SEMI E104 - Specification for Integration and Guideline for Calibration of Low-pressure Particle Monitor
NOTICE: This Standard or Safety Guideline has an Inactive Status because the conditions to maintain Current Status have not been met. Inactive Standards or Safety Guidelines are available from SEMI and continue to be valid for use.
The use of in situ particle monitoring (ISPM; particle measurements performed while the wafer resides inside the processing chamber) in low-pressure and vacuum applications provides a number of advantages for defect, process, and equipment management such as:
- Reduction of particle test wafers used for off-line tests and saving operator time,
- Optimization and real-time characterization of the process,
- Advanced process control,
- Advanced equipment control,
- Monitoring process chamber conditions, and
- Optimization of cleaning procedures and maintenance.
Therefore, ISPM achieves more equipment availability and faster ramp-up of the production, reduces cost of ownership, improves quality and yield. To reach these goals, ISPM needs to be easily integrated into new or existing process equipment and the acquisition as well as the analysis of the particle data needs to be automated. The ISPM sensor should not have any negative influence on the process and the measurement has to represent the main particle flow. The sensor should be designed to have a minimum negative impact on the parameters defined in SEMI E10 for the whole semiconductor process equipment, to achieve an advantage in capacity.
This Standard is intended to stipulate operating conditions, mechanical, electrical, and communication interfaces for the use of low-pressure particle detectors integrated in semiconductor process equipment. A guideline for a reference calibration of those sensors is intended to support correlation between measurements with different sensors.
This Standard applies to particle measurement under low-pressure and vacuum conditions in semiconductor manufacturing equipment.
