FTA: <i>“Canon’s nanoimprint lithography — a technology under development for more than 15 years but which the company says is only now commercially viable — stamps chip designs on to silicon wafers rather than etching them using light.”</i><p>It seems everything old is new again. <a href="https://thechipletter.substack.com/p/leaving-arizona" rel="nofollow">https://thechipletter.substack.com/p/leaving-arizona</a>:<p><i>“there was a reason the 6800 was expensive. It was made using ‘contact lithography’, where the photomask, containing the image that is to created on the silicon die, comes into direct contact with the silicon wafer. This inevitably led, over time, to damage to the photomask, reducing yields and eventually rendering the expensive photomask unusable. Making a low-cost version of the 6800 would be impossible without a more cost-effective manufacturing process.”</i><p>Reading <a href="https://en.wikipedia.org/wiki/Contact_lithography" rel="nofollow">https://en.wikipedia.org/wiki/Contact_lithography</a> and <a href="https://en.wikipedia.org/wiki/Nanoimprint_lithography" rel="nofollow">https://en.wikipedia.org/wiki/Nanoimprint_lithography</a>, that problem doesn’t seem to have been solved, but of course, it’s possible that the lower cost more than compensates for it.
