The D4 III-V Oven has been decomission in August 2019.

III-V Oven (D4)

The III-V Oven (D4) is used for wet thermal oxidation of III-V devices, for instance for lateral oxidation of thin AlGaAs layers to defined apertures in light-limiting diodes.

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.

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

The user manual and contact information can be found in LabManager:
