Abstract:
Laminates comprising a foamed polyethylene layer reduces material costs but yet can be used to make user-acceptable bags and other containers to hold consumable products (such as a dry laundry detergent) that withstand the rigors of manufacturing and transporting.
Abstract:
A method of monitoring a processing system (100, 200, 300) in real-time using low-pressure based modeling techniques that include processing one or more of wafers (W) in a processing chamber (50, 104, 202), calculating dynamic estimation errors for the precursor and/or purging process, and determining if the dynamic estimation errors can be associated with pre-existing BIST rules for the process. When the dynamic estimation error cannot be associated with a pre-existing BIST rule, the method includes either modifying the BlST table by creating a new BIST rule for the process, or stopping the process when a new BIST rule cannot be created.
Abstract:
A method of creating and/or modifying a built-in self test (BIST) table for monitoring a thermal processing system (100, 200) in real-time that includes positioning a plurality of wafers (W) in a processing chamber (202) in the thermal processing system (100, 200); executing a real-time dynamic model (330) to generate a predicted dynamic process response; creating a measured dynamic process response; determining a dynamic estimation error; determining if the determined dynamic estimation error can be associated with a pre-existing BIST rule in the BIST table; creating a new BIST rule when the dynamic estimation error cannot be associated with any pre-existing BIST rule in the BIST table; and stopping the process when a new BIST rule cannot be created.

Abstract:
A method (2100) of determining wafer curvature in real-time is presented; The method (2100) includes establishing a first temperature profile for a hotplate (58, 620) surface, where the hotplate (58, 620) surface is divided into a plurality of temperature control zones. The method (2100) further includes positioning a wafer (14, 690) at a first height above the hotplate (58, 620) surface and determining a second temperature profile for the hotplate (58, 620) surface. The wafer curvature is then determined by using the second temperature profile. Also, a dynamic model (904) of a processing system (900) is presented and wafer curvature can be incorporated into the dynamic model (904).
