Abstract
By performing an anisotropic resist modification prior to the actual resist trimming process, the profile of the end portions of the resist features may be significantly enhanced, for instance by providing substantially vertical sidewall portions. Consequently, an overlap of gate electrodes with the respective isolation structures may be obtained, while nevertheless the probability for a short circuit between opposing end portions of the gate electrodes may be significantly reduced, thereby providing the potential for further scaling down device dimensions.
