STMicroelectronics (Geneva, Switzerland) and Tower Semiconductor (Migdal Haemek, Israel) have announced an agreement to operate together the ST’s R3 300mm fab under construction on its Agrate Brianza site in Italy. Both companies will accelerate the ramp-up of the fab. ST and Tower will share the clean room space and the facility infrastructure, with Tower installing its own equipment in one third of the total space.

The fab is expected to be ready for equipment installation later this year and start production in the second half of 2022. Both companies will invest in their respective process equipment and work together on the acceleration of the fab qualification and subsequent ramp-up. Operations will be managed by ST, with select Tower personnel seconded to ST in specific roles to support fab’s qualification, volume ramp-up and other engineering roles. In the early stage 130, 90 and 65nm processes for smart power, analog mixed signal and RF processes will be qualified in R3.

This will enable an optimal utilization of the fab almost right from the early stage of production”, said Jean-Marc Chéry, President and CEO of STMicroelectronics. “The products manufactured in Agrate R3 will support the automotive, industrial and personal electronics markets. They will contribute to ease the supply tensions in a wide range of applications in the mid to longer term.” Tower CEO, Russell Ellwanger, said that the agreement “will more than tripling Tower’s 300mm foundry capacity.”

To implement this project, Tower will establish a wholly-owned Italian subsidiary. Tower Semiconductor provides foundry services based on customizable process platforms such as SiGe, BiCMOS, mixed-signal/CMOS, RF CMOS, CMOS image sensor, non-imaging sensors, integrated power management (BCD and 700V), and MEMS. It operates two manufacturing facilities in Israel (150mm and 200mm), two in the U.S. (200mm) and three facilities in Japan (two 200mm and one 300mm) through TPSCo. Tower’s revenues for the full year 2020 totaled $1.266 billion.

Tower Semiconductor Introduced new in-Chip Capacitors

Tower Semiconductor announced a newly developed galvanic capacitor technology integrated with its 0.18um power management and mixed signal platforms, enabling  up to 12kV isolated gate driver and digital isolator ICs. The company said that its new in-chip high capacity capacitors, enhance safety and power efficiency for applications in the automotive, green power and industrial markets, addressing an estimated $1B market.

The new technology offers a cost and size advantage thanks to the integration of the galvanic isolator, saving the need for an additional device. Lead customers are prototyping initial products addressing applications such as battery chargers, power supplies and motor drivers for electric and hybrid vehicles, solar inverters and wind turbines power converters) and industrial applications.

“This new technology supports the needs of isolated power in high-growth markets such as electrical vehicles and other,” said Shimon Greenberg, Tower’s VP and General Manager of Mixed-Signal and Power Management Division. “The new technology augments our 0.18um power technology, supporting applications from 5V to 200V”.

TowerJazz is a manufacturing services provider of integrated circuits (ICs). Its technology is comprised of SiGe, BiCMOS, mixed-signal/CMOS, RF CMOS, CMOS image sensor, integrated power management (BCD and 700V), and MEMS. TowerJazz operates two manufacturing facilities in Israel (150mm and 200mm), two in the U.S. (200mm) and three facilities in Japan (two 200mm and one 300mm).

Tower hit by cyber attack, some production disrupted

Tower Semiconductor’s IT security systems identified a security incident on some of its systems as a result of a cyber attack. The company announced that as a preventive measure, it had halted certain of its servers and proactively held operations in some of its manufacturing facilities, and has done so in a gradual, organized manner.

Tower has notified relevant authorities and is working closely with law enforcement organizations and with a team of experts, coordinated with its insurance providers, in order to recover the impacted systems as soon as possible. The Company has implemented specific measures to prevent the expansion of this event.

Tower Semiconductor provides manufacturing services for integrated circuits (ICs) in process platforms such as SiGe, BiCMOS, mixed-signal/CMOS, RF CMOS, CMOS image sensor, non-imaging sensors, integrated power management and MEMS. It operates two manufacturing facilities in Israel (150mm and 200mm), two in the U.S. (200mm), and three facilities in Japan (two 200mm and one 300mm).

In September 10, Tower announced that all of its manufacturing sites are operational, targeting full capability within the next few days. “Tower is confident of the functional quality of the work in progress and production line inventories, with Company and customer data remaining protected. Due to the manufacturing disruption, the Company expects some level of impact to its third quarter results.”

Semiconductor’s Industry under Attack

Cyber attacks pose a big risk to the highly connected semiconductor’s production lines. On May, 2020, the US-based MaxLinear discovered a security incident affecting some of its systems and immediately took all systems offline. On August, 2018, TSMC, a supplier for Apple’s SoC components and a major manufacturer for Qualcomm, fell victim to a variant of the WannaCry ransomware. The infection caused the company to stop production for two days. The shutdown was believed to have cost the company roughly $250 million USD and shipment delays.

According to the Taiwanese cyber security firm CyCraft, multiple organizations along Taiwan’s high-tech ecosystem were victims of an advanced persistent threat (APT) attack , which originated in the semiconductor industry and still continues to be a threat today. “APTs are professional cyber espionage actors that typically receive direction and support from nation-states and often target organizations with high-value information, such as national defense, financial, energy, or now, the manufacturing of semiconductors.”


Tower Semiconductor Announced ultra-fast RF Switch

Tower Semiconductor announced a new radio frequency (RF) switch technology with record figure of merit targeting the 5G and high-performance RF switch markets. The company is engaged with multiple customers and partners to bring this technology to market for next-generation products.

This new switch technology demonstrates a record RF device figure of merit: On/Off transition times (Ron Coff) shorter than 10 femtoseconds vs. 70-100 femtoseconds in use today for the most advanced applications. The switch performs over a wide range of frequencies spanning MHz to mmWave, including the frequency bands discussed for 5G.

The switch is also nonvolatile so consumes no energy when in the on-state or off-state, making it attractive for IoT, and other power and battery sensitive applications. Tower has demonstrated the versatility of this patented technology by integrating it with other process platforms such as SiGe BiCMOS and Power CMOS.

Tower Semiconductor will be offering multi-project wafer runs (MPWs) in 2021 for select customers. This model enables new customers to experience the technology in lower costs, by sharing the wafer in production with other interested parties. The new RF switch will be presented at IMS 2020 (International Microwave Symposium).

The abstract of Tower Semiconductor’s presentation in IMS 2020 reveals more details about the new technology: Two different sized layouts of four-terminal phase-change material (PCM) RF switches fabricated in a 200 mm silicon high volume manufacturing environment. Both layouts have with a record high FCO of 25 THz. Layout-A has a RON*C_OFF values of 6.2 fs, and Layout-B has a RON*C_OFF values of 6.3 fs.

Both layouts show minimal changes to RON or actuation voltage when cycled 10 million times. Also, a Layout-A device was cycled 1 billion times, demonstrating the ability of this RF switch to be used in high endurance applications.
