  • Patent number: 11504825
    Abstract: 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.

  • Patent number: 11183401
    Abstract: An industrial-scale system and method for handling precisely aligned and centered semiconductor substrate (e.g., wafer) pairs for substrate-to-substrate (e.g., wafer-to-wafer) aligning and bonding applications is provided. Some embodiments include an aligned substrate transport device having a frame member and a spacer assembly. The centered semiconductor substrate pairs may be positioned within a processing system using the aligned substrate transport device, optionally under robotic control. The centered semiconductor substrate pairs may be bonded together without the presence of the aligned substrate transport device in the bonding device. The bonding device may include a second spacer assembly which operates in concert with that of the aligned substrate transport device to perform a spacer hand-off between the substrates. A pin apparatus may be used to stake the substrates during the hand-off.

  • Patent number: 10103049
    Abstract: The method and the apparatus prevents the deformation of a substrate, e.g. a wafer, supported with its edge area or periphery at a support or chuck, and also avoids the damage and/or contamination of the active area of the substrate. In particular, the substrate is mechanically supported at its peripheral or edge portion, namely in the non-active area of the substrate, only; an additional non-mechanical extended support is provided in the active area by a gas cushion. The gas cushion is generated by a controllable nozzle or purge for a distinct and controlled compensation of the downward deflection of the substrate.
