Oxygen and humidity control in storage device

A method, comprising:

• forming an enclosed volume in a storage device with a top panel, a bottom panel, a back panel, a front panel, and two side panels;
• holding a substrate in the enclosed volume with a plurality of protrusions disposed at inner surfaces of the two side panels;
• providing a purge gas from a gas supply system to the enclosed volume via an inlet on the bottom panel;
• injecting the purge gas into a front portion of the storage device using an isolation gas device, wherein the isolation gas device is disposed on an inner surface of the top panel above the enclosed volume and adjacent to the front panel, and wherein the purge gas flows in a direction from the top panel to the bottom panel of the storage device;
• and
• venting the purge gas out of the storage device through the bottom panel.

A method, comprising:

• providing a purge gas from a gas supply system to a storage device, wherein the storage device comprises a top panel and a bottom panel;
• directing the purge gas to an isolation gas device on an inner surface of the top panel, wherein the isolation gas device is connected to the gas supply system through a gas diffuser and an isolation gas line;
• forming an isolation gas flow with the isolation gas device in a front portion of the storage device, wherein the isolation gas flow is in a direction from the top panel to the bottom panel of the storage device;
• and
• venting the purge gas out of the storage device through the bottom panel.
