Where do silicon wafers come from?
A silicon wafer is a thin slice of crystal semiconductor, such as a material made up from silicon crystal, which is circular in shape..
Why are silicon wafers so expensive?
That silicon must be refined to a purity that was not thought possible a few decades ago. These refining steps are costly. The bulk of the cost of a raw wafer (~$500) is in this process, and the capital equipment and energy used to produce it.
What is wafer made of?
Wafers are formed from flour and water dispersions (batter) with small amounts of fat, sugar, salt and sodium bicarbonate, which are mixed and then confined in preheated moulds3.
What is silicon wafer used for?
In electronics, a wafer (also called a slice or substrate) is a thin slice of semiconductor, such as a crystalline silicon (c-Si), used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells. The wafer serves as the substrate for microelectronic devices built in and upon the wafer.
What is the meaning of silicon chips?
n electronic equipment consisting of a small crystal of a silicon semiconductor fabricated to carry out a number of electronic functions in an integrated circuit. Synonyms: chip, micro chip, microchip, microprocessor chip Types: show 5 types…

Why a chip made in high volume should cost less?
With high volumes, the manufacturing process can be tuned to a particular design, increasing the yield. … It is less work to design a high-volume part than a low-volume part. 3. The masks used to make the chip are expensive, so the cost per chip is lower for higher volumes.
How much is a silicon wafer?
The minimum silicon cost with 200mm diameter wafers is about $2 per square inch, resulting in a maximum cost per wafer of $100.. The minimum silicon cost reached with 300mm diameter wafers is about $3 per square inch, resulting in a maximum cost per wafer to of $400.
Is Silicon cheap or expensive?
Silicon 99.9% pure costs about $50/lb; hyperpure silicon may cost as much as $100/oz.
Why are CPU so expensive?
The main reason is production cost. Much of the production of CPUs involves extremely expensive, highly technical and brand new machinery. You may hear different terms like 5 nano metre and 14 Nanometer.
How much does it cost to make a chip?
Koeter said at mainstream nodes—40nm to 65nm—the price of a new chip is roughly $40m to $50 if it’s from scratch. But yield is high at those nodes, and the software development cost is lower because those chips are not at the leading edge of functionality.
How much does it cost to make a processor?
How does the semiconductor giant continue to pull in the profits? By keeping costs low, says In-Stat. Though Pentium 4s can sell for up to $637, Intel’s average cost for making a chip comes to $40, according to a report from analysts In-Stat.
Why silicon is used to make chips?
Silicon is quite cheap thanks to its abundance and is not that hard to purify. … In short, that is why silicon became ideal for computer chips use. The extra small transistors in our CPUs needed insulated areas to control and direct the flow of electricity precisely.
