Revision as of 09:05, 28 June 2016

This page has been created to consolidate updates following the June 4th flood that occurred in EECS 1480 (new cleanroom space). Note that ROBIN and EECS 1440 (older part of the cleanroom) were not affected. Please see below for updated status.

Facility status

Access has been reopened for EECS 1480A (e-beam / SEM bay) and the service aisle that provides access to the parylene deposition tool. As the facility cleaning progresses, access to that space will be done via the service aisle, escorted by staff, and so will only be available 6am-6pm weekdays. The rest of the 1480 space is still closed while cleaning continues.

Equipment status

Equipment Status Alternatives Comments
Furnaces stacks 1, 2, 3, 4 and 5 Off-line Alternatives available at Cornell. See below for more details and contact Pilar if you are interested. Once the facility reopens, maintenance, and re-characterization will be needed for each tube.
P5000 PECVD Off-line Pneumatic Control Board has been replaced. Heat exchanger won't flow and will need to be addressed before tool can be evaluated further. Replacement heat exchanger arriving by 7/1.
Lab 18-1 Off-line Create a ticket or email info@LNF.umich.edu with details of films/thicknesses
Lab 18-2 Off-line Create a ticket or email info@LNF.umich.edu with details of films/thicknesses. Metal depositions have been moved to the Denton explorer. Targets available in the Denton Explorer-14: Pt, Ir, Au, Ti, Cr, W, WTi, soon Al and doped-Si. Please go to the tool website

Alternative solutions and back up

Wafer mounting station

The wafer mounting station has been relocated near the LAM RIE tool

(MC)2 access for LNF users needing AFM

Furnace processing at Cornell University

  • Wet and dry Thermal Oxidation up to 1200 C
  • Ar, N2 and 5%H2 forming gas anneals 200-1100C
  • POCL3 Doping furnace for 4 and 6” wafers
  • Solid Planar Diffusion Sources of Boron and Phosphorus for 4” wafers only
  • LPCVD LTO 450 C Silane/O2
  • LPCVD Polysilicon, undoped, N+ or P+ in-situ Doped
  • LPCVD Silicon nitride — Stoichiometric, Low Stress, Hight Temp Oxide 800C

Wet benches (Acid 12, Mask 13, and Solvent 14)

Tanks were added in Acid 72 for:

  • Cr Etch
  • Gold Etch
  • Nanostrip
  • BHF

These should be used instead of Acid 12 and Mask 13.

Solvent 84 should be used instead of Solvent 14. This bench should accommodate most of the processing.


E-Beam Spinner/Hot-Plate Bench 21

Users can use the CEE 100CB spinner in 1440C to spin PMMA. 950K A2, 950K A4, and 950K A6 PMMA are available in amber bottles in the Akro bin near the top right corner of the bench.

Please create a helpdesk ticket if you don't have access to this spinner. If you are already checked out, please follow protocol particular to this bench.

You can also use the hotplates that are in 1440C for baking.

YES Plasma Stripper

A comparable O2 descum recipe has been developed on the Plasmatherm 790.

Metal Sputtering Deposition

The Denton Explorer-14 Sputter has been equipped with: Ir, Au,Pt, Cr, Ti, W, WTi. This week both Al and doped-Si sputtering deposition will be characterized.

Please write a ticket if you need training in this tool.

The Denton can't do co-sputtering or reactive sputtering. No magnetic, paramagnetic or insulating materials either

1840 6" SRD

The SRD in 1440A can do 6" wafers
