Abstract
An integrated circuit device with a substrate and a plurality of fins is provided where fin width is less than 11 nanometers, fin height is greater than 155 nanometers and spacing between any two neighboring fins is less than 30 nanometers and each fin is in non-collapsed state. An integrated circuit device with a substrate and a plurality of fins is provided where fin width is less than 15 nanometers, fin height is greater than 190 nanometers and spacing between any two neighboring fins is less than 30 nanometers and each fin is in non-collapsed state. A method for forming a fin-based transistor structure is provided where a plurality of fins on a substrate are pre-treated with at least one of a self-assembled monolayer, a non-polar solvent, and a surfactant. One or more of these treatments is to reduce adhesion and/or cohesive forces to prevent occurrence of fin collapse.
