==Requesting New Materials==
If you do not see the film you need, you can request a new material to use as a private source.
*Unless there is a specific need, new materials will be added to the AE Evaporator or the PVD-75.
===Procedure for requesting a new material===
====Get the Material Approved====
Create a request using the [https://docs.google.com/a/lnf.umich.edu/forms/d/e/1FAIpQLSfEvrvh-iNqvC1Ghi8jfDwMWz7NHqKtJc4DFF7zJJlU4HmTeQ/viewform New PVD Material Request Form].
*Create a helpdesk ticket to inform LNF staff of your request, and to provide us with a forum to communicate with you.
*Your request will be reviewed by the LNF management and staff.
*This process can
; in some cases, take up to a month to complete. * Even if you have other materials approved, you must complete a New PVD Material Request form for every new material you bring into the PVD tools.
====Ordering the Material and any Private Shielding or Crucibles====
*'''Target dimensions or Evaporation Material volume and shape''': Once the material is approved, LNF staff will get you the information on target dimensions and any source requirements. Some targets may require bonding to a backing plate. Some evaporated materials may require a solid source.
*'''Material Purity''': In order to support
this high standard of process dependability, we require that all sources used in the sputter systems below in impurities. Purity set related terms used in the metals market is, “nines”. In the case of LNF, we require materials to have a purity value of 99.995% or greater. This is often described as, “Four Nines Five” and typically written as “4N5”. In cases where 4N5 materials are not available, contact an LNF staff to discuss your options.*'''Dedicated Shielding and Crucibles''': Users requesting new sputter materials will need to buy dedicated shielding for the material. New evaporation material requests may be requested to buy a dedicated crucible for the material.
See the [https://docs.google.com/document/d/1T- JDOeYIBeJ12SZRkltomyBGlZhSxQsC2qjnemXHMpo/view Requesting a new material] tutorial for specifics. == Support==
Due to issues of cross-contamination, process development of co-sputtered films will require the purchase of private targets and shields.
===Superuser access provides access to ===
*Modify and run VP (variable parameter) recipes
*Each material requires a designated shield for processing.
*# This is to prevent cross-contamination, and provide a more reliable maintenance schedule
*# Storage and cleaning is the responsibility of the developer.
