The furnace is being tested.

III-V Oxidation furnace (C2)

The III-V Oxidaiont furnace (C2) is being used on August 2019 for wet oxidation of III-V devices instead of III-V Oven (D4), for instance for lateral oxidation of thin AlGaAs layers to defined apertures in light-limiting diodes.

The furnace is a Tempress horizontal furnace. A Sample is placed on the carrier quartz plate, which always be kept inside the furnace tube, and loaded to the hot furnace that filling with water vapour. The sample get oxidized at the desired time and then the furnace door will automatically open so that the oxidation stops and the sample is ready to be unloaded.

Before use, samples have to be cleaned. A short BHF dip can be used to remove any native oxide which can be difficult to penetrate by a wet thermal oxidation.

Please check the cross contamination information in LabManager before you use the furnace.

-The furnace is an old Tempress horizontal furnace. The quartz boat is loaded manually into the furnace by use of a push rod. The furnace is cooled down to room temperature when it is not being used.
-Before use, devices have to be cleaned. A short BHF dip can be used to remove any native oxide which can be difficult to penetrate by a wet thermal oxidation.
