Dry Etch, Si Deep RIE (PlasmaTherm DSEIII) - DSE Update

We received most of the chamber assembly replacement parts today. We are still waiting on the lamps and chamber o-rings which are scheduled to be delivered in the next couple of days. Once we have all the parts, we'll start to reassemble the chamber.

I'll send out an update in the next 2-3 days.

Thanks, //Vraj Mehalana 10:58, 5 February 2024 (PST)

ICP #1 is down - Update

Replacing the battery on the board did not resolve the tool issue.

Panasonic has located a replacement board for the tool. From what I gather they need to repair and test it and are hoping to have it ready to ship by the 16th. I'd like to add that there is the possibility that this will not resolve the issue but it is the best path forward at this point.

EBeam3 Transfer Arm Upgrade - Postponed

The Transfer Arm upgrade has been postponed again, this time due to motor driver compatibility issues.

I am waiting to hear back from the manufacturer so at this time I can not reschedule yet.

I will send another notification when everything has been worked out, and I am ready to schedule the installation.

Lab Access Changes: Symmetry App

Card/Iris scanner access is still currently enabled. However we will be moving to a smartphone-based access system. IMPORTANT: check your email to setup the new smartphone access system, so you will be ready when we switch to the new system. Look for an email titled "Invitation to Access Symmetry App".
