Assignee: APPLIED MATERIALS, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  C | IPC C  H

Claim 0:
1. A semiconductor processing method comprising:
flowing a silicon-containing precursor into a substrate processing region of a semiconductor processing chamber;
flowing a boron-containing precursor and molecular hydrogen (H2) into the substrate processing region of the semiconductor processing chamber, at a boron-to-hydrogen flow rate ratio;
increasing the flow rate of the boron-containing precursor and the H2, wherein the boron-to-hydrogen flow rate ratio remains constant during the flow rate increase;
depositing a boron-and-silicon-containing layer on a substrate in the substrate processing region of the semiconductor processing chamber, wherein the boron-and-silicon-containing layer as a continuously increasing ratio of boron-to-silicon from a first surface in contact with the substrate to a second surface of the boron-and-silicon-containing layer furthest from the substrate.
