Silicon used in making chips must be very pure because if it is not, the chip will not work.

Is silicon dioxide a mixture or pure substance?
Silicon dioxide is a substance (chemical compound) consisting of one silicon atom and two oxygen atoms.
Why you do not take pure silicon and use extrinsic silicon material?
Extrinsic silicon is just silicon that has been doped. So it has different semiconducting propeties from pure (intrinsic) silicon. Why anyone needed to introduce the words intrinsic and extrinsic into the subject always baffled me.
Explain why arsenic-doped silicon conducts electric current better than pure silicon?
Pure silicon is intrinsic. It has a high resitivity which means it is a poor conductor of electricity in this state. The dopant that is introduced during the doping process can be arsenic, boron or phosphorous. These are the traditional choices to dope the intrinsically pure silicon. After the pure silicon becomes doped its electrical properties change. The main change is it has a lower resistivity and will conduct electricity. This is why silicon is called a semiconductor.
How can you make aluminum-silicon eutectic alloy?
by melting the pure alumnuim at 750c then add the pure powder silicon (12.6 wt%) to it with contineous stirring.
What are the uses of silicon tetrachloride?
silicon tetrachloride is used1-To obtained pure silicon which is used as semiconductor2-In the formation of photo voltaic cell.Answered by;Asim MukhtarU.E.T. LAHORE
Is pure silicon an insulator?
Pure silicon is a semiconductor.
Why silicon is a pure substance?
silicon is a pure substance because it is an element and as we know an element is a pure substance
What is the form of silicon?
In pure form Silicon is a solid.
Is silicon dioxide a mixture or pure substance?
Silicon dioxide is a substance (chemical compound) consisting of one silicon atom and two oxygen atoms.
What is the colour of silicon?
Pure silicon is gray in color and has a metallic luster
What are pure semiconductors?
silicon and germanium
Can clear silicon be painted?
Yes but if it is pure silicon then the paint wont stick to it.
Why is the electrical conductivity of pure silicon very low?
Because only about one from million atoms has a free electron
How Significant is the Role of Doping in Semiconductor's Conductivity?
Very. Doping determines the conductivity, pure silicon is a good insulator.
Why you do not take pure silicon and use extrinsic silicon material?
Extrinsic silicon is just silicon that has been doped. So it has different semiconducting propeties from pure (intrinsic) silicon. Why anyone needed to introduce the words intrinsic and extrinsic into the subject always baffled me.
Why we not use pure silicon instead of intrinsic silicon?
Intrinsic means no dopants. (a term used in semiconductors) So it means the same as pure.
Explain why arsenic-doped silicon conducts electric current better than pure silicon?
