1. Rationale:
a. Describe the need or problem addressed by this activity.
(Indicate the customer, what benefits they will receive, and if possible, quantify the impact on the return on investment [ROI] if the Document is implemented.)
SEMI E113 was developed to provide standardized testing and evaluation methods that can be used to assess the performance of the RF power-delivery systems and control instrumentation on a chamber so that such systems can satisfy the RF reliability and repeatability demands. It was the intention of the original E113 to characterize not only the RF power-supply side of the subsystems (i.e., the generator, cable assemblies, matching network), but also the performance of the integrated system (i.e., entire RF circuit including RF power-delivery interface [chuck/coil] and process-chamber instrumentations).

While the original approach is more holistic and ideal for addressing issues in wafer-processing results that are predominantly caused by issues in reliability and repeatability of the process plasma, characterizing an integrated system may not be practical for subsystem suppliers and even for the plasma processing-equipment supplier as performance and stability of other subsystems, such as gas distribution/delivery subsystems, pressure-control subsystems, or chamber/components temperature-control systems, can also affect the load side of the condition in plasma-processing equipment. As a result, the scope of characterization in this Standard is often too wide to realize the reproducible testing or evaluation specified in this Standard. At the fab floor, it is very important to have judgement criteria to determine if any of the indispensable subsystems, such as the RF power-delivery subsystem, of the equipment is in good shape or not, individually.
For a complex problem that is caused by the irregularity of characteristics defined by more than one subsystem, confirming whether or not each subsystem itself is functioning/performing up to its respective specification is the basis for root-cause analysis for the problem

Based on the above-mentioned considerations, it is deemed necessary to refocus the scope of this Standard on the criteria for evaluating/testing the RF power-supply side of the RF power-delivery subsystems (i.e., the generator, cable assemblies, matching network).
It is also deemed necessary to improve the clarity of the objective, boundary conditions, and applicability of each evaluating/testing criterion in order to increase the usability of the Standard.



b. Estimate effect on industry.
1: Major effect on entire industry or on multiple important industry sectors - identify the relevant sectors
Sector or Company Information: Semiconductor-manufacturing and similar industry sectors that use RF power for plasma processing

c. Estimate technical difficulty of the activity.
II: Some Difficulty - Disagreements on known requirements exist but developing consensus is possible

2. Scope:
a: Describe the technical areas to be covered or addressed by this Document development activity. For Subordinate Standards, list common concepts or criteria that the Subordinate Standard inherits from the Primary Standard, as well as differences from the Primary Standard:
l Refocusing scope: to provide criteria for evaluating/testing the RF power-supply side of the RF power-delivery subsystems (i.e., the generator, cable assemblies, matching network)
l Resolve inconsistencies in terminology (e.g., “RF power-delivery system” is used in many locations including the title, but is not defined, while ‘RF system’ is defined but not used except in the scope).
l Resolving inconsistencies with other Standards in the “RF Standards Suite”: While E135 addresses pulsed-power RF systems, they are excluded in E113. As the use of pulsed-power RF systems in plasma-processing equipment becomes more common, this limitation should be eliminated.
l Referencing RF power measurement completely to E136 so that adaptation to newer measurement technology is possible without revising this Standard in future.
Clarification of each measurement objective, conditions, etc.

5. Safety Considerations:
The resulting document is expected:
NOT to be a Safety Guideline

NOTE FOR "to be a Safety Guideline": When all safety-related information is removed from the Document, the Document is NOT technically sound and complete - Refer to Section 15.1 of the Regulations for special procedures to be followed.

NOTE FOR "NOT to be a Safety Guideline": When all safety-related information is removed from the Document, the Document is still technically sound and complete.
