I wonder if this has implications for custom home chips/prototyping. I'm sure a big issue is vibrations but something like this could remove the need for masks at least. (again, not my area so I am clobbering terminology I am sure). It may open up home fab capabilities.

I think abusing a write-off electron microscope to side step the need for masks is also an interesting idea, however, I believe acquiring wafers of sufficient quality and depositing layers to be etched could be the bigger challenge here.

And the clean environment as a whole. That's a massive investment and there are a million ways to mess that up.

In general, hobby photo-lithography projects already use DMD/DLP projectors, and some inexpensive optics.
In general, getting vanity silicon made is usually much less expensive than trying to bootstrap a fab line. =3

This reminds me of the original patents that Magic Leap had, which involved pumping light through a single optical fiber that was wiggled by piezoelectrics into a spiral to project light (https://kguttag.com/2018/01/06/magic-leap-fiber-scanning-dis...).

> The chip projected a roughly 125-micrometer image of the Mona Lisa.
This may seem small (barely visible as a dot to the naked eye), but that's also the geometric mean of the Planck length and the diameter of the observable universe. So average size actually.

I really can't follow your comment and I've been trying. Would you mind a longer explanation of what you're getting at here?

How do you even fit a video projector onto something that small, the physics feel like they shouldn't cooperate.

This might be relevant for Augmented Reality headgear.

This is actually getting close enough to manipulate the _phase_ of light! And doing that would allow creating true holograms.
Or alternative true augmented reality glasses that are not limited to one focal plane.

Srsly title should be "MEMS Array Chip the Size of a Grain of Sand Can Project Video"
not
