Computer Chips Made of Wood Promise Greener Electronics
alphadogg writes: Researchers in the U.S. and China have developed semiconductor chips that are almost entirely made out of a wood-derived material. In addition to being biodegradable, the cost of production is much less than conventional semiconductors. According to the NetworkWorld report: "The researchers used a cellulose material for the substrate of the chip, which is the part that supports the active semiconductor layer. Taken from cellulose, a naturally abundant substance used to make paper, cellulose nanofibril (CNF) is a flexible, transparent and sturdy material with suitable electrical properties. That makes CNF better than alternative chip designs using natural materials such as paper and silk, they argue in a paper published in the journal Nature Communications."
And it specializes in Bamboolean operations...
Pretending this is my office full of bitter coworkers..
but, you already knew that.
If the computer has wood.
My ism, it's full of beliefs.
So they replace the substrate with wood ... instead of silica ... the argument being that wood is plentiful and biodegradable and biologically safe ...
Except ... Silica is more plentiful and more biologically safe since its essentially biologically inert.
As an advantage, silica is NOT biodegradable, because I want my chips to last, not fall apart over the winter when it sheds its leaves.
Silica is NOT the issue for the environment in CPUs, its the production materials and doping agents that are horrible on living things and hard to dispose of.
So congrats ... you solved a problem ... wait, no, you didn't really do anything productive. Not seeing any redeeming quality about a chip produced this way and seeing plenty of down sides.
Whats next, you're going to try and convince me that the aircraft carrier made of sawdust and ice they tried to construct during WWII really was a brilliant plant for a warship sailing in the south pacific?

since global ore reserves of current substrates such as silicon and aluminum dioxide are rare and almost depleted.
Another advantage of cellulose based wafers is that using traditional Japanese technology, they can be made even smaller, and in pretty shapes like swans.
Next time they tell you that you'll set your computer on fire if you overclock, you better believe them.
So, when I say my program has a bug, I mean there is a Japanese beetle in the chip.
Thank God for computers!!! We no longer use as much paper. At least now we have a justification to keep killing trees!
Civilisation gets eaten by a fungus.
Now if they can just replace solder and thermal paste with duct tape and concrete patch....

They cut down a tree to make a chip that degrades over time so you have to buy another one. The eco-friendliness is very apparent.
So... would a foundry based on this tech... be a "wood-chipper"?
A Beowulf shrubbery of these!

So, just don't let termites get into your computer gear or what you will have is a nice pile of saw dust!
All termite jokes aside, this could have applications where disposability is a criterion. Those animated greeting cards could now be more annoying than ever before.
Also provides an useful indicator whether your overclocked rig is running too hot!
Most ACs are not even worth the keystrokes to insult them. Be generically insulted by this and ignored otherwise.
...a fungus that can grow in an environment full of As.
Pine FTW!
gives a whole new meaning to the phrase bit rot
Bugs. Bugs eat cellulose.
Thus you need to consider more than one little bit, which is the easiest bit, of the long chain of effort between sand and CPU or the new material and CPU.
As for the biodegradable rant - it's not cellulose anymore and may be no more biodegradable than many plastics.
The above assumes you are being honest and are merely mistaken.
However I suspect such an embarrassing major error was actually intentional and pretended shock jock contagious stupidity in the hope of fooling people to reject something out of hand just because "green" was in the summary and thus it needs to be put down immediately for ideological reasons. If that's the case I suggest you grow up, pull your head in, and consider it in practical terms instead of fucking stupid political games.

I don't care if it's 90,000 hectares. That lake was not my doing.
I read the title and was immediately "No."
Seriously, news like these are not news and misleading titles and vague speculation does not make it any more credible.
a semiconductor chip made out of wood. I wasn't about to repeat the same mistake when I purchased that semiconductor chip made of straw.
but what if I want to put my smartphone in the paper-shredder when I'm done with it? [when Apple releases a new model]

I'm very sorry our syrup powered wood chips, as reported in /., were not publicized sooner.

An equally valid statement.

Different kinds of trees grow at different rate
If they are really interested in creating carbon sink, they should plant more hemp, or at least, trees that grow very fast
I will give you two links that list trees that grow really fast, thus, better carbon sink

So does it turn into rocket fuel when it catches fire and you blow a high powered fan on it?
Because they were so reliable first time around.

I have a yard full of woods chips, what's the big deal?
Wood, and cellulose, are good insulators... of heat, as well. How ya gonna cool the chips? Put layers of cooling tubes through the chips?
mark "man that wood-chip is really burning... I mean, *really* burning.
Si isn't exactly toxic for rare... You'd think they would play up the flexible and transparent instead of the biodegradable.

Hope you don't have termites.
when you add a layer graphene using a specialized, hand-held instrument.
That's the one thing I can't get past, and it's a deal-killer.
How is this different from other designs that use different substrate material than used in active layer? It is just prepreg epoxy paper with thin silicon or GaAs layer on rather than using silicon/GaAs for substrate as well and this has been looked at for some time. Full article even admits paper is one of the materials used in such designs previously and this seems more of the same but they are making it sound new calling it wood. It isn't wood because there is no lignin, hence alpha cellulose papers are called "wood free" papers.
They may have tweaked the design a little by changing the type of paper but this isn't some amazing breakthrough that turns IC design upside down the way they make out, also bashing GaAs as nasty implying this doesn't have it in because hey it is wholesome "gree" tech from trees when it will still have GaAs layer in all the same unless silicon is prefered as it is in many cases in which case moot point. About as new as changing the structural materials in FR4 for PCB construction from epoxy prepreg'd E-glass to paper (or both in CEMs) only they don't BS about making some eco friendly new way to mount circuits when they do that.
Sounds like the next big leap in planned obsolescence.
