While our attention is mostly directed towards ever smaller-integrated silicon circuits providing faster and faster computing, thereâs another area of integrated electronics that operates at a much lower speed which we should be following. Thin-film flexible circuitry will provide novel ways to place electronics where a bulky or expensive circuit board with traditional components might be too expensive or inappropriate, and Wikichip is here to remind us of a Leuven university team whoâve created what is claimed to be the fastest thin-film flexible microprocessor yet. Some of you might find it familiar, itâs our old friend the 6502.
The choice of an archaic 8-bit processor might seem a strange one, but we can see the publicity advantage â after all, youâre reading about it here because of it being a 6502. Plus thereâs the advantage of it being a relatively simple and well-understood architecture. Itâs no match for the MHz clock speeds of the original with an upper limit of 71.4 kHz, but performance is not the most significant feature of flexible electronics. The production technology isnât quite ready for the mainstream so weâre unlikely to be featuring flexible Commodore 64s any time soon, but the achievement is the impressive feat of a working thin-film flexible microprocessor.
Meanwhile, if youâre curious about the 6,502, we took a look at the life of its designer, [Chuck Peddle].
We have all had the experience of one of our electronic devices overheating. Needless, to say that when that happens, it becomes dangerous both for the device and its surroundings. But considering the speed at which devices work, is overheating avoidable?
A 740 percent increase in power per unit.
Researchers at the University of Illinois at Urbana-Champaign (UIUC) and the University of California, Berkeley (UC Berkeley) have recently devised an invention that could cool down electronics more efficiently than other alternative solutions and enable a 740 percent increase in power per unit, according to a press release by the institutions published Thursday.
Imec plots a course to 1nm chips, and beyond.
Imec, the most advanced semiconductor research firm in the world, recently shared its sub-â1nmâ silicon and transistor roadmap at its Future Summit event in Antwerp, Belgium. The roadmap gives us a rough idea of the timelines through 2036 for the next major process nodes and transistor architectures the company will research and develop in its labs in cooperation with industry giants, like TSMC, Intel, Samsung, and ASML, among many others.
The roadmap includes breakthrough transistor designs that evolve from the standard FinFET transistors that will last until 3nm, to new Gate All Around (GAA) nanosheets and forksheet designs at 2nm and A7 (seven angstroms), respectively, followed by breakthrough designs like CFETs and atomic channels at A5 and A2. As a reminder, ten Angstroms are equal to 1nm, so Imecâs roadmap encompasses sub-â1nmâ process nodes.
You might not have heard of the Interuniversity Microelectronics Centre (imec) before, but it ranks among the most important companies in the world, alongside better-known companies like TSMC and EUV-toolmaker ASML. Think of imec as a silicon Switzerland, of sorts. While the semiconductor research-focused imec doesnât operate with much fanfare, it serves as the quiet cornerstone of the semiconductor industry, bringing fierce rivals like Intel, TSMC, and Samsung together with chip toolmakers such as ASML and Applied Materials, not to mention the equally-critical semiconductor software design companies (EDA) like Cadence and Synopsys, in a non-competitive environment. This collaboration allows the companies to work together to define the next generation of tools and software they will use to design and manufacture the chips that power the world.

Our electronics can no longer shrink and are on the verge of overheating. But in a new discovery from the University of Copenhagen, researchers have uncovered a fundamental property of magnetism, which may become relevant for the development of a new generation of more powerful and less hot computers.
Virginia Tech researchers are exploring quantum applications to improve communications systems, bring new methods for securing data, make devices more energy efficient, and make computers smaller.
