Interesting. But why store the somewhat unwieldy wafer instead the packaged chip? I’d imagine that doesn’t add much cost but makes storage significantly simpler

- adrian_b 2y agoStoring the wafers avoids paying the costs for packaging and testing in the case the chips will not be needed. Moreover, the packaged chips typically require a much larger volume for their storage than the wafers. A wafer may contain many thousands of chips. The wafers are normally stored in dry nitrogen, to avoid their chemical degradation during long term storage.
