I never allow Zn containing materials to be deposited in any of my chambers. Exactly for that reason. Mario On 2022-08-30 2: 13 p. m. , Brian K. Olmsted wrote:

<div dir="ltr">Hi Paul,
<div><br>
</div>
<div>Others may want to add to this with their experiences, but I have used ZnO in a retort furnace using a forming gas environment and the net result was Zn contamination so bad and persistent that the furnace was decommissioned and could not be used anymore.

<p class="x_MsoNormal">We have a request to diffuse ZnO on InAs in forming gas at 450 C for 1 hour in a horizontal furnace tube. Does anyone have experience with these materials in forming gas? Would the forming gas react with either material leading to decomposition
and contamination of the furnace tube with Zn or As?</p>
