November 2011 Survey

Survey introduction

The November 2011 survey was the sixth survey carried out using a format where individual cleanroom users were asked about their view on various parts of using DTU Danchip's facilities and in particular the cleanroom facilities.
The questionaire was send to 212 registered users (based on the logging of cleanroom use) unfortunately 8 of the e-mail adresses was obsolete and thus the mails bounced, which brought the total number of potential answers to 204 . In total 57 persons answered the questionaire which means an answer fraction of 28% regardless of whether or not the bounces should be included in the total.
This page deals with the comments given as part of the questionaire. Danchip values this feedback highly.

Comments

The comments appear here as they were written in the feedback field of the questionaire. In a few cases they have been anonymized or the worst spelling mistakes corrected.

Comment 1

When using the training email, I have at some occasions needed to send an extra email after a week before I got an answer.

Dette er et ønske fra mange af vores kunder og vi er derfor gået i gang med et større projekt omkring navngivning af de forskellige sektioner i renrummet. De gamle navne bære præg af at renrummet er bygget over flere omgange og er ikke tidssvarende længere. De nye navne vil indeholde en kode der entydigt fortæller hvor i renrummet det er og sandsynligvis også et ”populær-navn” Men da de gamle navne er en del af labmanger og andre dokumentationssystemer er det desværre ikke nogen helt simpel opgave.

Comment 2

Det ville være rart hvis track 1 kom til at virke igen. Jeg har også savnet et kort over rentrummet, så ikke Danchip mennesker også har en chance for at finde ud af hvor rentrum 1 og 5 er, og lige ledes hvad de forskellige service rum kaldes officielt. Dette vil lette kommunikationen mellem brugerne og Danchip.

Comment 3

I think we should introduce the cleanroom face masks and bouffant caps. The masks are very important; I have seen many people who are talking with eachother while looking at their samples. The amount of spit that comes out when one talks is significant. Also, it might be a good idea to introduce personal acid gloves for everyone. In this way, one is 100% sure what the gloves have been used for and how clean they are. I also think that as a welcome, every new person should get his own tweezers.

Hope to receive a more timely response for the new staff brought by the new project.

Comment 6

When equipment is "out of use" it is highly desirable to have the expected ready date listed eventhough it is not for sure it is ready there. We do not always get a reply to a email when we write directly to a person. This can of cause be due to the personal is too busy in general, but it is just very clumbersome to go finde the person all the time to be able to communicate. The facility is very well run i general and the present close interaction between customer and staff make the everyday work much more effecient.

I have had a few occurances where the time for answering about a machine or training has taken several days, but usually this is not the case.

Comment 8

A lot of equipment availability issues are out of DANCHIP's hands, but this can nevertheless still be frustrating to have long turnover times with high end machines. To everyday users, availability of existing processes feels like a more immediate priority than installing new ones.

Comment 9

I'm generally very happy working in the cleanroom, however on multiple occasions I've arrived at equipment left in unacceptable states, e.g. wet benches, open plasma asher, dirty towels used for chemical spillage. Especially the fume hoods seem by some users to be regarded as a place where everything goes which is not the case. E.g. often a single wafer is place in petri dishes in the fumehood benches and left with no name or information on what is going on, this is very annoying for the next user as this person have accommodate some unknown (potentially dangerous) process. In this regard you might consider a specified fumehood station for petri dish processing, where samples can be left alone (still marked with proper names of course) hence these type processes will not clutter up the residual fumehood benches, which then is considered reserved for more dynamic processing needs. The main thing to improve an maintain the high cleanroom standard is to keep enforcing the strict guidelines of proper cleanroom behavior and you educational aspects such the safety course etc.

Comment 10

It could be nice if the current materials in the deposition systems could be seen directly in labmanager, and not e.g. in a weekly mail such as with the Alcatel. Also, labadviser is very nice - but a little sparse on the info. Maybe you could remind customers more often that they should contribute?

Comment 12

Level of cleannes in ovens is critical for our processes. It seems that this is not monitored enough. It is interesting for customer to see the control charts for this.

Comment 13

Sometimes there are not enough cleanroom wear of right size.Sometimes some equipments are very heaviliy booked. I experienced once that the old part of cleanroom was closed for more than 30 minutes without notification after the planned close. It would be nice to have drinking water in the changing room because it's very dry in the cleanroom.

Comment 14

No major issues, but two minor comments to improve the normally fine service at Danchip: 1) When training new people and they come with a new recipe, it would be good that the Danchip personel asks if the training also should include optimisation of the recipe. I have experienced that the training of a student was not optimal in terms of how to process many wafers with a new recipe. 2) When e-mailing Danchip personel there often is a long response time. I have experienced this myself, but also students and colleagues have experienced it. It is not just a matter of days, but rather one or two weeks. However, some people at Danchip do have an e-mail response time of just a day or two, which is how it should be.

It would be better to cancel the booking of equipment in advance when the technician can't make the regular equipment maintenance at that time.

Comment 16

Better information about new equipment that becomes available would be nice (what is it, what can it do, how to start using it). A more updated labadviser could be usefull (results using the equipment, general info on the equipment, images etc.). Perhaps a monthly competition on the best contribution to labadviser could help improving the site or simply more focus from Danchip personal. A lot of emails are generated by the cleanroom mailing list (equipment out of use, time slots available, reminders, general info etc.). Reading all these mails takes up too much time, hence many users simply move them to another inbox or deletes them automatically! This is a problem when important information is sent out. A separate mailing list or a special kind of email subject that can be easily identified by outlook (and thereby sorted correctly) for critical information would be very helpful in order to separate relevant emails from irrelevant emails.

I would also like to commend the Danchip staff on their adaptiveness to new challenges. Not only is new equipment introduced on a regular basis, but when a new fabrication procedure is devised the staff is quick to help iron out the details.

The III-V aligner was malfunctioning for >8 months without the proper actions taken from Danchip. I'm very unsatisfied with that.

Comment 19

Would be nice if Danchip could change some old equipment, like III-V Alligner.

Comment 20

I put "no option" because it depends what you mean with "overall satisfaction". In terms of technical stuff, I'd put "satisfied" but in terms of "overall" (like including economy transparency, prices, etc.) it's more towards "unsatisfied" or even "very unsatisfied".

Comment 21

More modern equipment, and more service on the equipment so they won't be down for a week at the time...".
