HIGH RESOLUTION LATENT IMAGE PROCESSING, CONTRAST ENHANCEMENT AND THERMAL DEVELOPMENT
20230100995 · 2023-03-30 ·

Patterning of organometallic radiation sensitive compositions is facilitated using a gaseous form of a contrast enhancing agent, which can include a carboxylic acid, an amide, a sulfonic acid, an alcohol, a diol, a silyl halide, a germanium halide, a tin halide, an amine, a thiol, or a mixture thereof, in which the mixture can be of the same class or different class of compounds. Contact with the contrast enhancing reactive compound is provided after irradiation of the organometallic composition to form a latent image. The contrast enhancing agent can be delivered before or after physical pattern development, and processing with the contrast enhancing agent can involve removal in a thermal process of some or substantially all of the non-irradiated organometallic composition. The contrast enhancing agent can be used in a dry thermal development step. If the contrast enhancing agent is used after a distinct development step, use of the contrast enhancing agent can involve improvement of the pattern quality. Apparatuses for performing processing with contrast enhancing agents are described.

Secondary electron generating composition

The present invention relates to a resist composition, especially for use in the production of electronic components via electron beam lithography. In addition to the usual base polymeric component (resist polymer), a secondary electron generator is included in resist compositions of the invention in order to promote secondary electron generation. This unique combination of components increases the exposure sensitivity of resists in a controlled fashion which facilitates the effective production of high-resolution patterned substrates (and consequential electronic components), but at much higher write speeds.

Resist composition and patterning process

A resist composition is provided comprising (A) a metal compound having formula (A-1), a hydrolysate or hydrolytic condensate thereof, or the reaction product of the metal compound, hydrolysate or hydrolytic condensate thereof with a di- or trihydric alcohol having formula (A-2), and (B) a sensitizer containing a compound having formula (B-1). The resist composition is adapted to change a solubility in developer upon exposure to high-energy radiation, has high resolution and sensitivity, and forms a pattern of good profile with minimal edge roughness after exposure. ##STR00001##
