A device for centering circular wafers includes a support chuck for supporting a circular wafer to be centered upon its top surface, left, right and middle centering linkage rods and a cam plate synchronizing the rectilinear motion of the left, right and middle centering linkage rods. The left centering linkage rod includes a first rotating arm at a first end and rectilinear motion of the left centering linkage rod translates into rotational motion of the first rotating arm. The right centering linkage rod comprises a second rotating arm at a first end, and rectilinear motion of the right centering linkage rod translates into rotational motion of the second rotating arm. The first and second rotating arms are rotatable around an axis perpendicular to the top surface of the support chuck and comprise a curved edge surface configured to roll against the curved edge of the circular wafer. The middle centering linkage rod includes a third alignment arm at a first end. The third alignment arm is placed in contact with the curved edge of the circular wafer and linear motion of the middle centering linkage rod in the Y-direction pushes the third alignment arm and the circular wafer toward or away from the center of the support chuck. The cam plate includes first and second linear cam profiles. The first cam profile provides rectilinear motion for the middle centering linkage rod and the second linear cam profile provides rectilinear motion for the left and right centering linkage rods.

An apparatus for removing an adhesive layer from a wafer surface includes a chuck, a contact roller, a pick-up roller and a detaping tape. The chuck supports and holds a wafer that has an adhesive layer on its top surface. The contact roller rotates around a first axis and moves linearly along a direction perpendicular to the first axis over the chuck and the supported wafer. The pick-up roller rotates around a second axis, that is parallel to the first axis. The detaping tape rolls around the contact roller and the pick-up roller, and as it rolls it attaches to the adhesive layer, and then is removed together with the adhesive layer. The contact roller has a surface that has a footprint of a circle when rolled along a flat surface.

A debonder apparatus for debonding a temporary bonded wafer pair. The clam shell reactor includes first and second isolated chambers. An upper chuck is contained within the first chamber and has a lower surface protruding into the second chamber. A lower chuck is contained within the second chamber and has an upper surface oriented parallel and opposite to the lower surface of the upper chuck. The debonder includes means for holding an unbounded surface of the first wafer onto the lower surface of the upper chuck. The first chamber pressurizing means applies pressure onto an upper surface of the upper chuck and thereby causes the lower surface of the upper chuck and the attached wafer pair to bow downward. The debonder apparatus also includes means for initiating a separation front at a point of the bonding interface of the temporary bonded wafer pair.

An industrial-scale high throughput wafer bonding apparatus includes a wafer bonder chamber extending along a main axis and comprising a plurality of chamber zones, a plurality of heater/isolator plates, a guide rod system extending along the main axis, a pair of parallel track rods extending along the main axis, and first pressure means. The chamber zones are separated from each other and thermally isolated from each other by the heater/isolator plates. The heater/isolator plates are oriented perpendicular to the main axis, are movably supported and guided by the guide rod system and are configured to move along the direction of the main axis. Each of the chamber zones is dimensioned to accommodate an aligned wafer pair and the wafer pairs are configured to be supported by the parallel track rods. The first pressure means is configured to apply a first force perpendicular to a first end heater/isolator plate. The applied first force causes the heater/isolator plates to move toward each other along the main axis and thereby causes the collapse of each chamber zone volume and the application of bonding pressure onto the wafer pairs.

The invention provides a rotatable and optionally heatable device for holding a flat substrate. The device includes a supporting means for placing and holding the substrate on a supporting surface, optionally a heater, a means for rotating the supporting means and a means for applying a fluid, e.g. a solvent, onto the side of the substrate facing the supporting surface. The fluid is applied when the supporting device for supporting and holding the substrate is caused to rotate.

A bonding device has two chucks, two gas pressure regulators and a control unit. The chucks each have a holding surface with pressure ports fluidically connected to the respective gas pressure regulator. The control unit is electrically and/or wirelessly connected to the gas pressure regulators and configured to control gas pressure regulators independently from each other. Support elements movably mounted within the pressure ports, are provided to measure the amount of substrate deflection and adjust the respective gas pressures and also to apply additional mechanical pressure to the substrates. The two chucks may be mounted on corresponding support structures so as to be thermally isolated therefrom. The temperature of the two chucks may be equalised by moving the chucks into contact. A chuck tempering device may be used for equalising the temperature of the two chucks. The bonding device is used for bonding two substrates by bonding wave propagation.
摘要:
A holding apparatus, in particular a chuck, for a substrate comprises a main body with a upper side, a carrier element arranged in a recess of the main body so as to be vertically movable such that it can be adjusted between a protruding loading position and a retracted clamping position, the carrier element comprising a support surface for placement of the substrate. The support surface has a smaller diameter than the main body. A lifting element lifts the carrier element to the loading position. The carrier element seals the recess such that a sealed cavity is provided between the main body and the carrier element, which cavity can have a negative pressure applied thereto which counteracts the effect of the lifting element.

A wafer support system has a wafer support device and a dicing frame, wherein the wafer support device has a bottom plate and a top plate. The top plate has a support surface for supporting the wafer, and the bottom plate has a maximum diameter being larger than the maximum diameter of the top plate so that the bottom plate forms a repository for the dicing frame. The dicing frame has a plate-like shape defining a center hole, wherein the minimum diameter of the center hole is larger than the maximum diameter of the top plate so that the dicing frame sinks below the upper surface of the wafer and/or the support surface. Further, a wafer support device, a wafer support system and a mask aligner are provided.
