摘要:
In a carrier system, a chuck unit (153) is used to hold a placed wafer (W) from above, and vertical-motion pins (140) use suction to hold the wafer (W) from below. Then, chuck unit (153) and vertical-motion pins (140) are subsequently lowered until a bottom surface of the wafer comes into contact with a wafer table (WTB). During the lowering, the holding force exerted by chuck unit (153) and the arrangement of chuck members (124) are optimally adjusted such that, as a result of the restraint of wafer (W) by chuck unit (153) and vertical-motion pins (140), localized surplus-restraint is imparted to wafer (W), and warping does not occur.

The end effector device (1) includes a hand (3) having a storing space, and a plurality of holding portions (4A, 4B) provided to the hand (3) and configured to respectively peripheral portions of each plate member. Each holding portion (4A, 4B) includes a plurality of receiving portions (42) which respectively receive a plurality of plate members keeping vertical pitches among them, and a pitch changing mechanism (7) configured to change intervals by vertically moving the plurality of receiving portions (42) respectively. A plurality of linearly moving portions (41A) configured to respectively move linearly integrally with the plurality of receiving portions (42) are provided to the hand (3) being exposed outside of the hand (3), and a plurality of drive portions configured to drive the plurality of linearly moving portions (41A) of the pitch changing mechanism (7) are stored in the storing space of the hand (3).

In this specification, a chip supplying apparatus which supplies a chip to a mounting machine which mounts the chip on a substrate is disclosed. The chip supplying apparatus is provided with a wafer table which holds a wafer sheet at a position where an operation head of the mounting machine can receive the chip. In the chip supplying apparatus, the wafer table is provided with a frame, a stopper which is fixed to the center of a front portion of the frame and abuts against a front end of the wafer sheet, and a pair of clamp mechanisms which is supported by the frame and which clamps both side ends of the wafer sheet. In the chip supplying apparatus, a position of the pair of clamp mechanisms in a right-and-left direction with respect to the frame can be changed in multiple steps.

A telepresence robot may include a drive system, a control system, an imaging system, and a mapping module. The mapping module may access a plan view map of an area and tags associated with the area. In various embodiments, each tag may include tag coordinates and tag information, which may include a tag annotation. A tag identification system may identify tags within a predetermined range of the current position and the control system may execute an action based on an identified tag whose tag information comprises a telepresence robot action modifier. The telepresence robot may rotate an upper portion independent from a lower portion. A remote terminal may allow an operator to control the telepresence robot using any combination of control methods, including by selecting a destination in a live video feed, by selecting a destination on a plan view map, or by using a joystick or other peripheral device.

A carrier system is provided with a wafer stage (WST) which holds a mounted wafer (W) and is also movable along an XY plane, a chuck unit (153) which holds the wafer from above in a non-contact manner above a predetermined position and is vertically movable, and a plurality of vertical movement pins (140), which can support from below the wafer held by the chuck unit (153) on the wafer stage (WST) when the wafer stage (WST) is positioned at the predetermined position above and can also move vertically. Then, flatness of the wafer (W) is measured by a Z position detection system (146), and based on the measurement results, the chuck unit(153) and the vertical movement pins (140) that hold (support) the wafer (W) are independently driven.
摘要:
A wafer table structure providing a single wafer table surface suitable for handling both wafers and film frames includes a base tray having a set of compartments formed therein by way of a set of ridges formed in or on an interior base tray surface; a hardenable fluid permeable compartment material disposed within the set of base tray compartments; and a set of openings formed in the base tray interior surface by which the hardened compartment material is exposable to negative or positive pressures. The base tray includes a first ceramic material (e.g., porcelain), and the hardenable compartment material includes a second ceramic material. The base tray and the compartment material are simultaneously machinable by way of a standard machining process to thereby planarize exposed outer surfaces of the base tray and the hardened compartment material at an essentially identical rate for forming a highly or ultra-planar wafer table surface.
