Uniform Spin Qubit Devices with Tunable Coupling in an All-Silicon 300 mm Integrated Process


Abstract: Larger arrays of electron spin qubits require radical improvements in fabrication and device uniformity. Here we demonstrate excellent qubit device uniformity and tunability from 300K down to mK temperatures. This is achieved, for the first time, by integrating an overlapping polycrystalline silicon-based gate stack in an ‘all-Silicon’ and lithographically flexible 300mm flow. ... » read more

Reaching silicon-based NEMS performances with 3D printed nanomechanical resonators


Abstract: "The extreme miniaturization in NEMS resonators offers the possibility to reach an unprecedented resolution in high-performance mass sensing. These very low limits of detection are related to the combination of two factors: a small resonator mass and a high quality factor. The main drawback of NEMS is represented by the highly complex, multi-steps, and expensive fabrication process... » read more

Effect Of Environmental Factors On ADAS Sensor Performance (AAA)


Abstract "Advanced driver assistance systems (ADAS) are becoming increasingly integrated within new vehicles sold in the United States. However, the majority of publicly available performance evaluations occur within idealized operation conditions in terms of weather, time of day, and sensor status, which are typically unrepresentative of naturalistic environments.  To evaluate the performa... » read more

Get Ready For The Next Generation Of Wearable Tech


Wearables have attracted a lot of attention recently, due to both their successes as well as failures. They bring together requirements for packaging, new substrates, power scavenging, low-power, novel connectivity, flexibility, durability, as well as fashion. While some of the challenges remain formidable, the long-term potential is driving the industry to look at what is possible. They are... » read more

Bringing Scalable Power Integrity Analysis To Analog IC Designs


Power integrity is a broad term in integrated circuit (IC) design and verification. However, when IC engineers are working through design signoff, power integrity analysis focuses on three specific aspects of a design: Power: Verify the chip design as implemented provides the total predicted power under different operating modes. Performance: Find and eliminate performance issues affect... » read more

40 GHz VCO and Frequency Divider in 28 nm FD-SOI CMOS Technology for Automotive Radar Sensors


Abstract: "This paper presents a 40 GHz voltage-controlled oscillator (VCO) and frequency divider chain fabricated in STMicroelectronics 28 nm ultrathin body and box (UTBB) fully depleted silicon-on-insulator (FD-SOI) complementary metal-oxide–semiconductor (CMOS) process with eight metal layers back-end-of-line (BEOL) option. VCOs architecture is based on an LC-tank with p-type metal-oxide�... » read more

Automotive Lidar Technologies Battle It Out


Lidar is likely to be added to the list of sensors that future cars will use to help with navigation and safety, but most likely it won't be the large rotating mirror assembly on the top of vehicles. Newer solid-state radar technologies are being researched and developed, although it’s not yet clear which of these will win. “The benefits of lidar technology are well known dating back to ... » read more

Safe And Robust Machine Learning


Deploying machine learning in the real world is a lot different than developing and testing it in a lab. Quenton Hall, AI systems architect at Xilinx, examines security implications on both the inferencing and training side, the potential for disruptions to accuracy, and how accessible these models and algorithms will be when they are used at the edge and in the cloud. This involves everything ... » read more

Changes In Sensors And DSPs


Pulin Desai, group director for product marketing, management and business development at Cadence, talks about why processing is moving closer to the end point, how to save energy through reduced area and sensor fusion, and the impact of specialization, 3D capture and always-on circuits. » read more

Customizing Chips For Power And Performance


Sandro Cerato, senior vice president and CTO of the Power & Sensor Systems Business Unit at Infineon Technologies, sat down with Semiconductor Engineering to talk about fundamental shifts in chip design with the rollout of the edge, AI, and more customized solutions. What follows are excerpts of that conversation. SE: The chip market is starting to fall into three distinct buckets, the e... » read more
