How to Safely Hibernate your Vacuum System

Are you looking to hibernate your DCA Thin Film system during a COVID-19 laboratory closure?   

Here are some steps to think about alongside your own procedures.  Any questions, consult your manual or contact us: info@dca.fi

  • Pump down all deposition chambers, transfer chambers and load locks to their base pressure.  This will protect activated filaments such as within RHEED source and ion gauges.
  • Close transfer gate valves.  
  • Purge process gas lines, including MFC and Gas manifold, back to the gas bottle.  If you can leave the lines under Argon, then do so.
  • Water lines should be checked for leaks.
  • Materials in your sources, can degrade over long periods.  Do you need to secure these?   Materials in crackers are a particular concern.

Is there a chance of loss of power?

  • Back-up data on PC

Set up Video Calling and have contact details published in laboratory. 

These simple considerations alongside your own laboratory checklist should ensure that your system is back to being operational as soon as you are.

We hope that you and your families stay healthy.  DCA Instruments: SERVICE & SALES

All New DCAX-60 Atom source for Oxides and Nitrides

Our all new DCAX-60 atom source is now available!

Designed to deliver neutral atomic gas species, for the growth of high-quality compound materials such as; GaN, GaInNAs, InGaN, InN, ultra-thin Al2O3 and high-K dielectrics.  As a result of having a 50mm beam diameter DCAX-60 is ideal for research of:

Nitride and Oxide MBE growth

Atomic Hydrogen surface treatments

Reactive Gas generation for UHV Sputtering and PLD applications.

 

Control is nothing without Precision

A recent delivery of a Thin Film cluster tool for an EU based customer, with precision sample handling demands has allowed us to demonstrate rapid and reliable sample transfer, followed by growth recipes and manipulation.   Why not view our LinkedIn channel, to see the movie?   Built to improve productivity, QCM motion, sample indexing and flipping are all precise, reliable and fast.

Dual-M600 MBE with Automated Transfer System installed at The University of Sheffield

DCA Instruments has installed and commissioned the dual-M600 MBE system with automated transfer at The University of Sheffield. The custom-made UHV system features two M600 MBE chambers for III-V materials, a degas/preparation chamber, an analysis chamber for SIMS, and storage chamber (for up to 20 additional wafers). The automated transfer system (ATS) comprises a central distribution chamber (CDC) with a robotic arm to perform the wafer pick-up and placement. The robot is controlled by highly-sophisticated logic software that allows the user to transfer wafers to/from available chambers, as well as electronically mark wafers/holders in order to restrict access to designated chambers and avoid cross-contamination. DCA’s extensive testing of the robot transfer process ensures high accuracy and reliability. The ATS achieves significantly faster wafer processing and consequently maximises the efficiency of the system.

Ian Farrer and his team at The University of Sheffield will be using the DCA Instruments Dual-MBE System to conduct cutting-edge research into nanostructured materials (quantum dots & wires) with the aim of developing novel technology for quantum computing applications.

 

Multi-Chamber UHV System (Sputter, PLD and MBE) with Automated Transfer installed Trinity College Dublin

DCA Instruments completed the installation of an extensive UHV Multi-Chamber System at Trinity College Dublin funded by Science Foundation Ireland. The complete system offers multiple deposition techniques with rapid deposition from the two SP450 sputter chambers, controllable high-quality material deposition with the V450 molecular beam epitaxy chamber, and lastly high-precision growth with the PLD500 pulsed laser deposition chamber.

The customised sputter chambers are of particular interest as they provide unique deposition capabilities. Two target-facing as well as six confocal sputter magnetrons are available in one chamber,  while the second sputter chamber features six 2″ confocal magnetrons and a magnetic coil positioned at substrate level that applies a magnetic field during growth. Furthermore, specially-designed sample manipulators not only form part of the ATS (automated transfer system) but also feature motorised z-motion to adjust the working distance,  tunable substrate bias to assist with growth or perform a pre-growth wafer treatment and an oxygen-compatible heater capable of uniformly heating the wafer up to 1100oC (or 950oC in an oxygen enviroment).

The PLD500 target manipulator also features a unique-design that simultaneously rocks and rotates the selected target material to ensure uniform erosion. This allows the laser source to remain stationary and removes the need for laser rastering. The target manipulator also features linear motion to adjust the working distance as desired.  The PLD500 also features; a substrate manipulator suitable for up to 2″ wafers and equipped with the same oxygen-compatible heater as the sputter chambers, a differentially pumped Torr RHEED system to allow RHEED analysis at higher pressures,

The equipment is part of the National Access Facility that allows researchers and engineers from both academia and industry to use the DCA System for materials research and technology development for novel applications.
