High-Temperature-Stable, Spin-On Carbon Materials For High-Aspect-Ratio Gap-Fill Applications


Brewer Science, Inc. has developed a class of novel, high-temperature-stable spin-on carbon (SOC)-based materials with excellent processability. These SOCs are cured under mild conditions and have flow properties that enable the fill of high-aspect-ratio vias in a void-free manner. Moreover, this new class of SOCs has remarkable thermal stability and can survive temperatures of up to 550°C wit... » read more

Replacement Gate High-k/Metal Gate nMOSFETs Using A Self-Aligned Halo-Compensated Channel Implant


A device design technique for boosting output resistance (Rout) characteristics of long-channel halo-doped nMOSFETs for replacement gate (RMG) high-k/metal gate (HK/MG) devices is proposed based on numerical simulations. We show that the self-aligned halo-compensated channel implant (HCCI) that is carried out after dummy poly gate removal provides compensation for the conventional halo doping. ... » read more

Primary, Anonymous, or What?


Top level primary I/Os remain mysterious in the verification world, specifically when you consider UPF-based low power designs. In real silicon, they are usually driven by off-chip supplies; however, verification complications are multifold for RTL and gate level simulations of them. This paper studies the “simulation-impacting” features of design top IOs and the effect of each feature on v... » read more

Accelerate Adoption Of High-Speed, Low-Latency, Cache-Coherent Standards Using Formal Verification


We continue to see huge growth in data and compute demand, fueled by increased global data traffic with the 5G rollout, the prevalence of streaming services, and expanded artificial intelligence and machine learning (AI/ML) applications. Several new industry-standard specifications have emerged in recent years to define the protocols of the underlying electronic components and IP building block... » read more

Data Center Evolution: Accelerating Computing With PCI Express 5.0


The PCI Express (PCIe) interface is the critical backbone that moves data at high bandwidth between various compute nodes such as CPUs, GPUs, FPGAs, and workload-specific accelerators. The rise of cloud-based computing and hyperscale data centers, along with high-bandwidth applications like artificial intelligence (AI) and machine learning (ML), have pushed PCIe 4 to its limits. In this white p... » read more

How To Build A Virtual Electromagnetic Test Environment For Aerospace And Automotive Platforms


To protect the electromagnetic compatibility (EMC) of complex systems like aircraft and automobiles, you need a full electromagnetic (EM) model. A virtual test environment allows you to assess a design and ensure system-level compatibility before physical testing. This process has been proven to save more than $1 million compared to an approach based solely on testing. Learn how to build a v... » read more

A Revolution For Power Conversion Systems — CoolSiC MOSFET


Silicon carbide (SiC) transistors are increasingly used in power converters, placing high demands on the size, weight and/or efficiency. The outstanding material properties of SiC enable the design of fastswitching unipolar devices as opposed to bipolar IGBT devices. Thus, solutions which have been up to now possible in the low-voltage world only (< 600 V) are now possible at higher voltages... » read more

Autonomous driving is playing a big role in the automotive industry and defines the future of mobility on a big scale. However, autonomous driving faces several challenges, such as the performance of artificial intelligence and hardware reliability. To ensure safe functionality, the reliability of the electronic components plays an essential role and must be taken into consideration. One aspect... » read more

The Emergence Of Inline Screening For High Volume Manufacturing


The semiconductor content of automobiles is growing rapidly in applications where quality is of paramount importance, and automotive manufacturers have taken the lead in driving a “Zero Defect” mentality into their supply chain. The motivation behind this paper started with engagements with semiconductor suppliers as well as automotive manufacturers, where KLA witnessed many clear examples ... » read more

Characterization Of CMP Processes With White Light Interferometry


Faster computer and electronic processors require smaller features for integrated circuits (IC), which in turn require smaller and smoother substrate surfaces. Chemical mechanical polishing (CMP) has become one of the most critical semiconductor fabrication technologies because it offers a superior means of removing unwanted topography in interlevel dielectric layers and achieving sufficient pl... » read more
