I have always seen manipulation at this scale done via micromanipulators (wire bonder or inside of a vacuum chamber)
When you need precision movement, the alternative to micromanipulation is using a XY stage like ASML uses.
XY let's you hold an object like a wafer or part, and move it around in certain planes while not moving in others. XY and even XYZ stages are not uncommon in vacuum chambers where parts need moved but repeatability is key.
I just used L272M today (I'm experimenting with sinusoidal stepper drivers). It's a dip8 1A dual opamp, commonly used as motor driver. Quite unobtainium these days. Lcsc only have L272D version which is soic16. I got mine as a fake (but functional) "black top" from AliExpress.

It's an obsolete part. It should not be difficult to find substitutes for power opamps. Unless you're stuck with one particular footprint of course.
That's pretty cool!
One of the nice things about hanging here, is seeing posts like this.
Of course, I suspect that I'll never have a use for this, myself.
