Apparatus for roll-to-roll manufacturing semiconductor parts and feeding method thereof

1. A method of roll-to-roll processing of semiconductor parts, the method comprising:

supplying to a processing unit a first material uncoiled from a first roll for processing at the processing unit;

connecting a leading board to a leading portion of the first material before the processing so that the first material led by the leading board is processed during transfer in the processing unit along a path;

cutting the leading board from the leading portion of the first material after the processing; and

if a terminal edge of the first material begins to be processed at the processing unit, connecting another leading board to a leading portion of a second material uncoiled from a second roll and supplying the second material to the processing unit for processing.

2. The method of claim 1 , further comprising applying tension in a direction of the transfer to the first material, using a tension adjusting unit disposed upstream or downstream of the processing unit,

wherein the applying tension using the tension adjusting unit comprises:

clamping the leading board to temporarily stop the transfer of the first material;

lowering down the first material to a predetermined depth in a direction perpendicular to the direction of the transfer; and

after the lowering down, resuming the transfer of the first material by unclamping the leading board.

3. The method of claim 2 , wherein the cutting is performed after the applying tension if the applying tension is performed by the tension adjusting unit disposed downstream of the processing unit, and

wherein, after the cutting, the first material is recoiled by a recoiler.
