    摘要: System and method for improving immersion scanner overlay performance are described. One embodiment is a method of improving overlay performance of an photolithography immersion scanner comprising a wafer table having lens cooling water (“LCW”) disposed in a water channel therein, the wafer table having an input for receiving the LCW into the water channel and an output for expelling the LCW from the water channel. The method comprises providing a water tank at least one of the wafer table input and the wafer table output; monitoring a pressure of water in the water tank; and maintaining the pressure of the water in the water tank at a predetermined level.

    摘要: A method for fabricating a semiconductor device is disclosed. An exemplary method includes forming a first structure in a first layer by a first exposure and determining placement information of the first structure. The method further includes forming a second structure in a second layer overlying the first layer by a second exposure and determining placement information of the second structure. The method further includes forming a third structure including first and second substructures in a third layer overlying the second layer by a third exposure. Forming the third structure includes independently aligning the first substructure to the first structure and independently aligning the second substructure to the second structure.
