New model for assessing the effect of ionizing radiation on microelectronic devices

07.12. 2018 Semiconductor Technology News - Semiconductor News, Semiconductors, Semiconductor Technology

The main trend in the development of hardware components for digital and analog electronic equipment is to reduce the size of the active regions of diode and transistor structures. This can be achieved by improving the performance characteristics of micro- and nanoelectronics devices (increasing their speed and memory, increasing operating frequencies and power, noise reduction, etc.) while keeping production costs at the same level or even reducing them. Similar processes (with a certain time lag) also take place in the development of specialized hardware elements designed for use in space systems.

Keeping up with Moore’s Law

06.12. 2018 Semiconductor Technology News - Semiconductor News, Semiconductors, Semiconductor Technology

These days, Moore's Law is not so much a scientific law as an aspiration. The notion that there is a doubling every year of the number of components that can be squeezed on to the same area of integrated circuitry was first observed in the mid-1960s by Gordon Moore, the co-founder of Fairchild Semiconductor and Intel. Ever since the microelectronics industry has strived to Moore's Law although in some periods that annual doubling seems to occur over a period of 18 months if not longer.

Imec reports for the first time direct growth of 2-D materials on 300mm wafers

03.12. 2018 Semiconductor Technology News - Semiconductor News, Semiconductors, Semiconductor Technology

This week, at the 2018 IEEE International Electron Devices Meeting (IEDM), imec, the world-leading research and innovation hub in nanoelectronics and digital technologies, presents a 300mm-wafer platform for MOSFET devices with 2-D materials. 2-D materials could provide the path towards extreme device-dimension scaling as they are atomically precise and suffer little from short channel effects. Other possible applications of 2-D materials could come from using them as switches in the BEOL, which puts an upper limit on the allowed temperature budget in the integration flow.

Controlling the crystal size of organic semiconductors

30.10. 2018 Semiconductor Technology News - Semiconductor News, Semiconductors, Semiconductor Technology

Recently, solution-processable organic semiconductors are being highlighted for their potential application in printed electronics, becoming a feasible technique to fabricate large-area flexible thin film at a low cost. The field-effect mobility of small-molecule organic semiconductors is dependent on the crystallinity, crystal orientation, and crystal size. A variety of solution-based coating techniques, such as ink-jet printing, dip-coating, and solution shearing have been developed to control the crystallinity and crystal orientation, but a method for developing techniques to increase the crystal size of organic semiconductors is still needed.

Screen-printed, large-area nPERT solar cells surpass 23 percent efficiency

24.09. 2018 Semiconductor Technology News - Semiconductor News, Semiconductors, Semiconductor Technology

At today's EU PVSEC conference, imec—the world-leading research and innovation hub in nanoelectronics, energy and digital technology and partner in EnergyVille—announced that its latest generation of large-area monofacial screen-printed rear-emitter nPERT cells feature a conversion efficiency of 23.03 percent, certified by Fraunhofer ISE CalLab. The nPERT (n-type Passivated Emitter and Rear Totally diffused) solar cells are made using an industry-compatible screen-printing process that has been designed as an upgrade of conventional pPERC (p-type Passivated Emitter and Rear Cell) processes. According to imec, its nPERT technology is projected to reach 23.5 percent efficiency by the end of this year, and there is a clear technology roadmap to eventually surpass 24 percent.
