High registration particles-transferring system
Disclosed herein are implementations of a particles-transferring system, particle transferring unit, and method of transferring particles in a pattern. In one implementation, a particles-transferring system includes a first substrate including a first surface to support particles in a pattern, particle transferring unit including an outer surface to be offset from the first surface by a first gap, and second substrate including a second surface to be offset from the outer surface by a second gap. The particle transferring unit removes the particles from the first surface in response to the particles being within the first gap, secures the particles in the pattern to the outer surface, and transports the particles in the pattern. The second substrate removes the particles in the pattern from the particle transferring unit in response to the particles being within the second gap. The particles are to be secured in the pattern to the second surface.
TRANSFER VEHICLE SYSTEM
A transfer vehicle system in which transfer vehicles travel on a track includes a measurement portion in a portion of a path continuing to the track to measure a measurement target portion included in the transfer vehicle on the path, an identifier to identify the transfer vehicle for which the measurement target portion has been measured by the measurement portion, a storage to store a measurement result measured by the measurement portion and an identification result identified by the identifier in association with each other, and a display to provide notification of information concerning a state of the measurement target portion determined based on the measurement result and a reference value.
ELECTRONIC COMPONENT TEST HANDLER HAVING FLYING SCAN FUNCTION
The present invention relates to an electronic component test handler comprising: a hand configured to pick up and transfer a plurality of devices; and a scanner configured to scan a region of a movement path of a device picked up by the hand at a predetermined angle. The electronic component test handler having a flying scan function according to the present invention is capable of scanning during a transfer process without a change in position after picking up a device, and thus, operations and time required for the scanning may be reduced, thereby improving efficiency.
Wafer forming apparatus
A wafer forming apparatus includes a conveying tray having an ingot accommodating section that accommodates a semiconductor ingot and a wafer accommodating section that accommodates a wafer formed from the semiconductor ingot, a belt conveyor unit that conveys the conveying tray to each processing apparatus, a cassette rack on which cassettes accommodating the wafers are placed correspondingly to the conveying trays, and a transferring unit that transfers the wafer from the wafer accommodating section of the conveying tray to the cassette placed on the cassette rack. The conveying tray is provided with an identification mark. The cassette rack or the cassette corresponding to the conveying tray is provided with the same identification mark as the identification mark provided on the conveying tray.
DEVICE FOR RECOGNIZING WAFER IDENTIFICATION NUMBER WITH AUTOMATICALLY TURNING ON AND OFF RECOGNIZING FUNCTION
A device for recognizing wafer identification number with automatically turning on and off recognizing function comprises a base, a support frame, a light source, a plurality of image capturing units, an image recognition unit and a control unit. The base comprises a wafer boat placing portion and a first switch disposed on the wafer boat placing portion. The light source and the image capturing units are disposed on the support frame. The control unit is electrically connected to the first switch, the light source, the image capturing units and the image recognition unit. As such, the device for recognizing wafer identification number with automatically turning on and off recognizing function can automatically turn on and off the light source, the image capturing units, and the image recognition unit, therefore the operation is very easy and convenience.
TRAVELING VEHICLE AND TRAVELING VEHICLE SYSTEM
A traveling vehicle travels along a traveling path and includes a main body, a traveler to allow a main body to travel along the traveling path, an LED array provided at the main body to switch a display manner according to a state of the traveling vehicle, an imager to capture an image of the LED array at a traveling vehicle located ahead of the traveling vehicle, and a controller configured or programmed to acquire a state of the traveling vehicle ahead based on the display manner captured by the imager, and to control the traveler of the traveling vehicle based on the acquired state.
Treatment condition setting method, storage medium, and substrate treatment system
This method includes a step of imaging, by an imaging apparatus in a substrate treatment system, a reference substrate which is a reference for condition setting and acquiring a captured image of the reference substrate; and a step of imaging, by the imaging apparatus, a treated substrate on which the predetermined treatment has been performed under a current treatment condition and acquiring a captured image of the treated substrate. A deviation amount in color information between the captured image of the treated substrate and the captured image of the reference substrate is calculated. A correction amount of the treatment condition is calculated based on a correlation model acquired in advance and on the deviation amount in the color information. Also included is a step of setting the treatment condition based on the correction amount and performing the treatment on a target substrate based on the set treatment condition.
WAFER FRAME SORTER AND STOCKER
A wafer sorting and stoking system provides automated storage and retrieval of wafer frames carrying semiconductor wafers. A wafer frame cassette is received at a transfer port from a transfer system. A robot arm retrieves the wafer frames from the cassette and stores each wafer frame in a respective storage slot in one of a plurality of storage towers. The storage location of each wafer frame is recorded. Each wafer frame can be selectively retrieved and loaded into a wafer frame cassette by the robot arm for further processing.
Wafer manufacturing system
A wafer manufacturing system includes a wafer manufacturing device provided with a sensor; a host PC that is connected to the wafer manufacturing device via a data communication line; a logic controller that samples and stores an analog output signal of the sensor; and a relay PC that extracts tracking information transmitted on the data communication line for a wafer or a single crystal that is being processed by the wafer manufacturing device and sends the tracking information to the logic controller, and the logic controller stores a digital value of the analog output signal of the sensor in association with the tracking information that is sent from the relay PC.
Front surface and back surface orientation detection of transparent substrate
A system includes a substrate support on which to receive a transparent substrate, a non-contact sensor adapted to detect and image a dot pattern etched on a front surface of the transparent substrate, and a processing device attached to the non-contact sensor. The processing device may determine, using imaging data from the non-contact sensor, an orientation of a right-angled edge of the dot pattern. The processing device may determine, based on the orientation of the right-angled edge, whether a front surface of the transparent substrate is facing up or facing down. The processing device may also direct a robot to transfer the transparent substrate to a processing chamber dependent on whether the front surface of the transparent substrate is facing up or facing down.
