The present invention discloses a substrate configured to receive a plurality of micro elements on a carrier board. The substrate comprises a body, a first conductive bump, and a second conductive bump. The body has a first surface, a transfer area is defined within the first surface, and a central portion and a peripheral portion is defined within the transfer area. The first conductive bump, disposed on the central portion, has a first volume. The second conductive bump, disposed on the peripheral portion, has a second volume. Wherein the first volume is different from the second volume. 1. A substrate , configured to receive a plurality of micro elements on a carrier board , comprising:a body having a first surface;a first conductive bump, disposed on a central portion, having a first volume; anda second conductive bump, disposed on a peripheral portion, having a second volume;wherein a transfer area is defined within the first surface, and the central portion and the peripheral portion is defined within the transfer area;wherein the first volume is different from the second volume.2. The substrate according to claim 1 , wherein the first conductive bump has a first thickness claim 1 , the second conductive bump has a second thickness claim 1 , and when the first volume is smaller than the second volume claim 1 , the first thickness is smaller than the second thickness.3. The substrate according to claim 2 , wherein the first conductive bump has a first contact area on the first surface claim 2 , the second conductive bump has a second contact area on the first surface claim 2 , and the first contact area and the second contact area are the same.4. The substrate according to claim 1 , wherein the first conductive bump has a first contact area on the first surface claim 1 , the second conductive bump has a second contact area on the first surface claim 1 , and when the first volume is smaller than the second volume claim 1 , the first contact area is smaller than ...
