Imec has demonstrated the selective area growth of high-quality InP layers on 200mm Si(001) wafers. Key to avoiding the typically formed and unwanted antiphase boundaries (APBs) is the creation of atomic steps on a thin Ge buffer layer. This result is a major step forward towards the fabrication of high-performance Ge/III-V CMOS devices and the integration of optoelectronic devices on a Si chip.
The joint European project SEAL (Semiconductor Equipment Assessment Leveraging Innovation), dedicated to foster the European semiconductor equipment industry in a global market has been successfully started.
Researchers from imec and the University of Michigan have reported a new technology to fabricate complex three-dimensional microstructures, with intricate bends, twists, and multidirectional textures, starting from vertically aligned carbon nanotubes.
Imec has derived a process flow concept for the packaging of medical implants that meets the requirements for miniaturization, biocompatibility and safety. The proposed solution is a promising alternative for the currently used rigid packages that tend to enhance foreign body reactions.
Imec and Holst Centre have developed an innovative sensor for measuring ultra-low concentrations of NO2. Such sensors are important for applications that monitor environmental pollution resulting from traffic, and in general, from all combustion motors. The sensor's active components are arrays of grown vertical InAs nanowires.
At IEDM 2010, imec and its partners presented a study of the stress-induced impact of through-silicon via (TSV) processing on the performance of high-k/metal-gate CMOS transistors and circuits. This study is a first of its kind; the results and the approach that was followed are a foundation for stress-aware design with dedicated design rules. This will allow to precisely delineate keep-out zones, and thus to save valuable silicon area.
Researchers at Eindhoven University of Technology and the COBRA research institute in Eindhoven have succeeded in causing electron transport using an electronic 'ratchet'. This is the first time that usable powers have been generated at room temperature with a device of this kind. The finding opens the possibility of a new kind of wireless drive for microelectronic circuits.
Researchers at Brown University and in Korea have described the dynamics behind cutting single-walled carbon nanotubes, cylindrical structures just 1/50,000th the width of a human hair. The tubes are compressed by potent sonic booms, causing them to buckle at certain points at helical, 90-degree angles. The finding could lead to better-quality nanotubes for potential use in automotive, electronics, optics and other fields.
Scientists at the Institute of Bioengineering and Nanotechnology (IBN), the world's first bioengineering and nanotechnology research institute, have developed the first injectable hydrogel system with variable stiffness that can control cell proliferation and differentiation in a two-dimensional (2D) and three-dimensional (3D) cell culture environment.
The standard approach to cancer therapy today is to mix and match chemotherapy drugs in order to attack tumors in multiple ways. Now, two separate teams of investigators have demonstrated that using nanoparticles to deliver multiple drugs simultaneously can produce a synergistic effect that boosts the cell-killing ability of both drugs.
Researchers at Rice University, collaborating with investigators at the Baylor College of Medicine, have used two different types of imaging technologies to track the delivery of a therapeutic nanoparticle to breast tumors.
Researchers at the University of Illinois, Urbana-Champaign, have developed a new kind of microsensor to answer one of the weightiest questions in biology - the relationship between cell mass and growth rate.
