LeddarTech selects TowerJazz’s 0.18um CIS SPAD technology for its next generation automotive LiDARs

Integration of CMOS, CIS and SPAD on the same chip saves silicon and cost, while providing high performance for autonomous driving and ADAS customers. TowerJazz, the global specialty foundry player, and LeddarTech, an industry player in the development of the most versatile and easy-to-use automotive LiDAR development platform, announced TowerJazz’s 0.18um CMOS Image Sensor (CIS) SPAD (single-photon avalanche diode) process has been chosen by LeddarTech for its next generation automotive LiDAR solutions, combining CMOS, image sensors and SPAD on the same chip.

TowerJazz’s process offers best-in-class figures of merit – high PDE, low DCR (even at elevated temperatures), and very low jitter, making it the best embedded SPAD in the world.

TowerJazz’s 0.18um CIS SPAD platform offers an integrated solution with superb figures of merit. Its photon detection efficiency (PDE) is similar to, or better than, the stand-alone SPADs in the market. The dark count rate (DCR) is less than 100Hz/um^2 at 60°C and less than 1KHz/um^2 at 100°C (especially suited for automotive applications), and jitter of less than one nanosecond. This sophisticated platform also saves silicon, and therefore, reduces cost of mass production.

LeddarTech’s LiDAR solutions enable active safety systems and semi-autonomous capabilities in vehicles, paving the way toward fully autonomous driving. LiDAR (Light Detection and Ranging), a detection system which works on the principle of radar, but uses light from a laser, is considered a must have for autonomous driving due to its high resolution at long distances. IHS Markit estimates the automotive LiDAR semiconductor market will reach $1.8 billion by 2026, with 37% CAGR (2018-2026). LeddarTech’s SoCs can be produced by Tier-1 vendors in high volumes at very competitive prices to supply OEMs with a LiDAR system tailored to their specific requirements.

TowerJazz is addressing the rapid expansion of automotive semiconductor content needed to meet the requirements of ADAS and autonomous driving through best-in-class technology solutions developed through close partnerships and roadmap alignment with market player and world-class global customer service. TowerJazz has qualified each major process flow in at least two geographically distinct production sites to ensure customers with supply and capacity flexibility at all times.

We chose TowerJazz for their deep technical knowledge, high level of flexibility, customization capabilities and the best embedded technology. Our close interaction with TowerJazz enables us to more quickly bring to market our LiDAR platform, offering a unique value proposition for Tier-1 manufacturers looking to develop a differentiated, compelling automotive LiDAR offering,” said Frantz Saintellemy, President and COO of LeddarTech.

With our advanced CIS SPAD technology, we are able to provide groundbreaking manufacturing solutions for the growing LiDAR and automotive markets. We are pleased to work with LeddarTech, a true innovator in solid state-LiDAR technology,” said Dr. Avi Strum, TowerJazz Sr. Vice President and GM, CMOS Image Sensor Business Unit.

LeddarTech’s President and COO, Mr. Frantz Saintellemy, will be presenting, “Market Forces Driving the Future of Autonomous Driving and ADAS” at TowerJazz’s US Technical Global Symposium (TGS) on November 7, 2018 in San Jose, CA.
