CNM Billing FAQ
Q. Why does the CNM charge to use equipment?
A. The CNM charges equipment use fees to offset the cost of maintenance and supplies for the equipment we offer. Equipment fees are calculated by dividing the annual cost by the annual usage for each tool.

In each equipment are there are computers that are networked such as the optical microscope computer in NST 3.110, you may also use the computer located in the NST forum, or the computer located in the 4th floor office 4.116. If none of these are available or you forget to pay for your time, you may also use your desktop computer to pay for the time you used.
Q. Do I need my account number every time I make a purchase?

Q. Why are there minimum charges and why is time recorded in blocks?
A. By implementing a minimum charge the CNM is able to offer lower hourly rates; it also makes it much easier for our users to accurately record their tool use.
Q. Do I have to make a reservation to use CNM equipment?
A. No, a reservation is not required, but is recommended for equipment that is in high demand. Remember that you are responsible for all of the time you reserve. Equipment reservation is a privilege and you will be billed for all of your reserved time if you abuse this benefit. You may cancel your reservation up to 24 hours in advance with no penalty. You will not be billed for reserved time if the equipment is not available due to a maintenance issue.
Q. What if I use the FIB for 15 minutes and find out my sample is bad but I had a four hour reservation.
A. You will need to make an online purchase for your complete four hour reservation and send an email explaining your situation to Mike Tiner firstname.lastname@example.org. You might receive a refund or credit for the unused time.
Q. What if I have a one hour FIB reservation but I use 1 hour and 15 minutes?
A. You will need to select the one hour FIB fee from the store and then select an additional ½ hour block for a total purchase of 1.5 hours.
Q. What if I went all the way through the purchase and realized I had made a big mistake when I read my confirmation?
A. We can fix mistakes that are made even after a purchase has been confirmed. Contact Mike Tiner, email@example.com with your name, UTEID, and explanation of your mistake.
Q. When I go into the cleanroom am I billed for just the time I am in the cleanroom or just the time I am using equipment?
A. CNM policy is that you must pay for all of the time you are in the cleanroom. If you use more than one tool at a time, you should pay more to offset the additional tool costs. For example, if you are using the evaporator and would like to use the microscope at the same time, you are using two tools, you would pay for the evaporator time and add the additional time for the microscope.
Q. What if I want to use a tool for several hours, but most of that time is spent on pumping the system down? Do I still need to pay for this time even if I leave the cleanroom? Why do I pay extra for additional entries into the cleanroom?
A. In this case you would need to pay for all of the time that the equipment was in use as well as the extra entry into the cleanroom. The CNM strongly encourages you to plan your work so that you can stay in the cleanroom to monitor your experiments
Q. What if I use more than one tool at a time in the cleanroom?
A. If you are using multiple tools at one time, you need to record time for each tool. As an example, say you have a reservation for three hours of evaporator time and while you are waiting for your sample to pump down you use the profilometer for one hour. You would need to record four hours total cleanroom time three hours for the evaporator and one additional hour for the profilometer.
Q. What if I want to leave the cleanroom during my experiment?
A. The CNM Staff encourage you to stay in the cleanroom while you are running an experiment for safety and cleanliness reasons. Remember that each cleanroom entry incurs a charge. If you are running a three hour experiment in the cleanroom and left after the first hour for 30 minutes you would need to purchase three hours of cleanroom time, plus an additional cleanroom entry which is listed on the cleanroom page as an additional item.
Q. What if my experiment only takes 20minutes to perform in the cleanroom?
A. You are required to purchase the one hour minimum. Gowning to enter the cleanroom is a considerable expense for the CNM, it is much better for the cleanroom if you plan your work sessions so they are several hours long as high entry traffic makes it difficult to keep the cleanroom clean.
Billing and Usage Rules for CNM
- All use must be recorded, there are no exceptions. Even if your group is receiving a grant from CNM to defer your use fees, you must still record your use. You will not be allowed to use CNM equipment if you do not follow this rule.
- You will be billed for your whole reservation unless you cancel it more than 24 hours in advance. You will not be billed for a reservation if the equipment is down.
- There is a minimum one hour cleanroom charge for entering the cleanroom. Plan your work accordingly, if you enter the cleanroom to pick up your experiment and are back out in five minutes, there is a one hour charge. If you enter the cleanroom to start the thermal evaporator and then re-enter the cleanroom to finish the cycle, you need to record an additional entry along with your tool hours to pay for the gowning expenses. If you are confused about this please see CNM staff.
- CNM does not allow cleanroom “tourists”, all cleanroom users must be trained by CNM staff and must record their time in the cleanroom.
