==== Evaporation Coated 3D-Print (2026-04-25) ====
{{:gallery:2026-04-coated-petg.jpg?600|}}

We used out [[equipment:edwards-306:start|Edwards AUTO 306 Coating System]] to thermally evaporate aluminum onto a 3D-printed PETG part. It doesn't stick well, but it was a fun exercise to see what happens when a 3D-print is placed into a vacuum chamber.

==== Amogus Wafer (2026-04-12) ====

Lift-off process for coating an [[https://en.wikipedia.org/wiki/Among_Us|Among Us]] astronaut figure onto a wafer.  Check the [[https://social.fa-fo.de/@fafo/116393445047162286|Fedi post]] for a bit more info.
==== New (Old) Coating Systems (2026-03-30) ====

{{:equipment:edwards-e306a:pxl_20260401_170308034.jpg?400|}}

We managed to acquire these very nice Edwards coating systems for sputtering, thermal evaporation, and e-beam coating.
==== Interferometer Experiment for measuring STM piezo displacement (2026-01-18) ====
{{:gallery:2026-01-18-stm-interferometer.jpg?600|}}

Laser interferometer setup ([[projects:optics:start|Optics project]]) for measuring the displacement of the piezos on our [[projects:stm|Scanning Tunneling Microscope]] (STM).

Laser diode in the back, the piezo under test is in the front, and a camera to the left to record the interference fringes.

==== Michelson Interferometer (2026-01-11) ====

Basic michelson interferometer set up using our [[projects:optomech:start|3d-printed optomechanical components]].  To the far left, the fringe pattern is projected onto a piece of paper.
==== Pyrite under an SEM (2025-12-07) ====

See [[https://social.fa-fo.de/@fafo/115679126920409451]] for context.

==== Work-in-progress wet lab (2025-11-09) ====
{{:gallery:2025-11-09-wip-lab.jpg?600|}}

We managed to get our hands on some high-quality lab furniture.  This is a work-in-progress picture of the (not yet functional) wet lab at FAFO.

==== Random Interconnect Sample (2025-08-23) ====
{{:gallery:2025-08-23-interconnect.png?600|}}

Local interconnect layer of standard cell rows on one of our badly decapped samples.

==== Scanning Tunneling Microscope (2025-06-15) ====
{{:projects:stm:pxl_20250920_212713202.jpg?600|}}

Business end of our DIY [[projects:stm|Scanning Tunneling Microscope]] (STM). You can see the tungsten wire tip barely above a shard of DVD that we were trying to image.
==== RP2350 delidded with sandpaper (2025-03-23) ====
{{:gallery:2025-03-23-rp2350.png?600|}}

The strucures of the chip are in pretty bad shape from the sanding, but the marking and copyright year are clearly visible.

Photo was taken using our [[equipment:zeiss-dsm-962:start|Zeiss DSM 962]].

==== Fractured chip (2025-03-18) ====
{{:gallery:2025-03-18-fractures-chip.png?600|}}

Fracture of a bare silicon die where the individual layers of the chip become visible.

==== Hello World Zeiss (2025-02-10) ====
{{:gallery:2025-02-10-hello-world-zeiss.png?600|}}

Our second SEM, [[equipment:zeiss-dsm-962:start|Zeiss DSM 962 (Kevin)]], right after arrival before we started putting it back together.

==== Gardena to KF 16 (2024-10-29) ====
{{:gallery:2024-10-29-gardena.png?600|}}

Our first big FAFO innovation: A gardena to KF 16 high vacuum adapter.  Did you know gardena pulls down to 1e-6mbar of vacuum pressure?
==== OSHW logo on a die (2024-10-10) ====
{{:gallery:2025-10-10-kenji-oshw.png?600|}}

The open source hardware (OSHW) logo photographed on a bare die using our [[equipment:jeol-t330a:start|JEOL JSM-T330A]].

==== Valve assembly of a JEOL JSM-T330A (2024-07-31) ====
{{:gallery:2024-07-31-valves.png?600|}}

The valve block of our [[equipment:jeol-t330a:start|JEOL JSM-T330A (Kenji)]].  What you're seeing:

  * The PCB on the left is the vacuum control board, sporting a Z80 microcontroller. This board is mysteriously undocumented so we largely reverse-engineered it here:
    * [[https://git.fa-fo.de/fafo/jeol-t330a/src/branch/main/modules/ph00524/ph00524.pdf|Reverse Engineered Schematic]] ([[https://git.fa-fo.de/fafo/jeol-t330a/src/branch/main/modules/ph00524|Sources]])
  * The left valve block right behind the PCB controls rough vacuum routing (vent, chamber, diffusion pump).  It has 4 positions which are checked using the light barriers on top.
  * The right valve block opens up the diffusion pump to the chamber once rough vacuum is reached.
    * For safety, there is a vacuum-driven clutch on this valve so it can only open when a rough vacuum is actually present.
  * On the right, the back side of the sample chamber is visible.
  * In front of the left valve block, two linear regulators are bolted to a metal plate.  These provide the vacuum controller board with 24V and 5V DC power.
