Semiconductor Series–LPCVD


LPCVD is to deposit a stable solid film with atmospheric compounds’ reaction on substrate surface under low pressure and heating. As the average free travel and diffusion coefficient of gases particles are high due to low working pressure, productivity can be enhanced by compact substrate loading thus to obtain high uniformity film. LPCVD is used to deposit multiple films of Poly-Si, Si3N4, SiO2, phosphor silicate glass, boron-phosphor silicate glass, n-poly and refractory metal etc. LPCVD is widely applied in manufacturing processes of semiconductor ICs, electrics & electronics, photoelectron and MEMS industry.
