    • A phase-shifting mask (PSM) is provided for use in a photolithographic process in semiconductor fabrications. The phase-shifting mask includes a quartz plate and a plurality of mask pieces located at predefined locations over said quartz plate. Each of said mask pieces includes a semi-transparent masking layer formed on said quartz plate and a semi-transparent phase-shifting layer formed on the periphery of said semi-transparent masking layer. The phase-shifting mask has the benefits of facilitating auto generation of the mask patterns thereon through computer graphic means and increasing the resolution and contrast of the pattern definition in the photolithographic process.

    • A dual phase shifting mask (PSM)/double exposure lithographic process for manufacturing a shrunk semiconductor device. A semiconductor wafer having a photoresist layer coated thereon is provided. A first phase shift mask is disposed over the semiconductor wafer and implementing a first exposure process to expose the photoresist layer to light transmitted through the first phase shift mask so as to form a latent pattern comprising a peripheral unexposed line pattern in the photoresist layer. The first phase shift mask is then replaced with a second phase shift mask and implementing a second exposure process to expose the photoresist layer to light transmitted through the second phase shift mask so as to remove the peripheral unexposed line pattern.

    • A method for shrinking critical dimension of semiconductor devices includes forming a first pattern of a photoresist layer on a semiconductor device layer, by performing a blanket exposing process to expose the photoresist layer and the exposed semiconductor device layer to light having a wavelength that can be absorbed by the photoresist layer to provide the photoresist layer with a predetermined energy per unit area, thereby producing photo generated acids therein. A first thermal process is performed to diffuse the photo-generated acids formed within the photoresist layer and to equalize glass transition temperature (Tg) of the photoresist layer. A second thermal process is thereafter carried out. The first thermal process is carried out under a temperature lower than Tg of the photoresist layer.
