What about associated tools for wafer packaging ?

Even if the wafers are stored properly for the 20 year expected life-cycle of the products in which they will be required, the associated tools for packaing these wafers , testing the packaged ICs , may not exist 10years down the line. How is this situation going to be handled?  With the current pace of the semiconductor industry , such scenario is quite possible.

 Nice article joseph. You said "Successful wafer storage over 10 to 20 years is possible without product degradation". What happens after 20 years, what factors degrade the wafers ? what are the main challenges to store it safely beyond 20 years ?

Semiconductor fabrication sites are protected from vibration coming through building foundations. Earthquakes however are too strong and even micro-movements can destroy nano-meter process. Japanese fabs did not report any major damage to the sites, but I am sure that any production at time of quakes and aftershocks are damaged or they have very low yield. I think this a really good idea to store ICs in wafer specifically for military needs and for spare parts in case of major production irruptions due to many reasons. Unfortunately it would be an additional cost and these runs have to be recycled just like medical emergency supplies.

Any experience with non-military equipments, such as medical equipments? The pace of change with medical electronic equipments is my point of reference.

I cant help but point out the reports which mentioned damage to wafers inside the fabs. Now, since we are talking about wafer storage and management, and from my experience of visits to a few high tech fabs in the states, I believe the fabs are actually very well insulated from the vibrations and shocks. And given that the wafers are actually handled veyr carefully, like you mention, how is it that the quake in japan was able to damage the wafers in process?

Joseph:

Considering the pace of evolution of the semiconductors, would focus on wafer storage to extend product life cycle be a cost-effective management strategy? Or is it better for product designers to take a look at product design for either portability of the product or cost-beneficial half-life of the products, therefore not worrying about the end-of-life management hassels?
