· SiP

Silicon phosphide (SiP) is a binary III-V semiconductor compound combining silicon with phosphorus, representing an emerging material in the semiconductor research space. While not yet widely deployed in high-volume production, SiP is of interest for potential optoelectronic and high-speed electronic applications where III-V semiconductors offer advantages over conventional silicon, such as direct bandgap properties and higher electron mobility. Engineers and researchers consider SiP as part of broader efforts to develop heteroepitaxial III-V devices on silicon substrates, which could enable monolithic integration of photonic and electronic functions on mainstream silicon manufacturing platforms.

Export Control

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.
