Vanderbilt University`s Nano-materials and Energy Devices Lab has developed an ultrathin energy harvesting system based on battery tech and layers of black phosphorous which is only a few atoms thick. The device can harvest electricity from human motion. The research director said that the method has two fundamental advantages; the materials are atomically thin and small enough to be impregnated into textiles without affecting the fabric’s look or feel and it can extract energy from movements that are slower than 10 Hertz–10 cycles per second–over the whole low-frequency window of movements corresponding to human motion. Bending the prototype devices produces as much as 40 microwatts per square foot and can sustain current generation over the full duration of movements as slow as 0.01 Hertz, one cycle every 100 seconds given that the basic building blocks of the harvester are about 1/5000th the thickness of a human hair.
With the tremendous increase in the sales of semiconductor and IC applications, the photomask market is expected to increase to nearly $5000 million dollars by 2025. Recent advancement in technology announced by Intel, Qualcomm and Nvidia show a healthy sign of growth for the photomask market, as currently 30% of the photomask is used by the manufacturing companies. In coming years, the integration of robotics is the expected trend to boost the market for photomask materials.
The group led by Dr. Christian Klinke has now succeeded in producing transistors based on a completely different principle. They use metal nanoparticles which are so small that they no longer show their metallic character under current flow but exhibit an energy gap caused by the Coulomb repulsion of the electrons among one another. Via a controlling voltage, this gap can be shifted energetically and the current can thus be switched on and off as desired. These Coulomb transistors have three main advantages: The synthesis of metal nanoparticles by colloidal chemistry is very well controllable and scalable. It provides very small nanocrystals that can be stored in solvents and are easy to process. The Langmuir-Blodgett deposition method provides high-quality monolayered films and can also be implemented on an industrial scale.
To enhance its stronghold in the SP&C(Surface Prep and Clean) technology in the growing semiconductor industry especially the rising advanced packaging material market. The Versum materials will acquire Dynaloy for approximately $13 million.
The SiP(System in Package) technology is finding widespread adoption in the semiconductor industry packaging industry. The SiP is built on existing flip chip, wafer bumping, wire bonding and fan-out wafer level packaging. Technical advances are I two-folds, one is in terms of 2.5D and other in terms of putting together myriad types of functions. These advances can be successfully adopted in wearables and IoT applications. Mobile devices, wearables and consumer applications account for 82% of SiP implementations and expected to grow annually by 13.7% till 2020. The iPhone 7 and 7 Plus smartphones each have about 15 SiPs, while the Samsung Galaxy S8 handset has 13 SiP packages.
