Filed: 1999-09-10
Abstract: PURPOSE: A lithographic process for device fabrication is provided to produce integrated circuit device which introduced by an energy sensitive material that desirable patterns of image are applied on the substrate. CONSTITUTION: A lithographic process for device fabrication in which first order diffraction information of latent images is an energy sensitive material is used to control process parameters is disclosed. A latent image is introduced into a layer of an energy sensitive resist material formed on a substrate. A beam of radiation having a wavelength of about 632.8 nm to about 325 nm is directed onto the latent image at a glancing angle that is selected to provide first order diffraction information in the reflected radiation that is collected by an objective. The first order diffraction information from the latent image is correlated with at least one parameter of the lithographic process such as, for example, focus, lamp intensity, exposure dose, exposure time, or post exposure bake. The correlation is obtained by analyzing the effect of a selected parameter on the intensity of the first order diffraction information and selecting a value for the parameter that corresponds to an acceptable intensity.
