O2 Si1
semiconductor· O2 Si1
O2Si1 (silicon monoxide, SiO) is a ceramic semiconductor compound occupying a unique position between amorphous silica and crystalline silicon in terms of structure and electronic properties. It is primarily used in thin-film applications including optical coatings, protective layers, and integrated circuit passivation, where its partial crystallinity and tunable refractive index provide advantages over pure SiO2. The material is notable for offering a bridge between the insulating properties of silicon dioxide and the semiconducting behavior of silicon, making it valuable in optoelectronic devices and as an interface layer in advanced semiconductor processing.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
