摘要：
To reduce the width of a MOSFET gate, the gate is formed with a hardmask formed thereupon. An isotropic etch is then performed to trim the gate in order to reduce the width of the gate. The resulting gate may be formed with a width that is narrower than a minimum width achievable solely through conventional projection lithography techniques.
