摘要:
A full fill trench structure is described, including a microelectronic device substrate having a high aspect ratio trench therein and filled with silicon dioxide of a substantially void-free character and substantially uniform density throughout its bulk mass. A method of manufacturing a semiconductor product also is described, involving use of specific silicon precursor compositions for forming substantially void-free and substantially uniform density silicon dioxide material in the trench. The precursor fill composition may include silicon and germanium, to produce a microelectronic device structure including a GeO2/SiO2 trench fill material. A suppressor component may be employed in the precursor fill composition, to eliminate or minimize seam formation in the cured trench fill material.
摘要:
Apparatus and method for generating ruthenium tetraoxide in situ for use in vapor deposition, e.g., atomic layer deposition (ALD), of ruthenium-containing films on microelectronic device substrates. The ruthenium tetraoxide can be generated on demand by reaction of ruthenium or ruthenium dioxide with an oxic gas such as oxygen or ozone. In one implementation, ruthenium tetraoxide thus generated is utilized with a strontium organometallic precursor for atomic layer deposition of strontium ruthenate films of extremely high smoothness and purity.

This invention includes methods of depositing silicon dioxide comprising layers in the fabrication of integrated circuitry, methods of forming trench isolation, and methods of forming bit line over capacitor arrays of memory cells. In one implementation, a semiconductor substrate having an exposed outer first surface comprising silicon-nitrogen bonds and an exposed outer second surface comprising at least one of silicon and silicon dioxide is provided. A layer comprising a metal is deposited over at least the outer second surface. A silanol is flowed to the metal of the outer second surface and to the outer first surface effective to selectively deposit a silicon dioxide comprising layer over the outer second surface as compared to the outer first surface. Other aspects and implementations are contemplated.
