===Material restrictions===
[[File:Etch_material_layers.png|right|diagram of typical material stack during an etch]]The {{PAGENAME}} is designated as a [[{{#switch: {{#var:restriction}} | 1 = CMOS Clean | 2 = Semi-Clean| 3 = Metals | 4 = General| Undefined}}]] class tool. A full list of approved materials is included at the end of this section. In addition to the restrictions in this list, materials can be classified into four categories, detailed below: materials that may be '''etched''', materials that can be used as '''masks''', '''etch stop''' materials, and '''buried''' materials. Use of any material outside of these conditions requires approval by the LNF staff via a helpdesk ticket. ====Materials etched====Any ''lab supported'' [[photoresist]] may be etched in this tool. Other approved polymers include PDMS, parylene, and polyimide. The tool may also be used to clean wafers (no etched film). For etching any materials other than these, LNF approval is required via a helpdesk ticket. ====Mask and etch stop materials====This includes any material that will be exposed to the plasma during the process. Materials listed in the Approved materials list are allowed. Any other materials must be approved by the LNF via a helpdesk ticket. ====Approved materials====Below is a list of approved materials for the tool. ''Approved'' means the material is allowed in the tool under the conditions described above. If a material is not listed, please create a helpdesk ticket or email [] for any material restrictionsrequests or questions. <div class="NavFrame" style="font-size:100%;margin:0;border-style:none;padding:0;"> <div class="NavFrame" style="border-style:solid;background:#fff;padding:0.2em;"> <div class="NavHead" style="background:#ddd;text-align:center;">{{Big|Approved materials}}</div> <div class="NavContent" style="text-align:left;">{{#widget:ApprovedMaterials|toolid={{#var:toolid}}{{{1|}}}|header=N}}</div> </div></div>
