Non-elastomeric, non-polymeric, non-metallic membrane valves for use in high-vacuum applications are disclosed. Such valves are functional even when the fluid-control side of the valve is exposed to a sub-atmospheric pressure field which may generally act to collapse/seal traditional elastomeric membrane valves.

Non-elastomeric, non-polymeric, non-metallic membrane valves for semiconductor processing equipment

An apparatus may be provided that includes a substrate having one or more microfluidic valve structures. The valve structures are non-elastomeric, non-polymeric, non-metallic membrane valves for use in high-vacuum application. Such valves are functional even when the fluid-control side of the valve is exposed to a sub-atmospheric pressure field which may generally act to collapse/seal traditional elastomeric membrane valve.

Disclosed are apparatuses and methods for performing atomic layer etching. A method may include supporting and thermally floating a substrate in a processing chamber, modifying one or more surface layers of material on the substrate by chemical adsorption, without using a plasma, while the substrate is maintained at a first temperature, and removing the one or more modified surface layers by desorption, without using a plasma, while the substrate is maintained at a second temperature, the first temperature being different than the second temperature. An apparatus may include a processing chamber and support features configured to support and thermally float a substrate in the chamber, a process gas unit configured to flow a first process gas onto the substrate, a substrate heating unit configured to heat the substrate, and a substrate cooling unit configured to actively cool the substrate.

Thermal atomic layer etch with rapid temperature cycling

An apparatus for transporting or storing at least one semiconductor wafer in an ultra-high vacuum is provided. A portable vacuum transfer pod is provided comprising an internal wafer storage chamber for storing one or more wafers and a wafer support for supporting at least one wafer within the internal wafer storage chamber. A passively capable vacuum pump capable of passive vacuum pumping is in fluid connection with the internal wafer storage chamber and is mechanically connected to the portable vacuum transfer pod. A shut off valve for opening and closing the fluid connection is between the passively capable vacuum pump and the internal wafer storage chamber.
