The Tempress diffusion system is a modular horizontal furnace designed to process silicon wafers as part of the manufacturing technology of semiconductor, optical, MEMS, and solar devices. LTO is formed by using a process called LPCVD, Low Pressure Chemical Vapor Deposition. Chemical vapor deposition forms thin films on the surface of a substrate by thermal decomposition and/or reaction of gaseous compounds. The desired material is deposited directly from the gas phase onto the surface of the wafer. The important factors are gas ratio, temperature, and pressure.

The Tempress S1T2 - LTO 4" is designated as a CMOS Clean class tool. Below is a list of approved materials for the tool. Approved means the material is allowed in the tool under normal circumstances. If a material is not listed, please create a helpdesk ticket or email firstname.lastname@example.org for any material requests or questions.
There are several processes for this tool supported by the LNF, which are described in more detail on the Processes page.
In addition to these, this tool has a number of user-created recipes for etching a wide variety of materials. Some of these recipes are documented on Tempress S1T2 - LTO 4" User Processes. If you are curious if your material can be processed in this tool, please contact the tool engineers via the helpdesk ticket system.
