  • Patent number: 6756168
    Abstract: Embodiments of the present invention relate to a method and a system for determining an exposure time of a wafer photolithography process is applied to a wafer photolithography system and is used to determine the preferred exposure time for the L(N) batch production wafer. In one embodiment, at least three batches of the batch test wafers are recalled in a time sequence and the corresponding test values are obtained. A mean value of the test values corresponding to the at least three batches of the batch test wafers is calculated with a predetermined mathematical model. The calculated mean value is compared with a predetermined qualified examination value, and a margin value between the mean value and the qualified examination value is thus determined to adjust and generate an appropriate process exposure time. The preferred process exposure time is then employed as the exposure time of the L(N) batch production wafer.

  • Patent number: 6678581
    Abstract: A method of calibrating a wafer edge gripping end effector. A wafer calibration tool is held in a stationary position simulating the position of a semiconductor wafer to be picked up by the wafer edge gripping end effector. A controller associated with a robot having an end effector attached to a robot arm thereto is turned off. The robot arm and end effector are moved to position where the first and second clamp structures on the end effector each engage a respective inner edge that in part defines a notch formed in the wafer calibration tool. An actuator driven movable clamp structure is manually advanced so that the movable clamp structure engages an inner edge that in part defines one of the notches formed in the wafer calibration tool. The controller is turned on and data regarding the location of robot arm, end effector and movable clamp structure is stored.

  • Patent number: 6646752
    Abstract: A method and an apparatus for measuring thicknesses of ultra-thin gate oxide layers are provided. In the method, a substrate that has a thin gate oxide layer formed on top is first heat treated at a temperature between about 400° C. and about 800° C. under a sub-atmospheric pressure for at least 10 seconds. The substrate is then immediately transferred, i.e., within 10 minutes, to a thickness measuring device for the accurate measurement of the thickness of the gate oxide layer. The apparatus can be provided by mounting a heating chamber juxtaposed to a thickness measuring device, such as an ellipsometer so that substrate can be immediately transferred therein between after a heat treatment step is completed. The heat treatment step of the present invention novel method is efficient in preventing the deposition of moisture and organic residue onto the surface of the thin gate oxide layer.
