GF Delivering 45RFSOI Customer Prototypes for 5G


GlobalFoundries’ 45nm RF-SOI platform is qualified and ready for volume production on 300mm wafers (read the company’s full press release here).  It was just at the beginning of last year that GF announced the PDK availability for 45RFSOI (we covered it here).  Now there are several customers engaged for this advanced RF SOI process, which is targeted for 5G mmWave front-end module (FEM) applications, including smartphones and next-generation mmWave beamforming systems in future base stations.

In case you missed it, at the Consortium’s Shanghai symposium GF’s Mr. RF — Peter Rabbeni — gave a great talk on the company’s RF-SOI capabilities, which are very impressive (they’ve shipped over 32 billion RF-SOI devices, after all). His slides from that day are available here on the SOI Consortium website. See his slide 12 for an indication of how 45RFSOI fits into the overall picture.

As they explain it, next-generation systems are moving to frequencies above 24GHz, so higher performance RF silicon solutions are required to exploit the large available bandwidth in the mmWave spectrum. GF’s 45RFSOI platform is optimized for beam forming FEMs, with features that improve RF performance through combining high-frequency transistors, high-resistivity SOI substrates and ultra-thick copper wiring. Moreover, the SOI technology enables easy integration of power amplifiers, switches, LNAs, phase shifters, up/down converters and VCO/PLLs that lowers cost, size and power compared to competing technologies targeting tomorrow’s multi-gigabit-per-second communication systems, including internet broadband satellite, smartphones and 5G infrastructure.

Psemi and Anokiwave are among those companies at the forefront of 45RFSOI use.  Citing the drive to deliver faster, higher-quality video, and multimedia content and services Anokiwave CEO Bob Donahue said, “GF’s RF SOI technology leadership and 45RFSOI platform enables Anokiwave to develop differentiated solutions designed to operate between the mmWave and sub-6GHz frequency band for high-speed wireless communications and networks.”

The production line is in East Fishkill, N.Y.
