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. Annealing in metallurgy, and material science, is a heat treatment wherein, a material is altered, causing a change in its properties such as strength, and hardness. It is a process that produces conditions by heating, and maintaining a suitable temperature, and then cooling. Annealing is used to induce softness, relieve internal stress, and to refine the structure.

Standard operating procedure

Checkout procedure

  1. Create a Help desk Ticket requesting training.
  2. LNF staff will schedule a time for initial training. After completing training the user can attempt a checkout session. It may be necessary for some users to participate in more than one training session, prior to attempting check out.
  3. Schedule a checkout session with a tool engineer via the existing Helpdesk ticket. If this checkout is successful, the engineer will authorize you on the tool.
