  • Patent number: 11594427
    Abstract: A substrate processing apparatus performs increasing a pressure within a processing vessel up to a processing pressure higher than a threshold pressure of a processing fluid by supplying the processing fluid into the processing vessel in which a substrate having thereon a liquid is accommodated; and supplying the processing fluid into the processing vessel and draining the processing fluid while maintaining the pressure within the processing vessel at a level allowing the processing fluid to be maintained in a supercritical state. The increasing of the pressure includes: increasing the pressure to a first pressure; and increasing the pressure to the processing pressure from the first pressure. A temperature of the substrate is controlled to a first temperature in the increasing of the pressure to the first pressure, and is controlled to a second temperature higher than the first temperature in the increasing of the pressure to the processing pressure.

  • Patent number: 10256163
    Abstract: Embodiments of the invention provide a method for treating a microelectronic substrate with dilute TMAH. In the method, a microelectronic substrate is received into a process chamber, the microelectronic substrate having a layer, feature or structure of silicon. A treatment solution is applied to the microelectronic substrate to etch the silicon, where the treatment solution includes a dilution solution and TMAH. A controlled oxygen content is provided in the treatment solution or in an environment in the process chamber to achieve a target etch selectivity of the silicon, or a target etch uniformity across the layer, feature or structure of silicon, or both by the treatment solution.

  • Publication number: 20180240684
    Abstract: A gas discharge hole 74 (205) configured to discharge a gas is provided at a position outside an edge of a substrate W held by a substrate holding unit 89 (204) within a processing chamber 81 (201). The gas discharged from the gas discharge hole 74 (205) forms a flow of the gas flowing in a direction along a first surface (front surface) of the substrate held by the substrate holding unit. A gas of a sublimation substance which is sublimated and a foreign substance included in the gas are flown along the flow of the gas to be removed from a vicinity of the substrate. The gas serves as a heat transfer medium for heat transfer from a heating unit 88 (203) to the substrate.
