  • Patent number: 9280064
    Abstract: A method of projecting a pattern from a patterning device onto a substrate using a projection system, the method including using an optical phase adjustment apparatus in the projection system to apply a phase modification to radiation which has been diffracted from an assist feature of the pattern, the phase modification acting to reduce the size of an assist feature image exposed in resist on the substrate or prevent printing of the assist feature image in the resist on the substrate, while maintaining a contribution of the assist feature image to an image enhancement of a functional feature of the pattern.

  • Patent number: 9229313
    Abstract: An exposure apparatus includes an atmosphere maintaining unit which maintains an exposure chamber in an air atmosphere, a gas supply unit which supplies air or a mixed gas containing air and an inert gas to a local space, between a final surface of a projection optical system and a substrate, a detector which detects an alignment mark and a reference mark formed on the substrate stage, and a controller. The controller controls the gas supply unit not to supply the mixed gas to the local space when the detector detects the reference mark, and controls the gas supply unit to supply the mixed gas to the local space when an instruction to detect the alignment mark upon setting the local space in a mixed gas atmosphere, and expose the substrate based on the detection results of the reference mark and the alignment mark is issued from the recipe.

  • Patent number: 9164400
    Abstract: One pair each of a Y linear motor (a total of four) on the +X side and the ?X side that drive a reticle stage include one pair each of a stator section (a total of four) and three each of a mover section (a total of six) on the +X side and the ?X side. In this case, the three each of the mover sections on the +X side and the ?X side configure one each of a mover. The mover section located in the center in the Z-axis direction of each of the movers is used in common by each pair of the Y linear motors. Therefore, the weight of the mover section (reticle stage) of the reticle stage device is reduced, which allows a higher acceleration. Further, the mover section located in the center in the Z-axis direction of each of the movers coincides with a neutral plane of the reticle stage.

  • Patent number: 9123760
    Abstract: A processing apparatus of the present invention processes for a wafer. The processing apparatus includes an XY stage which includes a wafer chuck which holds the wafer and an elevating device which rises relative to the wafer chuck to hold the wafer, and a wafer conveying robot hand which conveys the wafer from the XY stage at a wafer transfer position. The XY stage moves to change a direction at an angle between degree and degree via the wafer transfer position in a state where the elevating device rises relative to the wafer chuck. The wafer conveying robot hand has a shape which does not interfere with the XY stage which moves to change the direction at the angle when the wafer conveying hand is positioned at the wafer transfer position.

  • Patent number: 9086495
    Abstract: A two step method of scanning objects to gain information about material content comprises the steps of providing a radiation source and a radiation detector system spaced therefrom to define a scanning zone therebetween. In a first scanning step, an object is moved relative to the source and detector system, intensity information about radiation incident at the detector system after interaction with the object as it passes through the scanning zone is collected, variation of intensity as the object moves through the scanning zone is used to identify anomalous structures and/or absence of homogeneity in the object. In a second, subsequent scanning step an object is located in fixed position in the scanning zone and collecting intensity information collected, analysed against a suitable functional relationship relating transmitted to incident intensity, and the results compared with a library of suitable data to provide an indication of material content.

  • Patent number: 9057680
    Abstract: Provided is a diagnostic method and system capable of applying tomography to industrial long cylindrical process systems, such as a pipe line, which are difficult to diagnose using existing medical or industrial computed tomography (CT) scanners. Existing industrial X-ray CT scanners cannot be used for such a pipe that is attached to the process system and thus cannot be placed on the turntable, and existing image diagnostic apparatuses of a fan beam type, a collimated beam type, etc. having a stereotyped structure are next to impossible to move and use for undetachable process systems and their peripheral devices. To solve these problems, there is provided a gamma-ray tomography scanning system that is capable of being directly attached to a pipe in operation and measuring a cross section of the pipe.

  • Patent number: 9055874
    Abstract: A motion tracker including a head band and laser devices that direct laser beams having non-concentric axes to a charge coupled device is used to determine movement of a patient during a CT scan. When the patient is motionless, the laser devices each direct a laser beam along a line, and the laser beams contact the charge coupled device at a contact location. If the patient moves, the laser devices, and therefore the contact locations, move. The charge coupled device detects the movement of the contact locations to determine the movement of the patient. A computer adjusts the x-ray image taken at the time of the movement to accommodate for this movement.

  • Patent number: 9036785
    Abstract: In a high-voltage apparatus according to this invention, a predetermined voltage is applied to a rotating anode after waiting until the number of rotations increases to such an extent that the rotating anode is not damaged. That is, X-rays of desired intensity are already outputted from a point of time when the voltage is applied to the rotating anode. Therefore, diagnosis can be performed immediately after the voltage is applied to the rotating anode. That is, unlike the prior art, there is no need to wait until X-ray intensity becomes suitable for diagnosis after X-ray emission is started, and there is no need to irradiate the patient with unnecessary X-rays. Therefore, the patient can be inhibited from being irradiated with excessive X-rays (with an improvement made in a response from when the operator gives instructions for starting fluoroscopy until emission of X-rays suitable for diagnosis).
