Abstract:
The invention provides a method of processing a wafer using Ion Energy (IE)-related multilayer process sequences and Ion Energy Controlled Multi-Input/Multi-Output (IEC-MIMO) models and libraries that can include one or more measurement procedures, one or more IEC-etch sequences, and one or more Ion Energy Optimized (IEO) etch procedures. The IEC-MIMO process control uses dynamically interacting behavioral modeling between multiple layers and/or multiple IEC etch sequences. The multiple layers and/or the multiple IEC etch sequence can be associated with the creation of lines, trenches, vias, spacers, contacts, and gate structures that can be created using IEO etch procedures.
Abstract:
The invention provides a method of processing a wafer using multilayer processing sequences and Multi-Layer/Multi-Input/Multi-Output (MLMIMO) models and libraries that can include one or more measurement procedures, one or more Poly-Etch (P-E) sequences, and one or more metal-gate etch sequences. The MLMIMO process control uses dynamically interacting behavioral modeling between multiple layers and/or multiple process steps. The multiple layers and/or the multiple process steps can be associated with the creation of lines, trenches, vias, spacers, contacts, and gate structures that can be created using isotropic and/or anisotropic etch processes.
Abstract:
A plasma processing system includes a processing chamber, a substrate holder configured to hold a substrate for plasma processing, and a gas injection assembly. The gas injection assembly includes a first evacuation port located substantially in a center of the gas injection assembly and configured to evacuate gases from a central region of the substrate, and a gas injection system configured to inject gases in the process chamber. The plasma processing system also includes a second evacuation port configured to evacuate gases from a peripheral region surrounding the central region of the substrate.
Abstract:
A method and apparatus are provided to control the radial or non-radial temperature distribution across a substrate during processing to compensate for non-uniform effects, including radial and angular non-uniformities arising from system variations, or process variations, or both. The temperature is controlled, preferably dynamically, by flowing backside gas differently across different areas on a wafer supporting chuck to vary heat conduction across the wafer. Backside gas flow, of helium, for example, is dynamically varied across the chuck to control the uniformity of processing of the wafer. Ports in the support are grouped, and gas to or from the groups is separately controlled by different valves responsive to a controller that controls gas pressure in each of the areas to spatially and preferably dynamically control wafer temperature to compensate for system and process non-uniformities.

Abstract:
The invention can provide a method of processing a wafer using a Real-Time Parameter Tuning (RTPT) procedure to receive an input message that can include a pass-through message, a real-time feedforward message, or a real-time optimization message, or any combination thereof. The RTPT procedures can use real-time wafer thickness data to create, modify, and/or use measurement recipe data, measurement profile data, and/or measurement model data. In addition, RTPT procedures can use real-time wafer thickness data to create, modify, and/or use process recipe data, process profile data, and/or process model data.
Abstract:
Graphical User Interfaces (GUIs) are presented for configuring and setting-up dynamic sensors for monitoring tool and process performance in a semiconductor processing system. The semiconductor processing system includes a number of processing tools, a number of processing modules (chambers), and a number of sensors. The graphical display is organized so that all significant parameters are clearly and logically displayed so that the user is able to perform the desired configuration and setup tasks with as little input as possible. The GUI is web-based and is viewable by a user using a web browser.

The chamber component comprises a chamber element having a first surface on a supply side of the chamber element and a second surface on a process side of the chamber element, wherein the process side is opposite the supply side. Furthermore, the chamber component comprises a conduit extending through the chamber element from the supply side to the process side, wherein the conduit comprises an inlet configured to receive a process fluid and an outlet configured to distribute the process fluid.
Abstract:
A method and system for dynamically controlling a process chemistry above a substrate is described. The system for adjusting the process chemistry comprises a ring configured to surround a peripheral edge of a substrate in a vacuum processing system. The ring comprises one or more gas distribution passages formed within the ring and configured to supply an additive process gas through an upper surface of the ring to the peripheral region of the substrate, wherein the one or more gas distribution passages are configured to be coupled to one or more corresponding gas supply passages formed within the substrate holder upon which the ring rests.
