To remove a baked and exposed resist you either stick the wafer in a oxygen plasma asher that basically just burns the resist off, or put it in a sulfuric and peroxide bath. There's a lot of acetone or similar chemicals involved so there's a danger of fire, but the upshot is that most of the stuff can burned in a high temperature furnace and reduced to a bunch of carbon without much trouble.

    So instead of having a single crystal we could end up with many small crystals aligned along the features that we are creating.

      Do you perhaps mean electromigration? Electromigration is a process which causes failure of metal interconnects. Essentially, momentum transfer bewteen moving electrons and metal atoms causes displacement of the atoms from their lattice positions, resulting in voids that break the electronic circuit. Electromigration only affects metals and will not affect the the transistor's themselves, just the interconnects between them.

      While it's true that electromigration becomes more significant as metal line sizes decrease, there are methods for reducing electromigration. Primarily these involve altering the microstructure of the metal through the use of dopants or by changing the metal deposition conditions.

The smaller the feature size gets, the more problems do we have with particles on the substrate, causing defects. Proximity lithography is suffering from defects caused by particles that form from the direct contact between the mask and the substrate. Thinking of an embossing method for resist patterning gives me a bad feeling about generated particles adhering to the stamp-mask. Especially at 10 nm feature size. Very questionable. Also, the wall angle of the patterned resist seems far off of the desired 90 degrees. The etch behaviour of such shallow slopes is difficult to control and leads to variance in etched feature size. This is an interesting lab experiment, but I cannot imagine it for high volume chip production at all.
