Abstract:
An apparatus for depositing a thin film on a substrate by chemical vapor deposition (CVD) comprising:material containing means for containing a liquid CVD source material;material feeding means for feeding the liquid CVD source material from said material containing means to a vaporizer while keeping the CVD source material liquid;a vaporizer for vaporizing the liquid CVD source material fed from said material feeding means by heating the liquid CVD source material to a high temperature to form a CVD source material gas;a reaction chamber connected to said vaporizer by a pipe for forming a thin film on a substrate using the CVD source material gas; anda thermostatic box surrounding said reaction chamber, wherein both of said vaporizer and piping connecting said vaporizer to said reaction chamber are located within said thermostatic box.
