    Abstract: An etching method capable of controlling the film thickness of a hard mask layer uniformly is provided. A plasma etching is performed on a native oxide film by using an etching gas containing, for example, CF4 and Ar while a thickness of a silicon nitride film is being monitored and the etching is finished when the thickness of the silicon nitride film reaches a predetermined value. Then, a plasma etching is performed on a silicon substrate by employing an etching gas containing, for example, Cl2, HBr and Ar and using the silicon nitride film as a mask while a depth of a trench is being monitored and the etching is finished when the depth of the trench reaches a specified value.

  • Publication number: 20100200162
    Abstract: Disclosed is a substrate processing method that dissolves and deforms a photoresist film having a first pattern formed on a substrate to reshape the resist film into a second pattern. During the reflow process, an atmosphere of a thinner vapor-containing gas is established in a processing chamber. A substrate is placed on a temperature adjusting plate. The target temperature of the temperature adjusting plate is set and controlled by a control unit, and the temperature of the temperature adjusting plate is controlled by a temperature regulator based on the target temperature set by the control unit. The control unit set and controls the target temperature so that it meets the following requirement: the atmospheric temperature?the target temperature?(the atmospheric temperature+2° C.). Due to the above, the reflowing of the resist can be performed stably, while achieving a satisfactory reflow rate although it is somewhat low.
