摘要： A method for transferring microstructures, comprising at least the steps of:
(i) bonding a plurality of microstructures formed on one surface of a supplier substrate to a silicone-based rubber layer formed on a donor substrate;
(ii) separating some or all of the plurality of microstructures from the supplier substrate and transferring the some or all of the plurality of microstructures to the donor substrate through the silicone-based rubber layer to produce the donor substrate having the plurality of microstructures temporality fixed thereon;
(iii) washing or neutralizing the donor substrate having the plurality of microstructures temporality fixed thereon;
(iv) drying the washed or neutralized donor substrate having the plurality of microstructures temporality fixed thereon; and
(v) transferring the dried donor substrate having the plurality of microstructures temporality fixed thereof so that the donor substrate can be subjected to a subsequent step. According to the method, a plurality of steps can be carried out while temporality fixing microstructures on a single donor substrate, and therefore it becomes possible to achieve the transfer of the microstructures with high efficiency without increasing the number of steps.-

摘要： The present invention is a microstructure-transfer stamp component including a substrate and a silicone-based rubber film formed on the substrate, wherein a surface of the silicone-based rubber film facing away from the substrate has one or more recesses each being closed except for a surface opening. This provides a microstructure-transfer stamp component that can optimize temporary adhesive strength of the surface of the silicone-based rubber film stamp in a short period of time.
