==About==
==About==


This open-load system is dedicated to PECVD of SiO<sub>2</sub>, SiN<sub>x</sub>, SiO<sub>x</sub>N<sub>y</sub>, and a-Si using Silane (2%SiH<sub>4</sub>, 98% He), N<sub>2</sub>O, NH<sub>3</sub>, and N<sub>2</sub> gases. The sample electrode has a 270mm diameter useable area, allowing for multiple 4” wafer depositions in a single run. Standard operating temperature is 300C, but can be user changed for temps ranging anywhere from 250 to 350C. The system is equipped with a dual generator, dual frequency option for growth of low-stress Nitride films.

About

  • Films/Gases: This open-load system is dedicated to PECVD of SiO2, SiNx, SiOxNy, and a-Si using Silane (2%SiH4, 98% He), N2O, NH3, and N2 gases.
  • Size: The sample electrode has a 270mm diameter useable area, allowing for multiple 4” wafer depositions in a single run.
  • Temperature: Standard operating temperature is 300C, but can be user changed for temps ranging anywhere from 250 to 350C.
  • Low-Stress Si3N4: The system is equipped with a dual generator, dual frequency option for growth of Low-stress Nitride films.
    • These films alternate between thin (<10nm) compressive and tensile layers.
    • The Low-Stress Si3N4 film recipe are tested approx. monthly, and kept within ±100MPa. Data can be found at Recipes (below) > Low-Stress Nitride.
