Some general process trends

This page is supposed to gather some general process trends and good advise for designing IBE recipes.

Etch rate

Etch rate Parameters
increases with Beam current
increases with Beam voltage
increases with Beam current * Beam voltage
not significantly effected by Stage angle
not significantly effected by Accelerator voltage

Etch profile

Etch profile (goal 90dg) Parameters
improves with Low stage angle (optimum around 5-10 dg)
is effected by Beam current (low I(B)(400mA) better than high I(B)(600mA))
is effected by Accelerator voltage * Stage angle
not significantly effected by Beam voltage
