Abstract:
A method for fabricating a thermally stable ultralow dielectric constant film comprising Si, C, O and H atoms in a parallel plate chemical vapor deposition process utilizing plasma enhanced chemical vapor deposition ("PECVD") process is disclosed. Electronic devices containing insulating layers of thermally stable ultralow dielectric constant materials that are prepared by the method are further disclosed. To enable the fabrication of thermally stable ultralow dielectric constant film, specific precursor materials are used, such as, cyclic siloxanes and organic molecules containing ring structures, for instance, tetramethylcycloterasiloxane and cyclopentene oxide. To stabilize plasma in the PECVD reactor and thereby improve uniformity of the deposited film, CO2 is added to TMCTS as a carrier gas, or CO2 or a mixture of CO2 and O2 are added to the PECVD reactor.
Abstract:
Antireflective compositions characterized by the presence of an SiO-containing polymer having chromophore moieties and transparent moieties are useful antireflective hardmask compositions in lithographic processes. These compositions provide outstanding optical, mechanical and etch selectivity properties while being applicable using spin-on application techniques. The compositions of the invention are advantageously useful with shorter wavelength lithographic processes and/or have minimal residual acid content.
