Claim Text:
1. A device for holding a plurality of semiconductor devices during thermocompression bonding, the device comprising: a body; a plurality of support surfaces at a first side of the body, each support surface being configured to hold at least one semiconductor device during thermocompression bonding; and a plurality of internal conduits within the body, each internal conduit extending from an opening of a respective one of the support surfaces at the first side of the body to an opening at a second side of the body, wherein each of the openings at the second side of the body is configured to be connected to a respective first pneumatic path to be in fluid communication therewith, each first pneumatic path having an independently controlled pneumatic suction force so that the openings of the support surfaces at the first side of the body are operative to selectively hold the one or more semiconductor devices against the support surfaces at the first side of the body or to release the same therefrom; and a closed collet passage arranged along a surface of the second side of the body which is operative to be in fluid communication with a further pneumatic path for forming an enclosed vacuum path on the body for holding the device against a heater.
