摘要： A semiconductor process technique to help reduce semiconductor process effects, such as undesired line edge roughness, insufficient lithographical resolution, and limited depth of focus problems associated with the removal of a photoresist layer. More particularly, embodiments of the invention use a photoacid generator (PAG) material in conjunction with a sacrificial light absorbing material (SLAM) to help reduce these and other undesired effects associated with the removal of photoresist in a semiconductor manufacturing process. Furthermore, embodiments of the invention allow a PAG to be applied in a semiconductor manufacturing process in an efficient manner, requiring fewer processing operations than typical prior art techniques.

摘要： Electric fields may be advantageously used in various steps of photolithographic processes. For example, prior to the pre-exposure bake, photoresists that have been spun-on the wafer may be exposed to an electric field to orient aggregates or other components within the unexposed photoresist. By aligning these aggregates or other components with the electric field, line edge roughness may be reduced, for example in connection with 193 nanometer photoresist. Likewise, during exposure, electric fields may be applied through uniquely situated electrodes or using a radio frequency coil. In addition, electric fields may be applied at virtually any point in the photolithography process by depositing a conductive electrode, which is subsequently removed during development. Finally, electric fields may be applied during the developing process to improve line edge roughness.

In addition, by using chain scission technology, line edge roughness and resolution may be improved at the same time.

摘要翻译：电场可以有利地用于光刻工艺的各个步骤。例如，在预曝光烘烤之前，已经旋涂在晶片上的光致抗蚀剂可以暴露于电场以取向未曝光的光致抗蚀剂内的聚集体或其它组分。通过将这些聚集体或其它组分与电场对准，可以减少线边缘粗糙度，例如与193纳米光致抗蚀剂结合。同样地，在曝光期间，可以通过独特的电极或使用射频线圈施加电场。此外，可以通过沉积导电电极在光刻工艺中的几乎任何点处施加电场，导电电极随后在显影期间被去除。最后，可以在显影过程中施加电场以改善线边缘粗糙度。

摘要： Several techniques are described for modulating the etch rate of a sacrificial light absorbing material (SLAM) by altering its composition so that it matches the etch rate of a surrounding dielectric. This particularly useful in a dual damascene process where the SLAM fills a via opening and is etched along with a surrounding dielectric material to form trenches overlying the via opening.
