and lowering the fork main body 78. When the workpieces W are transferred to a workpiece boat 40, the pressing portion 102 of the clamp means 96 is controlled so as not to be inserted into a gap between tables 86. Thus, although the pitch between the tables 86 is small, the pressing portion 102 of the clamp means 96 does not interfere with the workpiece boat 40.

  • Patent number: 8182014
    Abstract: With a vehicle seat arranging structure, a second-row passenger-side seat may be placed in a rearward slide position by sliding the second-row passenger-side seat toward the rear of a vehicle by 150 millimeters so that the second-row passenger-side seat is closer to the rear of the vehicle than the second-row driver-side seat. In addition, each of the second-row driver-side seat and the second-row passenger-side seat may be placed in an obliquely-inward frontward-oriented position by swiveling each of the second-row driver-side seat and the second-row passenger-side seat from the frontward-oriented position 10 degrees inward in the vehicle-width direction. In this way, the sense of distance between the occupants seated in the second-row driver-side seat and the second-row passenger-side seat is reduced. As a result, it is possible to promote communication between these occupants (to make it easier for these occupants to communicate with each other).

  • Patent number: 8181660
    Abstract: A treatment liquid permeation unit comprises: at least one vibration unit; and a vibration transmission unit for transmitting a vibration from the vibration unit. The vibration transmission unit is positioned between an adhesive with which a wafer is combined to a supporting plate or an adhesive adhered to a surface of the wafer and the vibration unit. A vibration from the vibration unit is transmitted via the vibration transmission unit. This promotes the treatment liquid for dissolving the adhesive to permeate the adhesive to which the treatment liquid is supplied. Therefore, the treatment liquid can more uniformly permeate the adhesive in a shorter time. This allows the treatment liquid for dissolving the adhesive to permeate the adhesive with which the wafer is combined to the supporting plate or to permeate the adhesive adhered to the surface of the wafer in a shorter time.
