    Abstract: A photoresist cleaning composition for removing photoresist and ion implanted photoresist from semiconductor substrates. The cleaning composition contains supercritical CO 2 (SCCO2) and alcohol for use in removing photoresist that is not ion-implanted. When the photoresist has been subjected to ion implantation, the cleaning composition additionally contains a fluorine ion source. Such cleaning composition overcomes the intrinsic deficiency of SCCO2 as a cleaning reagent, viz., the non-polar character of SCCO2 and its associated inability to solubilize species such as inorganic salts and polar organic compounds that are present in the photoresist and that must be removed from the semiconductor substrate for efficient cleaning. The cleaning composition enables damage-free, residue-free cleaning of substrates having photoresist or ion implanted photoresist thereon.

    Abstract: Drying of patterned wafers is achieved in a manner effecting removal of water from the patterned wafers without collapse or deterioration of the pattern structures thereof. The drying is carried out in one aspect of the invention with a composition containing supercritical fluid, and at least one water-reactive agent that chemically reacts with water to form reaction product(s) more soluble in the supercritical fluid than water. Various methodologies are described for use of supercritical fluids to dry patterned wafers, which avoid the (low water solubility) deficiency of supercritical fluids such as supercritical CO2.

    Abstract translation: 图案化晶片的干燥以实现从图案化晶片中除去水而不塌陷或其图案结构劣化的方式来实现。 在本发明的一个方面中,用含有超临界流体和至少一种水反应剂的组合物进行干燥,所述水反应剂与水化学反应形成比水更易溶于超临界流体的反应产物。 描述了使用超临界流体来干燥图案化晶片的各种方法,其避免超临界流体(例如超临界二氧化碳)的(低水溶性)缺乏。
