Abstract:
A transfer substrate is configured to transfer a plurality of micro components from a first substrate to a second substrate. The transfer substrate comprises a base and a plurality of transfer heads. The base includes an upper surface. The plurality of transfer heads is disposed on the upper surface of the base, wherein each transfer head includes a first surface and a second surface opposite to each other and the transfer heads contact the base with the first surfaces thereof. A plurality of adhesion lumps is separated from each other, wherein each adhesion lump is disposed on the second surface of one of the transfer heads. A CTE of the base is different from CTEs of the transfer heads.
