    摘要: 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.

    摘要: A method for forming a shallow trench isolation is disclosed. The method avoids using any silicon nitride material to prevent the kooi effect and use spacers to protect the corner portions of the STI. A conductive layer is used to replace the conventional used silicon nitride layer in the formation of conventional STI regions. The invention also uses a dielectric layer comprising a pad oxide layer as a sacrificial oxide layer so that an additional sacrificial oxide layer is no longer needed. The conductive layer will be oxidized together with the substrate in the formation of the gate oxide layer so that the isolation quality will not be degraded.
