The act of controlling a semiconductor manufacturing process within established specifications and/or acceptable deviations

Automated control of a process, such as an assembly line.

Using densitometric and colorimetric measurement data from press sheet color bars to monitor press performance throughout the press run. Data is analyzed in relation to established control limits. See Control Limits.

The automated control of a processing plant such as a petrochemical works, where input flow and control is regulated by various output sensor measurements.

A quality control procedure in which sampling is done during the transformation process to determine whether the process itself is under control.

(n) The measurement, analysis, and adjustment of manufacturing processes, such as drilling, milling, and turning. The quality of a product relies heavily on process control techniques used to check the variability of machined parts and to detect defects. The use of statistical techniques is an important component of process control.

In manufacturing systems, the regulation of variables that influence or control the conduct of a process so that a specified quality and quantity of products are obtained. See SPC (statistical process control).

Automatic monitoring and control of a process by an instrument or system configured or programmed to respond appropriately to process feedback.

Automatic monitoring and control of a process by an instrument or computer programmed to respond appropriately to feedback from the process. (7/96)

System calls that allow a process to control its own execution. A process can allocate memory, lock itself in memory, set its scheduling priorities, wait for events, execute a new program, or create a new process.

The act of controlling the key parameters of a process to try to ensure product consistency.

Process control is a statistics and engineering discipline that deals with architectures, mechanisms, and algorithms for controlling the output of a specific process. See also control theory.
