  • Patent number: 11217442
    Abstract: A method of depositing a SiN film onto a flexible substrate includes providing the flexible substrate, and depositing the SiN film onto the flexible substrate in a plasma enhanced chemical vapour deposition (PECVD) process using SiH4, N2 and H2, in which the temperature of the substrate is 200° C. or less and SiH4 is introduced into the PECVD process at a flow rate of greater than 100 sccm.
    Type: Grant
    Filed: April 25, 2019
    Date of Patent: January 4, 2022
    Assignee: SPTS TECHNOLOGIES LIMITED

  • Patent number: 10309014
    Abstract: A method of cleaning a chamber of a plasma processing device with radicals includes creating a plasma within a remote plasma source which is separated from the chamber, the plasma including radicals and ions, cleaning the chamber by allowing radicals to enter the chamber from the remote plasma source while preventing the majority of the ions created in the remote plasma source from entering the chamber, detecting a DC bias developed on a component of the chamber during cleaning; and using the detected DC bias to determine an end-point of the cleaning and, on determination of the end-point, to stop the cleaning.

  • Patent number: 9165762
    Abstract: A method of forming silicon dioxide films using plasma enhanced chemical vapor deposition (PECVD) uses tetraethyl orthosilicate (TEOS), oxygen or a source of oxygen, and hydrogen as precursors. The method can be carried out at low temperatures in a range of 125 to 175° C. which is useful for manufacturing wafers with through silicon vias.

  • Publication number: 20130288486
    Abstract: The invention relates to a method of depositing silicon dioxide films using plasma enhanced chemical vapour deposition (PECVD) and more particularly using tetraethyl orthosilicate (TEOS). The process can be carried out at standard temperatures and also at low temperatures which is useful for manufacturing wafers with through silicon vias.
