  • Patent number: 6586146
    Abstract: A method of figuring an exposure energy. A required exposure energy is calculated according to a critical dimension (CD) of an exposing layer. A first CD deviation is obtained from a layer before the exposing layer. From the first CD deviation, a first energy compensation is calculated. Whether the deviation of photoresist sensitivity of two sequential batches is less than 1% is checked. If the deviation of photoresist sensitivity of two sequential batches is less than 1%, a sum of the required exposure energy and the first energy compensation is the exposure energy applied to the exposing layer. Otherwise, a second CD deviation is commutated according to the deviation of photoresist sensitivity of two sequential batches. A second energy compensation is then obtained from the second CD deviation, and a sum of the required exposure energy and the first/second energy compensation is the exposure energy applied to the exposing layer.

  • Patent number: 6482738
    Abstract: The present invention mainly provides a method to locally form metal silicide on an integral circuit and to avoid the phenomenon of leakage current which is caused by metal silicide formed between the memory cells on the same word line. The method of present invention achieve above objectives by principally using a design rule to adequately arrange elements in proper distance. In an embodiment, in order to form metal silicide layers on an integral circuit and to avoid metal silicide formed between two neighboring memory cell on the same word line, a dielectric layer is previously formed in the spaced region between the two neighboring memory cells and is used as a mask. Thus, in a following selective etching process, a part of silicon substrate within the above spaced region can be protected and not exposed. Therefore, no metal silicide is formed in the spaced region, and the above objectives is achieved.
