HTV-TAB®- Long-term storage of wafers

The TAB®-Long-Term Conservation Method is of decisive importance for wafers to ensure long-term processability and functionality as well. Due to the drastic reduction of aging mechanisms is possible to store wafers for up to 50 years without significant quality losses, depending on the initial condition.

Handling and optional further processing of the goods (e.g. wafer dicing, bonding and packaging) in a clean room to prevent contamination, if required, offers the highest quality standards throughout the entire storage process. In addition, an optical inspection, even of wafers if so, required by the customer, enables the clear identification of contaminations, cracks or discoloration.

Contents of the presentation: 

  • Solution strategies on how to ensure their own supply of wafers in the event of a discontinuation of the production line by the wafer manufacturer.
  • How to make the wafers available for future-oriented use for a long period of time.
  • Insights into which conditions are important when storing and stockpiling wafers, how ageing processes work and why a special conservation method is necessary to safeguard the future and prevent obsolescence.
