<div dir="ltr">Vincent Luciani,<div><br></div><div>In 1985 the UC Berkeley Microlab began using the gowning model most universities adapt - Nylon fabric or Gortex gowns, boot covers and hoods, probably owned by a laundry service. Our service delivered clean gowns and picked up the dirty gowns which they owned. We got suspicious as we regularly got screwed with reports of lost or damaged gowns. Plus this particular service surreptitiously renewed two-year contracts every time an invoice got signed. Getting rid of them was like switching mobile phone companies or internet providers. </div><div><br></div><div>Our manager at that time was not one to take a threat. He told them to go to Hell and where to find their gowns for removal. </div><div><br></div><div>We switched to disposable monofilament polypro gowns (Tyvek) for a significant savings. Each lab member gets a gowning box to keep their gown in and their asked to replace gowns on a regular bais. This works well. In my 37 years associated with the Microlab and its successor, the Marvel NanoLab we have not revisited this decision. Having said this, I cannot say we've done any recent cost analysis, either.</div><div><br></div><div>I can say our relaxed gowning has <u>never</u> resulted in a report of yield issues. No one has failed to make what they wanted in our labs because of ambient particle issues. </div><div><br></div><div>It is difficult to understand why research labs takes such pains to mimic production fabs. If we were in the microprocessor business, with a billion transistors on a chip and pushing 95%+ yields things would have to be different. Fortunately we don't make microprocessors and and likely neither do you. University and Government labs are not there or funded to make such devices. </div><div><br></div><div>Regards,<br></div><div>Bob Hamilton</div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div><div><div><div><div><br>Robert Hamilton<br></div>University of CA, Berkeley<br>Marvell NanoLab Equipment Manager<br></div>Rm 520 Sutardja Dai Hall, MC 1754<br></div>Berkeley, CA 94720<br></div>Phone 510-809-8618 (desk - preferred)<br></div>Mobile 510-325-7557 (my personal mobile)<br></div>E-mail preferred: <a href="mailto:bob@eecs.berkeley.edu" target="_blank">bob@eecs.berkeley.edu</a><br><a href="http://nanolab.berkeley.edu/" target="_blank">http://nanolab.berkeley.edu/</a></div><div dir="ltr"><br></div><div dir="ltr"><br><div><div><div><div><div><div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div>

<p class="MsoNormal">Hello LabNetwork,<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">A new problem has come up for us and we have not been able to resolve the issue with the vendor. The contractor is adamant in discarding and charging us for stained or damaged garments at a startling frequency. The cost associated with
this have become prohibitively expensive and prominent on my radar screen.<u></u><u></u></p>
<p class="MsoNormal">I now have an opportunity to rethink that arrangement which is a fleeting opportunity for me simply due to the bureaucracy and lead time associated with the government acquisition requirements.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Current practice:<u></u><u></u></p>
<p class="MsoNormal">Our cleanroom is class 100 and since our beginning (10 years ago), we have gone the conventional route of contracting with a vendor to supply and launder our Gore-Tex garments (bunny suits, hoods, booties, frocks). Currently, we collect
all garments every Friday so users get a fresh set weekly. We have about 100 different users weekly so swap out about 100 hoods/suits/booties per week.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">So, I will take this opportunity to reach out to the collective wisdom of the LabNetwork to see how others have contained the costs of cleanroom garments.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
