After bonding is complete, the Si substrate is then completely etched away, leaving the glass support.
Academic text (1995) -
Preliminary experiments on n-type Si show this to be the case.
Academic text (1995) -
Since they are the most tightly bound, the Si atoms at terrace sites are removed last.
Academic text (1998) -
To accomplish this stabilization, Si atoms must be found to fill the holes of the original rest layer.
Academic text (1998) -
The high concentration of Si in the polymer suggests a weak Si/oxide bond.

Academic text (1998) -
In this case, etching requires halogen atoms to be inserted into strong Si-Si bonds.
Academic text (1998) -
Instead, the surface Si atoms spontaneously dimerize as successive layers are exposed, as in Figure 1c.
Academic text (1998) -
Since surface dimer bonds are weaker than bulk Si-Si bonds, this dimerization actually facilitates further etching.

Etymology
Si stands for silicon, and the name silicon comes from the word silica, which meant 'sand' or 'flint'. So it's easy to remember: Si comes from the stuff of sand and stones, and that is why this element is common in the earth and used in microchips and electronics.
