Chip transferring method and the apparatus thereof

A chip transferring method, comprising:

• providing a plurality of chips on a first load-bearing structure, wherein the first load-bearing structure comprises a first surface, and each of the plurality of chips respectively comprises an attaching surface and attaches to the first surface with the attaching surface, and wherein each of the plurality of chips comprises a top surface opposite to the attaching surface;
• dividing the first load-bearing structure into a plurality of blocks, and each of the plurality of blocks comprising multiple chips of the plurality of chips;
• measuring a photoelectric characteristic value of each of the plurality of chips;
• respectively calculating an average photoelectric characteristic value of each of the plurality of blocks based on the photoelectric characteristic values of the multiple chips of each of the plurality of blocks;
• and
• transferring the multiple chips of at least two blocks of the plurality of blocks with the average photoelectric characteristic values within a same range to a second load-bearing structure.
