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 including 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 includes providing a water tank that connects to 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 processing substrates to manufacture semiconductor structures thereon includes analyzing at least one first processing parameter of a first apparatus for processing a substrate, thereby yielding at least one first throughput rate of the first apparatus. At least one second processing parameter of a second apparatus is analyzed for processing the substrate, thereby yielding at least one second throughput rate of the second apparatus. The first throughput rate and the second throughput rate are compared, thereby yielding at least one comparison result for processing the substrate.

摘要:
Reducing photoresist shrinkage by plasma treatment is disclosed. A semiconductor wafer having one or more photoresist layers is plasma treated, such as plasma curing, plasma etching, and/or high-density plasma etching the wafer. After plasma treating, one or more critical dimensions on the photoresist layers is measured using an electron beam, such as by using a scanning electron microscope (SEM). The plasma treating of the wafer prior to measuring the critical dimensions using the electron beam decreases shrinkage of the photoresist layer when using the electron beam.
