 Things to be really careful with:

  • Do NOT use the tweezer while the sample is wet! The tension force of the water might break the sample.
  • Be very careful when the etching reaches 6.5 hour, should check it more frequently.
  • When using the plastic box, be gentle when clicking.

KOH etching is a commonly used process for etching silicon wafers. It is a wet etching process that uses potassium hydroxide (KOH) as the etchant. Silicon wafers are first coated with a layer of photoresist. Then, KOH is applied to the wafer and the wafer is exposed to ultraviolet (UV) light. The UV light causes the KOH engagement rings to break down into smaller molecules, which etch the silicon wafer.
