<div dir="ltr">Hi Esta, <div><br></div><div>We have a Heidelberg DWL-200 in our cleanroom, which we use to process quite a few photomasks (mostly 5", some 7"). We purchase our mask blanks from Nanofilm (<a href="http://www.nanofilm.com/about_us.php" target="_blank">http://www.nanofilm.com/<wbr>about_us.php</a>). As for storage, we keep the mask blanks in their (opaque) cassette within the litho area of our cleanroom, but without any other special storage conditions. We keep finished masks in individual storage boxes from <a href="http://www.pozzetta.com/products/products-overview.html">Pozzett</a>a.</div><div><br></div><div>Hope this helps.</div><div><br></div><div>Cheers, </div><div><br></div><div> – Aaron</div><div><br></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 dir="ltr"><div dir="ltr"><div><u style="font-size:x-small"> </u><span style="font-size:x-small"> </span><br></div><div><span style="font-size:12.8000001907349px"><font size="1"><p style="line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="color:rgb(0,0,0);font-family:Arial;white-space:pre-wrap;line-height:1.38;background-color:transparent">Aaron Hryciw, PhD, PEng</span></p><p style="line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="color:rgb(0,0,0);font-family:Arial;white-space:pre-wrap;line-height:1.38;background-color:transparent">Fabrication Group Manager</span><br></p><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-family:Arial;color:rgb(0,0,0);vertical-align:baseline;white-space:pre-wrap;background-color:transparent">University of Alberta - nanoFAB</span></p><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-family:Arial;color:rgb(0,0,0);vertical-align:baseline;white-space:pre-wrap;background-color:transparent">W1-060 ECERF Building</span></p><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-family:Arial;color:rgb(0,0,0);vertical-align:baseline;white-space:pre-wrap;background-color:transparent">9107 - 116 Street</span></p><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-family:Arial;color:rgb(0,0,0);vertical-align:baseline;white-space:pre-wrap;background-color:transparent">Edmonton, Alberta</span></p><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-family:Arial;color:rgb(0,0,0);vertical-align:baseline;white-space:pre-wrap;background-color:transparent">Canada T6G 2V4 </span><span style="font-family:Arial;color:rgb(0,0,0);vertical-align:baseline;white-space:pre-wrap;background-color:transparent"> </span><span style="font-family:Arial;color:rgb(0,0,0);vertical-align:baseline;white-space:pre-wrap;background-color:transparent"> </span><span style="font-family:Arial;color:rgb(0,0,0);vertical-align:baseline;white-space:pre-wrap;background-color:transparent">Ph: 780-940-7938</span></p><span style="font-family:Arial;color:rgb(0,0,0);vertical-align:baseline;white-space:pre-wrap;background-color:transparent"><a href="http://www.nanofab.ualberta.ca/" style="color:rgb(17,85,204)" target="_blank">www.nanofab.ualberta.ca</a></span><span style="font-family:Arial;color:rgb(0,0,0);vertical-align:baseline;white-space:pre-wrap;background-color:transparent"> </span></font></span><font color="#000000"><br></font><br></div></div></div></div></div></div></div></div></div></div></div></div>
