摘要： An apparatus, system and method to compensate for the proximity effects in the imaging of patterns in a photolithography process. A light exposure of a photoresist layer is effectuated in predetermined patterns through an exposure mask having light-transmissive openings in correspondence to the predetermined patterns. The exposure mask has areas densely populated with the light-transmissive openings and areas sparsely populated with the light-transmissive openings. Light is attenuated through the densely populated light-transmissive openings by a different amount than through the sparsely populated light-transmissive openings.

摘要： 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.

摘要： A bi-focus exposure process for exposing a wafer through a mask is described. The mask comprises a plurality of first transparent hole features having a phase shift of about 0 degrees and a plurality of second transparent hole features having a phase shift of about 180 degrees, the first and the second hole features are alternatively located on a transparent substrate, and each of the hole features is substantially and adjacently surrounded by a lightly transparent material having a phase shift of about 90 degrees on the transparent substrate. The patterns of the first hole features are printed on the wafer by exposing the wafer through the mask at a first defocus smaller than 0 &mgr;m defocus. The patterns of the second hole features are printed on the wafer by exposing the wafer through the mask at a second defocus smaller than 0 &mgr;m defocus.

摘要： A method for forming different patterns using one phase shifting mask. The phase shifting mask has a bit line contact pattern and a node contact pattern thereon. The exposure pattern is changed by using different defocus conditions. In a first defocus situation, the bit line contact pattern and the node contact pattern of the PSM are simultaneously transferred to a photoresist layer. However, in a second defocus situation, only the bit line contact pattern is transferred to the photoresist layer. A phase shifting mask thus can be used in two different photolithography processes.

摘要： A method for forming the cylindrical lower electrode of a capacitor includes the steps of providing a semiconductor substrate, and then forming an insulation layer over the substrate. Next, a contact opening is formed in the insulation layer, and then a conductive layer is formed, filling the contact opening and covering the insulation layer. Subsequently, a patterned photoresist layer is formed over the conductive layer. Thereafter, silylated photoresist spacers are formed on the sidewalls of the photoresist layer. Finally, using the spacers as a mask, the photoresist layer and a portion of the conductive layer are etched away to form the cylindrical-shaped lower electrode of a capacitor.
