  • Patent number: 11978644
    Abstract: A substrate processing system includes: a batch-type processing part that collectively processes a lot including substrates arranged at a first pitch; a single-substrate-type processing part that processes the substrates of the lot one by one; and an interface part that delivers the substrates between the batch-type processing part and the single-substrate-type processing part. The batch-type processing part includes a processing bath that stores a processing solution having a lump shape or a mist shape, a first holder that holds the substrates arranged at the first pitch, and a second holder that receives the substrates arranged at a second pitch from the first holder in the processing solution. The interface part includes a transfer part that transfers the substrates held separately by the first and second holders in the processing solution, from the batch-type processing part to the single-substrate-type processing part.

  • Publication number: 20240072203
    Abstract: A method for fabricating light emitting diode (LED) dice includes the steps of: providing a substrate, and forming a plurality of die sized semiconductor structures on the substrate. The method also includes the steps of providing a receiving plate having an elastomeric polymer layer, placing the substrate and the receiving plate in physical contact with an adhesive force applied by the elastomeric polymer layer, and performing a laser lift-off (LLO) process by directing a uniform laser beam through the substrate to the semiconductor layer at an interface with the substrate to lift off the semiconductor structures onto the elastomeric polymer layer. During the laser lift-off (LLO) process the elastomeric polymer layer functions as a shock absorber to reduce momentum transfer, and as an adhesive surface to hold the semiconductor structures in place on the receiving plate.

  • Publication number: 20150321869
    Abstract: A transfer tool is provided with a grip member which can be gripped so that its axis is perpendicular to a transfer target surface or is inclined toward a direction of movement during transfer, a rotor which is held in the grip member and is able to rotate around the axis, and a transfer head which is held on the rotor with a transfer end deviated from the axis in a direction opposite to the direction of movement during transfer. The transfer tool is configured so that the transfer head can flexibly track the transfer target surface.

  • Publication number: 20150232297
    Abstract: A transfer tool set is configured such that a plurality of refills, for example, a narrow refill, a medium refill and a wide refill, are prepared and a common transfer tool main body is able to selectively accommodate any of the refills. As transfer tools constituted with the transfer tool set, a first transfer tool in which the narrow refill is installed on the common transfer tool main body, a second transfer tool in which the medium refill is installed on the transfer tool main body and a third transfer tool in which the wide refill is installed on the transfer tool main body can be cited.

  • Patent number: 8360128
    Abstract: A transfer tool of the present invention comprises a transfer head which has a folding back guide portion for folding and guiding a transfer tape and a pair of outer walls for supporting side ends of the folding back guide and in which a transfer tape passage is formed between the outer walls, a refill for holding at least the transfer head, a case capable of holding the refill such that the refill can be inserted into and pulled out from the case in one direction, and a head cap which is pivotally mounted on the case through a pivot shaft portion and rotatable between a close position where the transfer head is covered and an open position where the transfer head is exposed, wherein the head cap is located outside an inserting and pulling out locus of the transfer head when the head cap is disposed in the close position.
