SAFETY AND EMERGENCY
All users of the MTTC Cleanroom are expected to pass a written safety exam before they are granted full access to the facility. This exam is based upon materials presented in the Cleanroom safety tutorial. Emergency procedures are also covered in the safety tutorial and are posted throughout the cleanroom.

PROCESS LIST
The UNM MTTC Cleanroom supports several microfabrication and MEMS processes, including photolithography steps (resist spinning, softbake (hotplate/Blue M oven), contact exposure, bath developing, spin rinse drying, hardbake), wet etch (dedicated KOH, SC1, SC2 and HF baths), solvent /acid cleaning, RIE plasma etch (single wafer), Deep Reactive Ion Etching (DRIE, Alcatel model AMS-100-SDE), parylene coating, diffusion processing (oxidation wet and dry, N-Dope and drive, P-Dope and drive, CVD silicon nitride deposition, CVD polysilicon deposition, CVD low temperature oxide deposition), metal evaporation, E-Beam cure, forming gas diffusion, metrology (film thickness measurement, four point probe, interferometer) and SEM.

Users of the cleanroom are expected to have their process steps checked by cleanroom staff to make sure the chemicals and gasses are compatible with those supported by the cleanroom, and that procedures are within the safety guidelines of the cleanroom.

RATE STRUCTURE
For FY-09 (effective 1 Oct 2008), UNM-based researchers (academic), and federal laboratory and commercial customers (non-academic), are charged for use of the MTTC Cleanroom on a monthly billing cycle per the following schedule:

• There is no fee for use of the cleanroom for teaching lab sessions directly related to university and community college courses.
• Out-of-state trainees will be charged a lab fee of $100 per course or workshop.
• Basic Lab fee: $33.00/hour academic users; $66.00/hour non-academic users, capped at $990/month academic users; $1,980/month non-academic users. The basic lab, primarily, covers photolithography and metrology tools. There are additional hourly fees for the DRIE, Parylene and SEM tools (see below).
• Staff support fee: $37.50/hr academic users (no cap); $75.00/hr non-academic users (no cap).

• Junior Faculty will pay no fees when using students in the cleanroom who are paid off of internal start-up funds.
• Users will pay for chemicals and supplies that are not on the standard MTTC supply list, or exceed the typical consumption rate for normal MTTC cleanroom use.
• Commercial users of the cleanroom are expected to sign a Facilities Use Agreement (FUA) prior to use of the facility. A PDF of this Agreement is available for consideration.

USERS GUIDE AND SIGN UP
A Users Guide for the MTTC Cleanroom is available from the MTTC Cleanroom staff.

Sign-up sheets for the scheduling of tool use are posted in the MTTC Cleanroom facilities. Users can schedule up to two months in advance on the rolling calendar.

Priority of scheduling is:

(1) training for student labs related to regular university and community college classes,
(2) university research and development, and
(3) commercial sector use (40% of total tool-hours capacity, minimum). Computerized (internet) signup sheets, to replace current paper sheets, are expected in the future.
