Abstract:
Exemplary semiconductor processing systems may include a processing chamber, and may include a remote plasma unit coupled with the processing chamber. Exemplary systems may also include a mixing manifold coupled between the remote plasma unit and the processing chamber. The mixing manifold may be characterized by a first end and a second end opposite the first end, and may be coupled with the processing chamber at the second end. The mixing manifold may define a central channel through the mixing manifold, and may define a port along an exterior of the mixing manifold. The port may be fluidly coupled with a first trench defined within the first end of the mixing manifold. The first trench may be characterized by an inner radius at a first inner sidewall and an outer radius, and the first trench may provide fluid access to the central channel through the first inner sidewall.

Claim (Index 19):
A method of etching silicon oxide in a semiconductor processing system, the method comprising:\n delivering a nitrogen-containing precursor or hydrogen into an adapter external a processing chamber housing a substrate including an exposed region of silicon oxide; flowing ammonia into the adapter; mixing the ammonia with the nitrogen-containing precursor or the hydrogen to produce a first mixture; flowing the first mixture to a mixing manifold; flowing hydrogen fluoride into the mixing manifold, wherein the mixing manifold comprises nickel plating or ceramic; mixing the hydrogen fluoride with the first mixture to produce a second mixture; delivering the second mixture into the processing chamber; and etching the silicon oxide with the second mixture.
