Vaporizing dust during chip manufacturing ?

No. To hard on the machinery when it recondenses.

That is part of the machining process. Clearing away the dross is a small part what a machinst does.

Blowing up the machine, the operator, the building it is in, and the city that supports the machine shop seems a little extreme, don't you think? A megaton nuclear weapon "converts" a few nanograms of mass to energy (the rest is there just for chance).

Lessee. Obviously you are an "idea man" rather than someone who works out the mundane details! I don't know. maybe a giant laser or nuclear reactor or perhaps an LHC would be the way to go to "smash" dust particles in chip manufacture rather than the usual fans and filters. I mean how much more could it cost?

Instead of asking questions that make you look even more stupid than we already know that you are, you should simply perform a GOOGLE SEARCH or other commonly available search engine and READ up on the topic, IDIOT!

You should also stop watching tech shows, because since you do not even have the aptitude to grasp the material discussed on them, all they serve to do is cause you to come here and gum up Usenet with absolutely retarded questions.

Do some real research for once in your life, you lazy little punk f*ck.

You are an idiot. He never said a damned thing about "machining", idiot.

chips are GROWN , and get deposits placed onto them akin to crystal growth.

You should do some google work as well. Particulalry BEFORE you make a post where you place your foot in your mouth.

Jeez, you are even more stupid than he is!

Grams? Grams of WHAT? I am sure that 46.49 grams of water would yield less than 46.49 grams of highly enriched Uranium.

Also, a nuke does not "convert a few nanograms". For one thing, it does not get "converted", it gets "released".

The first ones REQUIRED 100lbs of material to go critical.

Modern devices "need" less, but the designs are hardly set up where they include more than they need. To claim so is just stupid.

Also, ALL of it goes fissile, so the "just there for chance" remark is stupid as well.

Your brain must only weigh a few nanograms. There cannot be any more than that after stupid statements like the one you made here.

Simply blast each dust particle on the wafer surface with a same-sized chunk of antimatter.

I generously donate this invention to the public domain.

Perhaps you could dive into a pool of antimatter and get 'blasted away'.

I generously donate this Earth soothing suggestion to you. That way, you might be able to recover a tiny bit of honor.

Grams of matter converted into energy according to E = mc^2 EricP is right on the money. Nuclear binding energy is released by fission and the bits remaining afterwards weigh a little bit less. The mass difference becomes kinetic energy and electromagetic radiation.

A nanogram of mass annihilated would release about 90kJ - barely enough to boil the water needed to make a small pot of tea.

I did do a quick google for "vaporizing dust particles" before posting... it turned up nothing !

So maybe you should do what you recommend that I should do first ! ;) :)

Bye, Skybuck.

Serious lasers, like NIF, have to be very careful about dust. When they fire the laser, dust on optics can explode and blast tiny craters in the glass. I think NIF is the world's biggest clean room.

It is easier to place most of the manufactuing process in a vacuum and eliminate the dust particles. {Hint: dust cannot float in a vacuum to land on the wafers, but drops like a rock to the floor.}

Try semiconductor particulate or semiconductor contamination or things like that. "Dust" is sort of lowbrow to the people who write papers about this.

John

Which makes it obvious to me that he did not know the first thing about it.

They are not using lasers to blast away particles, idiot. It would be too easy to damage the surface it sits on.

Just ask Neil Armstrong.

Low brow is the wrong term, idiot.

Of course they are. They're just not doing it on purpose. Silicon wafers would have a similar problem: enough energy to blast dust would probably damage the wafer. E=MCsquared would damage everything nearby.
