Trichlorure de bore (BCl₃)

Boron Trichloride (BCl₃) is a colorless gas used primarily as an etchant in the semiconductor industry. It is essential for creating fine patterns on silicon wafers, contributing to the production of microchips and other electronic components. This compound is favored for its ability to selectively remove materials without damaging the underlying substrate, making it a critical material in the fabrication of advanced electronic devices.
