    摘要: A full fill trench structure comprising a microelectronic device substrate having a high aspect ratio trench therein and a full filled mass of silicon dioxide in the trench, wherein the silicon dioxide is of a substantially void-free character and has a substantially uniform density throughout its bulk mass. A corresponding method of manufacturing a semiconductor product is described, involving use of specific silicon precursor compositions for use in full filling a trench of a microelectronic device substrate, in which the silicon dioxide precursor composition is processed to conduct hydrolysis and condensation reactions for forming the substantially void-free and substantially uniform density silicon dioxide material in the trench. The fill process may be carried out with a precursor fill composition including silicon and germanium, to produce a microelectronic device structure including a GeO2/SiO2 trench fill material. A suppressor component, e.g., methanol, may be employed in the precursor fill composition, to eliminate or minimize seam formation in the cured trench fill material.
