Oki will keep its memory-chip operation in business to supply system LSIs -- chips packing several functions on one silicon wafer.
Memory chip and silicon wafer stocks are trading higher on the news.
FORBES: Memory Chip Prices Spike After Quake On Tighter Supplies
Making flexible circuitry is difficult because logic circuits are traditionally made of transistors etched into a crystalline silicon wafer, which is rigid.
Semiconductor suppliers and silicon wafer makers had been among the worst hit.
FORBES: Japan Industrial Production Skyrockets As Global Supply Chain Comes Back On-Line
Two years ago, Otellini handed Jobs a pristine silicon wafer to mark the announcement of the first Intel-powered Apple portable computer, the MacBook Pro.
The sheer size and diversity of the chip market will allow more than one winner, but margins will be as thin as a silicon wafer.
The site says that the main silicon wafer plant operated by Shin-Etsu Handotai , in Skirikawa, has shut down due to a lack of electricity.
FORBES: Memory Chip Prices Spike After Quake On Tighter Supplies
Shares of silicon wafer producer MEMC Electronic Materials slumped in late trading Wednesday, after the company reduced its profit outlook for the full year.
In a process similar to printing a photograph, engineers beam high-powered light through a mask-like image of the chip, creating a duplicate on a silicon wafer.
In a process similar to printing a photograph, engineers beam high-powered light through a masklike image of the chip, thus creating a duplicate on a silicon wafer.
If Proteus is right, and these sensors become commonplace, exponential growth in digital medicine for compliance monitoring will require as much silicon wafer manufacturing as all computer chips use today.
Light particles blast the photosensitive material on a silicon wafer to create the features on a chip, just as in photography, photons transform silver molecules on photographic film into visible images.
The balance spring is etched out of a thin silicon wafer using a photolithographic technique, similar to that used for microelectronic chips, so its exact shape and thickness can be more carefully controlled than with metal.
ECONOMIST: A luxury watchmaker is putting silicon in its timepieces
For any given good, be it a metal lathe or a silicon-wafer saw, most potential buyers will not have access to a physical auction.
Under current manufacturing techniques, manufacturers take their sapphire or silicon carbide wafer and chop, or cut it into individual chips, which get tested and packaged.
FORBES: How Silicon Will Spur A Boom In Solid-State Lighting
But they do not react with the silicon when the wafer is heated.
By switching from sapphire to silicon wafers, the wafer size jumps from two or four inches to eight inches.
FORBES: How Silicon Will Spur A Boom In Solid-State Lighting
Instead of using light to etch a transistor circuit on a wafer of silicon, they propose to fabricate tiny wires.
Semiconductors are manufactured on silicon wafers and the cost of a processed wafer is about the same no matter what you build on it.
As the pressure builds up in these bubbles, they expand and rip the thin layer of silicon above them away from the rest of the wafer.
We get more wafers out of our great big ingot of silicon and thus, if silicon stays static in price then the price of each wafer should be falling.
FORBES: Noahpinion's Two Errors About Free Trade: Yes, Unilateral Free Trade Is The Answer
The wafer is then heated and the oxygen reacts with the silicon around it, making silicon dioxide (ie, glass).
The consortium's technology builds its transistors inside a sliver of pure silicon, laid on top of an insulator, which in turn sits on top of a standard wafer, the substrate on which transistors are constructed.
This method allows better control of the thicknesses of the silicon and glass layers, but the etching is time-consuming and requires the costly sacrifice of a wafer for each one that is made.
