A key integral to power electronics, semiconductor, and other uses, SiC (Silicon Carbide) material is left to the mercy of possible contamination, potentially coming from all directions. How should companies and individuals go about routinely storing and handling it.
What are Silicon Carbide Wafers?
This wide-bandgap has enough novelty factors about it – for example making it useable in increasingly higher temperatures and variable, that it is used in areas from power electronics and EVs, (Electric Vehicles) to photovoltaic and industrial use. But the same factors make its handling and storage no easier.
Storage Guidelines
So with the above in mind, just a few of the guidelines for avoiding contamination, damage and degradation of the material follows.

• Cleanliness: Very easily shall these kinds of materials become contaminated, from dust, oils and fingertip marks. Clean gloves must be worn and people must never touch the wafer surface. Cleanroom facilities of cleanroom handling should be used. – Temperature: Wafer storage should obviously be climate protected as much as possible to avoid warping as a result of thermal stresses. Wafer storage ideally would be at approximately twenty to twenty five degrees Celsius. Avoid rapid and variable temperature fluctuations as much as possible. – Humidity: Ideally relative humidity around thirty to fifty percent is optimum.Increased humidity may cause films of water (or as droplets or vapour) on the wafer surface leading which may on corroding or degrading the wafer. Desiccant packs or use of controlled environment will reduce this.
  Use Protective Packaging
  Wafers should be packed conveniently for protection impact but still containing dirt from the wafer surface. Anti-static bags or containers should also be cushioned enough that the wafer’s surface does not run the risk that is scratched. Keep Clean from Dust
  Wafers should also be kept clean from dust and additional atmospheric contamination.
  Avoid Direct Sunlight
  Last and certainly not least avoid general any source of light hitting the it including sun as it will the degrade the SiC wafers and causes the performance to be degraded on the wafer and in semiconductor use where the wafers are often exposed to UV or other high-energy light.
  Silicon Carbide Wafer Handling
  In handling, for best results, avoid contamination, electrostatics and all types of physical damage to of the following helpful tips in handling SiC wafers.
  Wear Clean Gloves.
  Always wear clean gloves which of course, prevent transmitting dust and oils to the wafer surface. A glove composed of a lint-free material such as nitrile or latex is preferred.Use Wafer Tweezers or Vacuum Suction
  Direct wafer handling should be minimised by using wafer tweezers or a vacuum suction tool. Wafer tweezers of non-metallic or at least ESD-safe materials are recommended to reduce the risk of scratch or electrical degradation.
  Prevent Electrostatic Discharge (ESD) Wafer.
  It is possible for the ESD from even a stray body could seriously impair the long term ESD, of wrist straps, ESD mats etc. is always preferable to avoid static electricity.
  Transporting Wafer
  If it is necessary to transport the SiC wafers from place to place, special transportation containers provide them with processed surfaces for better physical protection and minimum movement for each during transport breaking and bending etc.
  Long Term Storage.
  If Long Term Storage of SiC Wafers is to be the order of the day, consider these possibilities.

1. Labelling and Inventory Control
   They should be properly labelled ,of course. This will help avoid confusion in operating use, and also to keep track of exactly when the batch was received etc., so you can ensure that the within the shelf life you desire/require referred to at the outset etc.
   .2. Periodic Inspection
   Wafers though in long term storage should be inspected once in a while to see if dusting over, or if moisture has got in an undesirable way, or damage in some other form.
2. Long term Storage here we have mentioned poor and lead to damage in some other form.
3. General
   Take care in handling and storing to keep the wafer functional and relatively dirt/accretion free on the surface for best performance in such applications of great interest as that in renewable energy applications, Industrial Power Systems etc.
