1. A semiconductor process control system comprising: a first operating system; a legacy application module developed to operate in conjunction with a legacy semiconductor process control system, the legacy semiconductor process control system configured to execute a second operating system different from the first operating system, wherein the legacy application module is configured to interface with at least one semiconductor processing chamber and comprises at least one semiconductor processing application; and a hardware abstraction module configured to provide communication between the first operating system and the legacy application module, and configured to interface with the at least one semiconductor processing chamber, wherein the hardware abstraction module is configured to emulate the legacy semiconductor process control system on a register-to-register basis, such that the at least one semiconductor processing application can be performed on the semiconductor process control system without source code changes to the at least one semiconductor processing application.
