Interesting!
Do they start with a curved piece of silicon and do the fabbing on that? Or is it initially flat and then bent during the process?
Will this be generally isolated to very specialty wide-field imaging? And expensive, custom runs?
- BostonEnginerd 6y agoI would expect the sensors are manufactured flat, back thinned down to where Si is flexible and then mounted onto a curved support structure. It looks like their US patent is here: https://patentimages.storage.googleapis.com/10/b3/ee/69d396b97984e7/US10109670.pdf https://patentimages.storage.googleapis.com/10/b3/ee/69d396b...
- supernova87a 6y agoHow interesting! By the way, this brings back thoughts how astronomy used to be done with thin glass plates, doing wide area sky surveys. The plates would be placed into the plate holder, and some pressure was necessary to deform the plate to match the curvature desired. They said you knew when you'd gone to far because you'd hear the tinkle of broken glass... (they also baked the plates in hydrogen to increase their light sensitivity)
