Abstract:
Apparatus for high productivity combinatorial (HPC) processing of semiconductor substrates and HPC methods are described. An apparatus includes a showerhead and two or more pressure-controlled one-way valves connected to the showerhead and used for controlling flow of different processing gases into the showerhead. The pressure-controlled one-way valves are not externally controlled by any control systems. Instead, these valves open and close in response to preset conditions, such as pressure differentials and/or flow differentials. One example of such pressure-controlled one-way valves is a check valve. These valves generally allow the flow only in one direction, i.e., into the showerhead. Furthermore, lack of external controls and specific mechanical designs allow positioning these pressure-controlled one-way valves in close proximity to the showerhead thereby reducing the dead volume between the valves and the showerhead and also operating these valves at high temperatures.
Abstract:
In some embodiments, apparatus are provided that provide for flexible processing in high productivity combinatorial (HPC) system. The apparatus allow for interchangeable functionality that includes deposition, plasma treatment, ion beam treatment, in-situ annealing, and in-situ metrology. The apparatus are designed so that the functionality may be integrated within a single processing chamber for enhanced flexibility.

Provided are apparatus for high productivity combinatorial (HPC) processing of semiconductor substrates and HPC methods. An apparatus includes a showerhead and two or more self-controlled one-way valves connected to the showerhead and used for controlling flow of different processing gases into the showerhead. The self-controlled one-way valves are not externally controlled by any control systems. Instead, these valves open and close in response to preset conditions, such as pressure differentials and/or flow differentials. One example of such self-controlled one-way valves is a check valve. These valves generally allow the flow only in one direction, i.e., into the showerhead.

Abstract:
Systems and methods for rapid generation of ALD saturation curves using segmented spatial ALD are disclosed. Methods include introducing a substrate, having a plurality of substrate segment regions, into a processing chamber. The substrate may be disposed upon a pedestal within the chamber. Sequentially exposing the plurality of segment regions to a precursor within the chamber at a first processing temperature. Afterwards, purging the precursor from the chamber and then sequentially exposing each plurality of segment regions to a reactant within the chamber at the first processing temperature. Afterwards, purging the reactant from the chamber. Repeat sequentially exposing the plurality of segment regions to the precursor and the reactant for a plurality of cycles. Each segment region may be sequentially exposed to the precursor for a unique processing time. The pedestal may be rotated prior to exposing each next segment region to the precursor and the reactant.
