Die placement head with turret
Herein described is a system for the placement of dies on a substrate that uses a rotating turret carried with the die placement system to supply die placement heads necessary for the placement of various dies on a substrate, where multiple dies are to be placed, to a force application rod, thereby allowing for the rapid and efficient placement of a variety of dies on a single substrate.
Sintering device
Sintering device for sintering at least one electronic assembly, having a lower die and an upper die which is slidable towards the lower die, or a lower die which is slidable towards the upper die. The lower die forms a support for the assembly to be sintered and the upper die includes a receptacle for a pressure pad for exerting pressure directed towards the lower die, and a delimitation wall which laterally surrounds the pressure pad. The delimitation wall having an outer delimitation wall and an inner delimitation wall surrounded by the outer delimitation wall, the inner delimitation wall mounted so as to be slidable towards the outer delimitation wall and so as to be slid in the direction of the lower die such that, following the placing of the inner delimitation wall on the lower die, the pressure pad is displaceable in the direction of the lower die.
Die bonding apparatus comprising an inert gas environment
A die bonding apparatus comprising a first inert gas container having a first inert gas concentration, and a second inert gas container having a second inert gas concentration enclosed within the first inert gas container. The second inert gas concentration is higher than the first inert gas concentration. The die bonding apparatus further comprises a bond head located in the second inert gas container for receiving a die for bonding, and a third inert gas container having an inert gas environment that is separate from the first and second inert gas containers and where a substrate is locatable for die bonding. The bond head is operative to move the die between a first position within the second inert container and a second position within the third inert gas container to bond the die onto the substrate located in the third inert gas container.
Transfer device with three machine bases and transfer method thereof
A transfer device with three transfer bases comprises: a first machine base that carries a substrate; and at least one transfer assembly that is located above the first machine base, wherein the at least one transfer assembly comprises: a second machine base that carries a target device; a third machine base that is located above the second machine base; and a transfer head that is disposed on the third machine base for acquiring the target device from the second machine base and transferring the target device to a prescribed location on the substrate. In this disclosure, since the transfer assembly is located above the first machine base, a path that the transfer head needs to move along to complete the transfer process is shorter, thereby improving the production efficiency.
Methods and structures for mitigating ESD during wafer bonding
One method includes positioning a front side of a first substrate opposite a side of a second substrate, the first substrate comprising an ESD mitigation structure located at an approximate center of the front side, the second substrate comprising at least one TSV structure that extends through the side of the second substrate, the first substrate and the second substrates adapted to be positioned so as to result in the conductive coupling of the at least one TSV structure and the ESD mitigation structure, bending the first substrate to an initial contact position such that an initial engagement between the first substrate and the second substrate will result in conductively coupling between the ESD mitigation structure and the TSV structure, and engaging the first and second substrates with one another such that the ESD mitigation structure and the TSV structure are conductively coupled to one another.

Mounting device and mounting method
A mounting device includes a thermocompression bonding head, a pressure reduction mechanism, and a resin sheet feed mechanism. The thermocompression bonding head is configured to heat a semiconductor chip while holding the semiconductor chip and to bond the semiconductor chip to a joined piece by compression. The thermocompression bonding head has a suction hole in a face that holds the semiconductor chip. The pressure reduction mechanism communicates with the suction hole and is configured to reduce pressure inside the suction hole. The resin sheet feed mechanism is configured to supply a resin sheet between the thermocompression bonding head and the semiconductor chip. An electrode that protrudes from a top face of the semiconductor chip is bonded by thermocompression after being embedded in the resin sheet.
AN EYE DROP SOLUTION FOR ENHANCED HYALURONIC ACID RETENTION AND DELIVERY
The present invention provides biomaterial compositions that can immobilize HA to the ocular surfaces through an HABpep and transmembrane mucins and collagen of ocular tissues can act as anchoring sites. These biomaterial compositions provide prolonged HA binding and retention in both ex vivo and in vivo animal models. HA eye drop solutions with these the inventive biomaterials can prolong the biological and physical benefits to the ocular surface and potentially be more effective in treating eye disorders including dry eye than standard HA-eye drop presently available. Methods of making and use of the compositions are also provided.
