EXPIRED!!! The APOX furnace has been removed from the cleanroom August 2019.

Apox furnace (D1)

The APOX furnace (D1) is a Tempress horizontal furnace for oxidation silicon wafers. This furnace is dedicated for oxidation of new and clean Si wafers to form apox layers which is a very thick wet thermal oxide grown at 1075^oC. Running a batch of apox wafers (oxide thickness > 5µm) can take several weeks, depending on how thick an apox layer that is required.

This furnace is positioned in the III-V cleanroom area. Only Nanolab employees are allowed to operate the furnace.

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

 The APOX furnace (D1) is a Tempress horizontal furnace for oxidation silicon wafers. This furnace is dedicated for oxidation of new and clean Si wafers to form apox layers which is a very thick wet thermal oxide grown at 1075<sup>o</sup>C. Running a batch of apox wafers (oxide thickness > 5µm) can take several weeks, depending on how thick an apox layer that is required.
