Conveyance equipment 10 for conveying a plate-like member includes plural items of liquid discharging equipment that hold the member by discharging liquid to generate a negative pressure between the liquid discharging equipment and the member. Each of the plural items of liquid discharging equipment includes a columnar main body, a flat end face formed at the main body, which faces the member, a concave part formed at the end face, and one or more liquid passages that discharge liquid into the concave part at a peripheral edge of the concave part. The one or more liquid passages are arranged so that a direction in which a liquid flows out of the concave part along the end face and a direction from a center of gravity of the member toward a position of the member, opposite the liquid discharging equipment, form an angle smaller than or equal to 90 degrees.

A transfer device is provided for substrate transfer along a transport direction and for change between a first transport path and a second transport path extending along the transport direction. The first transport path is displaced with respect to the second transport path in a switch direction perpendicular to the transport direction. The transfer device includes a first substrate support assembly defining a first track to support a substrate or substrate carrier in a chamber. The transfer device further includes a second substrate support assembly defining a second track to support a substrate or substrate carrier in the chamber. The first substrate support assembly and the second substrate support assembly are moveable relative to each other at least in the switch direction.

The present invention relates to an end effector device 1 attached to a tip end portion of a robot arm, and the end effector device 1 includes a plurality of support units 3 provided on a blade 10. Each of the support units 3 includes: a plurality of nail pieces 30 configured to support peripheral portions of a plurality of semiconductor wafers 9 such that the semiconductor wafers 9 are parallel to one another and spaced apart from one another; and a pitch changing mechanism 4 configured to change upper-lower intervals of the nail pieces 30. The pitch changing mechanism 4 includes: a coil spring 40 configured to support the plurality of nail pieces 30 such that the plurality of nail pieces 30 are spaced apart from one another in an upper-lower direction and elastically deform in the upper-lower direction; and an operating mechanism 5 configured to cause the coil spring 40 to elastically deform in the upper-lower direction. The operating mechanism 5 includes a piston pin 50 fitted in the coil spring 40 to move up and down.
摘要:
A substrate stopped at a first position is transferred toward a second position and is stopped at the second position in an accurate and stable manner. An intermediate position arrival time AT is measured while the substrate is being transferred from a substrate stop position toward a mounting work position, and a transfer status of the substrate (whether or not an unexpected factor has occurred) is assessed based on the intermediate position arrival time AT. Before the substrate reaches the second position, a deceleration pattern is controlled by altering a deceleration start timing T14 and the deceleration b in accordance with the intermediate position arrival time AT, thereby accurately stopping and positioning the substrate at the mounting work position. In this manner, under feed-forward control, the substrate can be stably transferred to the mounting work position.

An improved, lower cost method of processing substrates, such as to create solar cells is disclosed. In addition, a modified substrate carrier is disclosed. The carriers typically used to carry the substrates are modified so as to serve as shadow masks for a patterned implant. In some embodiments, various patterns cart be created using the carriers such that different process steps can be performed on the substrate by changing the carrier or the position with the carrier, in addition, since the alignment of the substrate to the carrier is critical, the carrier may contain alignment features to insure that the substrate is positioned properly on the carrier, in some embodiments, gravity is used to held the substrate on the carrier, and therefore, the ions are directed so that the ion beam travels upward toward the bottom side of the carrier.

A system and method are used to levitate and translate a stage within a chamber using a motor assembly coupled to a balance mass assembly. The balance mass assembly is positioned adjacent the chamber. The motor assembly includes a stator and a coil. One of the stator and the coil are coupled to the stage on a first side of a wall of the chamber. The other of the stator and the coil are coupled to the balance mass assembly on a second side of the wall of the chamber. A magnetic assembly coupled to the stage allows the stage to levitate within the chamber. Once levitated, the stage is translated based on the interaction of the magnets and an energized coil.

摘要:
Disclosed is an installation which is characterized by the fact that it comprises several independent and aligned modules (M). Each of said modules (M) is provided with a vacuum treatment chamber (C) and a transfer chamber (B) with means for transferring a substrate within one of the different chambers or from one chamber to another, the second chamber being located downstream or upstream from, directly next to, or separated by at least one module from the first chamber, such that a substrate can be transferred into one chamber in order to undergo a treatment while another substrate is placed in a different chamber for a specific treatment.
