摘要:
This support device has a central axis and includes: - three uprights (130), (131) and (132) extending substantially parallel to the central axis, - a plurality of series of support members spaced along the central axis, each series of support members comprising three support members (140), (141) and (142) adapted to support one wafer (W) of the plurality of wafers and extending in different essentially longitudinal directions transverse to the central axis, each support member (140), (141) and (142) being mounted directly on a separate upright, this support device being remarkable in that the directions of the three support members (140), (141) and (142) of each series of support members (135) are concurrent at a point on the central axis.

Semiconductor wafers (11) within a supporting vertical wafer tower are positioned within a vertical process chamber (12) through a lower gate valve (20) fixed to a supporting framework (37). The gate valve (20) is sealed to a similar gate (50) valve at the upper end of a movable load lock (40, 45) on the framework, within which the wafers (11) are subjected to pre-treatment and post-treatment processes. Two load locks (40, 45) are alternately used in conjunction with the process chamber (12) and a wafer loading station above an aperture (91) on the framework. In addition, a cleaning element (110) is movably mounted on the framework (37) for periodically maintaining the interior surfaces (15) of the process tube (13) within the process chamber (12).

摘要:
A wafer support for supporting a semiconductor wafer during a process including varied temperature. The wafer support includes a body having a top surface adapted to receive the semiconductor wafer so a portion of the top surface supports the wafer. The top surface has a recessed area including an inclined surface rising from a bottom of the recessed area. The inclined surface has an incline angle that is no more than about ten degrees.
摘要:
A device and a method for reducing particle exposure to substrates during thermal treatment are disclosed. Semiconductor wafers may be rotated on a device within a process chamber divided into two partial chambers such that a first partial chamber contains the substrate to be thermally treated and a second partial chamber contains at least parts of the rotation device. Between the partial chambers, a flow of gas is set such that gas from the second partial chamber is substantially prevented from passing into the first partial chamber. In this way, particles which are produced by rotation abrasion in the second partial chamber are largely prevented from passing onto the substrate to be thermally treated. This device and this method are particularly advantageous if the rotation is realized by means of a gas drive, wherein the gas used for the rotation can be introduced directly into the second partial chamber.
摘要:
A wafer boat for use in heat treatment of semiconductor wafers in a vertical furnace comprises support rods extending generally vertically when the wafer boat is placed in the vertical furnace. Fingers are supported by and extend along vertical extent of the support rods. Wafer holder platforms are adapted to be supported by groups of fingers lying in generally different common horizontal planes. The fingers are adapted to underlie the wafer holder platforms and support the platforms at the support locations. The fingers and wafer holder platforms each have a respective first overall maximum thickness. The support location of at least one of the fingers and the wafer holder platforms have a second maximum thickness less than the first overall maximum thickness.
摘要:
A heater and/or cooler chamber (1) comprises a heat storage block or chunk (3). In the block a multitude of parallel, stacked slit pockets (17) each dimensioned to accommodate a single plate shaped workpiece. Workpiece handling openings (11) of the slit pockets (7) are freed and respectively covered by a door arrangement (13). The slit pockets (7) are tailored to snuggly surround the plate shaped workpieces therein so as to establish an efficient heat transfer between the heat storage block or chunk (3) and the workpieces to be cooled or heated.
