About

• Films/Gases: This open-load system is dedicated to PECVD of SiO₂, SiN_x, SiO_xN_y, 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.
  • The Low-Stress Si3N4 film recipe are tested approx. monthly, and kept within ±100MPa. Data can be found at Recipes (below) > Low-Stress Nitride.
