Abstract | Disclosed herein is a plasma chamber setting method for generating plasma in a plasma chamber. A plurality of plasma source coils, including a first plasma source coil, a second plasma source coil having an etching rate at the center part thereof higher than that of the first plasma source coil, and a third plasma source coil having an etching rate at the edge part thereof higher than that of the first plasma source coil, are prepared. The first plasma source coil is disposed on the plasma chamber, and a test wafer is etched. The etching rate for each position of the test wafer is analyzed, and first plasma source coil is replaced with the second plasma source coil or the third plasma source coil based on the analysis results.
<La présente invention se rapporte à un procédé de réglage d'une chambre à plasma permettant de générer du plasma dans une chambre à plasma. Une pluralité de bobines source de plasma sont préparées, ces bobines incluant une première bobine source de plasma, une deuxième bobine source de plasma ayant un facteur de gravure en sa partie centrale supérieur à celui de la première bobine source de plasma, et une troisième bobine source de plasma ayant un facteur de gravure au niveau de sa partie latérale supérieur à celui de la première bobine source de plasma. La première bobine source de plasma est disposée sur la chambre à plasma et une plaquette d'essai est gravée. Le facteur de gravure pour chaque position de la plaquette d'essai est analysé, et la première bobine source de plasma est remplacée par la deuxième bobine source de plasma ou par la troisième bobine source de plasma en fonction des résultats de cette analyse. > |
