Synthesizing and Optimizing a Hairpin Bandpass Filter with AWR Tools App Note

AWR published a new application note about the synthesis and design of complex filters. The app note uses a hairpin bandpass filter to illustrate how AWR’s iFilter synthesis software in conjunction with Microwave Office high-frequency design software and AXIEM 3D planar electromagnetic (EM) solver can help designers create filters that conform to specific manufacturing constraints and costs. The title of the paper is Synthesizing and Optimizing a Hairpin Bandpass Filter with AWR Tools.

Piezo Technology in Materials Testing Technote

PI (Physik Instrumente) published an interesting technote about using scanning probe microscopy with piezo stages and capacitive nanometrology sensors to improve nano-indentation and materials testing systems. The NanoTest from Micro Materials is ideal for use with a wide range of materials because it can apply forces of between 30 nN and 500 mN depending on the operating mode, and it can measure penetration depths of between 0.1 nm and 50 ìm. The task is carried out by a high-resolution capacitive sensor, the PISeca sensor from PI.

Micro- and Nanopatterning of Inorganic and Polymeric Substrates by Indentation Lithography

The Whitesides Group at Harvard University and CSM Instruments published an nanotech article on complex 3D-nano patterns with Indentation Lithography (IndL) and piezo technology. The paper describes the use of a nanoindenter, equipped with a diamond tip, to form patterns of indentations on planar substrates (epoxy, silicon, and SiO2). The indentations have the form of pits and furrows, whose cross-sectional profiles are determined by the shapes of the diamond indenters, and whose dimensions are determined by the applied load and hardness of the substrate.

Imec Creates Optical I/O Industrial Affiliation Program

Imec is creating a new industrial research program on high-bandwidth optical input/output (I/O). The goal of the new program is to explore the use of optical solutions for realizing high-bandwidth I/O between CMOS chips. The affiliation program is a part of imec’s research platform on deep-submicron CMOS scaling. In close collaboration with imec’s industrial partners, the optical I/O program will develop a silicon-photonics solution for addressing the upcoming scaling challenges in interconnecting CMOS chips.

Imec Research on Implant-free SiGe, 2x nm Node DRAM, and RRAM

Imec recently revealed their CMOS research in scaling logic, DRAM and non-volatile memory. A new device based on non-silicon channels was realized to scale high-performance logic towards the sub-20nm node. In addition, imec developed low-leakage capacitors enabling DRAM to be pushed to the 2x nm node. Imec also shared their research on the switching mechanism of resistive RAM for next-generation flash memories (RRAM). The results were obtained in cooperation with imec’s key partners in its core CMOS programs: Intel, Micron, Panasonic, Samsung, TSMC, Sony, Fujitsu, Infineon, Qualcomm, ST Microelectronic and Amkor.

White Paper: Cadence Design Systems Silicon Realization

Cadence Design Systems recently published a white paper on their new Silicon Realization approach. The technical paper explains how Silicon Realization is a fundamentally new approach to semiconductor design, verification, and implementation. Silicon Realization extends traditional EDA to cover both integration and creation. It unites functional, physical, and electrical concerns. It is also based on three emerging concepts: unified intent, higher abstraction levels, and convergence.
