STMicroelectronics and MACOM RF Gallium-Nitride-on-Silicon prototypes achieve technology and performance milestones


  • Units fulfill price tag and overall performance targets and move exertion to qualification phase
  • Demonstrates sturdy development for resilient volume producing and offer

STMicroelectronics (“ST”) (NYSE: STM), a world semiconductor chief serving shoppers throughout the spectrum of electronics purposes, and MACOM Technology Solutions Holdings Inc. (“MACOM”) (NASDAQ: MTSI), a main supplier of semiconductor items for the Telecommunications, Industrial and Defense and Datacenter industries, have announced the successful manufacturing of radio-frequency Gallium-Nitride-on Silicon (RF GaN-on-Si) prototypes. With this accomplishment, ST and MACOM will continue to do the job jointly and greatly enhance our romance.

RF GaN-on-Silicon delivers substantial probable for 5G and 6G infrastructure. The prolonged-term incumbent RF power engineering, laterally-diffused metal-oxide semiconductor (LDMOS), dominated early-technology RF electric power amplifiers (PAs). GaN can give top-quality RF traits and noticeably larger output electricity than LDMOS for these RF PAs. Further, it can be created on either silicon or silicon-carbide (SiC) wafers. RF GaN-on-SiC can be much more high-priced mainly because of the competitors for SiC wafers from substantial-electric power purposes and since of its non-mainstream semiconductor processing. On the other hand, the GaN-on-Si know-how beneath improvement by ST and MACOM is expected to present aggressive overall performance paired with big economies of scale, enabled by its integration into typical semiconductor approach flows.

Prototype wafers and equipment produced by ST have obtained value and overall performance targets that would allow them to efficiently contend with the incumbent LDMOS and GaN-on-SiC systems on the sector. These prototypes are now shifting to the subsequent significant milestones – qualification and industrialization. ST is on concentrate on to hit these milestones in 2022. With this development, ST and MACOM have begun discussions to even more grow their attempts to accelerate supply of highly developed RF GaN-on-Si merchandise to the industry.

“We think that the engineering has now achieved effectiveness amounts and process maturity where by it can successfully problem the recognized LDMOS and GaN-on-SiC and we can offer you attractive price tag and supply-chain pros for higher-quantity apps, together with Wi-fi Infrastructure,” reported Edoardo Merli, Energy Transistor Sub-Group Standard Supervisor and Executive Vice President of STMicroelectronics. “Commercializing RF GaN-on-Silicon merchandise are the upcoming major milestone in our collaboration with MACOM and with ongoing progress, we appear forward to completely noticing the prospective of this fascinating technologies.”

“Together, we proceed to make great progress in shifting the GaN-on-Si technology towards commercialization and substantial-quantity creation,” said Stephen G. Daly, MACOM President and CEO. “Our collaboration with ST is an important section of our RF Electrical power technique and I am confident that we can gain sector share in qualified purposes the place the GaN-on-Silicon technologies fulfills the technological prerequisites.”


MACOM types and manufactures high-effectiveness semiconductor merchandise for the Telecommunications, Industrial and Defense and Datacenter industries. MACOM products and services around 6,000 clients yearly with a broad product portfolio that incorporates RF, Microwave, Analog and Combined Signal and Optical semiconductor systems. MACOM has achieved certification to the IATF16949 automotive standard, the ISO9001 international high quality standard and the ISO14001 environmental management conventional. MACOM operates facilities across the United States, Europe, Asia and is headquartered in Lowell, Massachusetts.

Unique Take note Relating to Ahead-Hunting Statements

This push release has forward-hunting statements dependent on ST and/or MACOM management’s beliefs and assumptions and on details at present out there to each company’s respective management. These ahead-searching statements include, amid other folks, statements about each individual company’s skill to advance its GaN-on-Silicon solutions to commercialization and higher-volume manufacturing and their ability to acquire sector share with these merchandise. These forward-searching statements replicate ST’s and/or MACOM’s present-day sights about long run events and are subject to challenges, uncertainties, assumptions and variations in situations that may trigger people events or our true routines or effects to vary materially from individuals indicated by any forward-wanting statement. Even though ST and MACOM imagine the anticipations mirrored in the ahead-hunting statements are reasonable, each company are not able to and does not promise upcoming situations, outcomes, steps, levels of action, performance or achievements. Readers are cautioned not to put undue reliance on these forward-looking statements. A amount of essential variables could cause precise effects to vary materially from people indicated by the forward-searching statements, like, but not confined to, people elements explained in ST’s hottest Variety 20-F or in “Possibility Elements” in MACOM’s Once-a-year Report on Kind 10-K, Quarterly Stories on Sort 10-Q and other filings with the Securities and Exchange Commission. Neither celebration undertakes any obligation to publicly update or revise any ahead-wanting assertion, whether or not as a result of new facts, future occasions, or if not.
