Latest Patents

Igari holds a patent for a method of depositing silicon nitride film, an apparatus for depositing film, and the silicon nitride film itself. The patent describes a process in which a silicon target and a to-be-deposited object are positioned to face each other within a vacuum chamber. A sputtering gas containing nitrogen is introduced into the chamber, and a negative potential is applied to the silicon target. This process allows for the deposition of a silicon nitride film with tensile stress on the surface of the to-be-deposited object, which is maintained in an electrically floated state. The method includes controlling the flow ratio of nitrogen gas and the potential applied to the silicon target to maintain the surface in a transition mode.
