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.)
The M71 Standard covers SOI wafers for classical/standard CMOS applications while the field of SOI based RF devices (for example: RF antenna switches for mobile devices) has developed very rapidly over the last several years. Wafers for this application space, called RFSOI wafers, have become a major area of SOI in terms of technical development as well as business volume.
Technical requirements for RFSOI are significantly different (more complex) than the SOI wafers for CMOS described in M71. Intent of this work is to create a new SEMI Standard specifically for RFSOI wafers.
b. Estimate effect on industry.
2: Major effect on an industry sector - identify the relevant sector
Sector or Company Information:
c. Estimate technical difficulty of the activity.
II: Some Difficulty - Disagreements on known requirements exist but developing consensus is possible
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:
RFSOI wafers (any wafer diameter), specifically base wafer properties (resistivity, interstitial oxygen) and any additional layers on the base wafer to improve RF performance.
b: Expected result of activity
New Standard or Safety Guideline (including replacement of an existing Standard or Safety Guideline)
For a new Subordinate Standard, identify the Primary Standard here:

6. Intellectual Property Considerations:
For a new Standard or Safety Guideline and for any part to be modified or added in a Revision of published Standards and Safety Guidelines
the use of patented technology is NOT required.
If "patented technology is intended to be included in the proposed Standard(s) or Safety Guideline(s) " is selected above, then also check one:
