Abstract: A vaporizer is provided for vaporizing sensitive liquid precursors in semiconductor processing applications. The vaporizer uses high flow conductance with large flow area to avoid precursor decomposition. The vaporizer also uses efficient heat conduction to avoid local cold spots due to the heat loss because of the transformation from the liquid to gas phase. The vaporizer convex surface configuration also allow a more uniform distribution of the vaporized liquid precursor. In some aspects of the invention, the vaporizer distributes the precursor to a larger area, thus eliminating the need for a showerhead.

Abstract: A plasma reactor and methods for processing semiconductor substrates are described. An induction coil inductively couples power into the reactor to produce a plasma. A thin electrostatic shield is interposed between the induction coil and plasma to reduce capacitive coupling. The shield is electromagnetically thin such that inductive power passes through the shield to sustain the plasma while capacitive coupling is substantially attenuated. Reducing capacitive coupling reduces modulation of the plasma potential relative to the substrate and allows for more controllable processing.

In the process of supplying gas, a main controller outputs to a mass flow controller a flow-rate setting command signal preset for “zero flow” prior to opening a gas shut-off valve, which opens/closes a gas supply passage, and another flow-rate setting command signal set for “a specific flow rate” only after the gas shut-off valve is opened.

In this system, a first magnetic field-forming means formed of a solenoid coil and a second magnetic field-forming means are provided so that a the distribution of a direction of a magnetic line of flux on the surface of a planar plate is controlled by a combined magnetic field from the first and second magnetic field-forming means thereby controlling the distribution in degree of the interactions of the magnetic field and an electromagnetic wave. This control ensures the uniformity of a plasma under high density plasma formation conditions, thus enabling one to form a continuous plasma over a wide range of low to high densities. Thus, there can be realized a plasma processing system that ensures processing under wide plasma conditions including high-speed processing under high density conditions.

Abstract: A plasma reactor and methods for processing semiconductor wafers are described. Gases are introduced into a reactor chamber. An induction coil surrounds the reactor chamber. RF power is applied to the induction coil and is inductively coupled into the reactor chamber causing a plasma to form. A split Faraday shield is interposed between the induction coil and the reactor chamber to substantially block the capacitive coupling of energy into the reactor chamber which may modulate the plasma potential. The configuration of the split Faraday shield may be selected to control the level of modulation of the plasma potential. For etch processes, a separate powered electrode may be used to accelerate ions toward a wafer surface. For isotropic etching processes, charged particles may be filtered from the gas flow, while a neutral activated species passes unimpeded to a wafer surface.
