Abstract:
An EUV photoresist composition includes paramagnetic particles that are adapted to block EUV radiation. The magnetic manipulation of the paramagnetic particles within a deposited layer of EUV photoresist can beneficially impact focus control and the achievable line width roughness during subsequent photolithographic processing. A spin-coating apparatus for dispensing the EUV photoresist composition onto a substrate includes a plurality of concentric electromagnets located beneath the substrate that influence the distribution of the paramagnetic particles in the photoresist layer.

Claim (Index 7):
A method of depositing a layer on a substrate, comprising:\n dispensing a coating liquid comprising paramagnetic particles and a solvent onto a portion of a substrate while rotating the substrate at a first number of revolutions per minute; rotating e substrate at a second number of revolutions per minute greater than the first number to disperse the coating liquid over the substrate and form a layer comprising the paramagnetic particles; and applying attractive magnetic force to the paramagnetic particles from below the substrate to modify a distribution of the particles within the layer.
