  • Description

    As the primary electron beam penetrates the resist, elastic collisions spread the beam slightly. Backscattered electrons from the substrate may be spread over several microns. The secondary electrons generated in this process impart energy to resist through inelastic collisions. This causes the physical and chemical changes in the resist that renders in more soluble than the unexposed resist.
