Abstract
In one embodiment, a method of fabricating a device having at least two features of differing heights comprises: depositing a resist over a substrate; determining a topography pattern for the at least two features of the device; determining an exposure pattern for the at least two features of the device; exposing a first area of the resist with a first dose of light, the first area corresponding to a first feature of the at least two features; exposing a second area of the resist with a second dose of light that is different from the first dose of light, the second area corresponding to a second feature of the at least two features; and developing the resist.
