<p>Mario,</p>
<p>There are two parts to this. Isolating the chemistries from each
other and protecting the user. We have installed spin coaters in
independent, flow controlled benches. Likewise with developers (AZ
400K 1:4, AZ300-MIF). Our users handle resists and developers <u>with
standard cleanroom attire</u> (Nitrile gloves, bunny suit, wrap
around goggles). </p>
<p>(Although this isn't part of your question, some additional
information)</p>
<ul>
<li>RCA/Piranha PPE - Tychem Apron, +2 pairs of Microflex 93-260
(3 pairs of gloves total), full coverage face shield.</li>
<li>HF PPE - PVC Apron, same PPE as above.</li>
</ul>
<p>My users are inexperienced students enrolled in our cleanroom
classes, hence the maximalist approach with single use gloves.
Other labs I know use one pair of trionic gloves for corrosives,
which they reuse.</p>

<p>Dear Network,</p>
<p>In our cleanrooms, we handle photoresists and developers with
common cleanroom apparel (coveralls, hoods, nitrile gloves and
eye protection). Do any of you require extra special aprons,
full visors and 4H gloves? I've worked in many cleanrooms and
never encountered such requirements.</p>
