OTOH, I've never cracked an IC with vapor cryo.... I performed several tweaks to the Superclock chip, all of them probably had a cumulative improvement. My general, typical experience is a reduction in whiteness, sort of like a smokiness or pall settles and the tone is better, clearer... I think this is especially true with semiconductors because the dopant atoms probably find a more ordered, regular placement in the silicon or whatever substrate. The opposite happens when semiconductors are exposed to high levels of ionizing radiation, the dopant atoms are forced out of position and lose their proper function... a big problem if you're designing exploratory satellites to orbit Saturn or Jupiter, for example. It does illustrate that dopants are mobile. When a chip is made it is unlikely that the dopant is applied in perfect uniformity. The supercooling process allows the crystalline structure to settle into its most highly ordered state. So micro interal boundaries would tend to resolve. Sort of like the "self healing" property that some crystals, like quartz exhibit.... as far as the SCD-1 is concerned, the timing sounds super stable and super tight, like all the ambiguities were removed... it made the Superclock II sound damned crude (had a II, pulled it out and switched with a III)... so you get some idea of what the stock P.O.S. clock sounded like.... if I had the right chip extractor it would be interesting to hear what this does to a Tripath chip
