摘要： A coating solution is sprayed on a rotating wafer held horizontally from a nozzle provided above the wafer while the nozzle is travelling over the wafer from a wafer center to a wafer outer area, thus spirally spraying the coating solution on the wafer. The nozzle stops when the coating solution has reached the wafer outer area and the coating solution is sprayed in circle on the wafer outer area while the wafer is rotating. A coating solution including a component of a coating film and a solvent may be sprayed on a first area to be coated of the wafer and the coating solution and a solvent for the coating film may be sprayed on a second edge area located outside the first area of the wafer.

摘要： When a coating film is formed on a substrate, the inplane uniformity of the thickness of the coating film is enhanced to improve through put. Above the substrate, there are provided main and auxiliary nozzles separately movable, and monitoring means for monitoring the state of the surface of the substrate to detect the occurrence of an uncoated region on the surface of the substrate. On the basis of previously prepared coating data, a coating liquid is spirally applied on the substrate by the main nozzle. Then, if the monitoring means detects the occurrence of the uncoated region in a coated region in which the coating liquid has been applied by the main nozzle, a control part detects whether it is required to supply the coating liquid to the uncoated region. If it is required, the coating liquid is supplied to the uncoated region by the auxiliary nozzle. On the other hand, the portion of occurrence of the uncoated region has been grasped by the control part. If the uncoated region is continuously detected at the same place with respect to two substrates, it is determined that the setting of coating data is erroneous, and this is modified.

摘要： The invention includes a hermetic container provided with a substrate mount; a vacuum exhauster connected to the hermetic container; a current member; and a current member raising and lowering mechanism. When the current member is raised and lowered as a function of the pressure inside the hermetic container, a liquid flow of the coating solution on the substrate is controlled, thereby controlling the uniformity of the film thickness of the coating solution.

摘要： The present invention relates to a processing method for processing a substrate, and comprises a step of coating a coating solution on a surface of the substrate while relatively moving a coating solution discharge nozzle and the substrate and discharging the coating solution from the nozzle onto the substrate. Thereafter, the substrate is exposed to a solvent atmosphere of the coating solution or the pressure is temporarily applied thereto in a container. Thereafter, the pressure inside the container in which the substrate is housed is reduced to dry the coating solution on the substrate. According to the present invention, it is possible to narrow the so-called edge cutting width, which is at a periphery part of the substrate and is not commercialized, and to maintain an in-plane uniformity of the coating film.

摘要： In drying a coating liquid such as a resist applied to a substrate under reduced pressure, a coating film in a peripheral portion tends to lose good shape regardless of duration of a drying period, and it is difficult to set an appropriate exhaust flow rate. After the substrate is loaded in an airtight container, a pressure is reduced from atmospheric pressure to a pressure slightly higher than the vapor pressure of a solvent, for example. Then, the solvent actively evaporates from the coating liquid. Here, evacuation is performed initially based on a first flow rate set value Q1, and thereafter, it is performed based on a second flow rate set value larger than Q1. Rounding of the surface in the peripheral portion is corrected by evacuation based on Q1, and more active evaporation of a solvent component is attained by switching to Q2.
摘要翻译： 在减压下涂布抗蚀剂等涂布液的干燥中，不管干燥时间长短如何，周边部分的涂膜容易失去良好的形状，难以设定合适的排气流量。 在将基板装载到气密容器中之后，例如将压力从大气压降至略高于溶剂蒸气压的压力。 然后，溶剂从涂布液中主动蒸发。 这里，首先基于第一流量设定值Q 1进行排气，之后，基于大于Q 1的第二流量设定值进行排气。 通过基于Q 1的排气来校正周边部分的表面的四舍五入，并且通过切换到Q 2来获得更有效的溶剂成分的蒸发。
