Title:
A constituent for applied type BPSG film formation, a substrate, and a pattern formation method
Document Type and Number:
Japanese Patent JP6250514
Kind Code:
B2
Abstract:
A composition for forming a coating type BPSG film, containing one or more silicic acid skeletal structures represented by formula (1), one or more phosphoric acid skeletal structures represented by formula (2), one or more boric acid skeletal structures represented by formula (3), and one or more silicon skeletal structures represented by formula (4), wherein the composition contains a coupling between units in formula (4). The composition is capable of forming a BPSG film that has excellent adhesiveness in fine patterning, can be easily wet etched by a removing liquid which does not cause damage to a semiconductor substrate and a coating type organic film or a CVD film mainly consisting of carbon which is required in the patterning process, can maintain the peelability even after dry etching, and can suppress generation of particles by forming it in the coating process.
