Claim:
1. A method, comprising: setting a first tension value of a laminating tape during a standby mode; setting a second tension value of the laminating tape during taping on a wafer, wherein the second tension value is different from the first tension value and greater than zero; setting a third tension value of the laminating tape after taping, wherein the third tension value is different from the second tension value; mounting the wafer on a taping table, wherein the taping table is stationary during taping on the wafer; feeding the laminating tape from a supply roller on a first side of the wafer to a tension roller on a second side of the wafer opposite the first side during the taping on the wafer, wherein the tension roller applies tension in the direction of feeding the laminating tape, downstream of a laminator roller; and applying the laminating tape to the wafer by moving the laminator roller from the first side of the wafer to the second side of the wafer during the taping on the wafer, wherein the first tension value is set when the laminator roller is in a standby position on the first side of the wafer, wherein the second tension value is set when the laminator roller is in a taping start position on the first side of the wafer, and wherein the third tension value is set when the laminator roller reaches a taping finish position on the second side of the wafer, wherein the standby position, taping start position, and taping finish position are in a common plane.
