Phosphorus is implanted into silicon. The implant parameters are a dose of 1015cm-2at an energy of 150keV. a)Find the depth of the peak of the implant profile and its value at that depth. b)If the wafer originally had 1016cm-3of boron uniformly distributed throughout, find the depth(s) at which the concentration of phosphorus is equal to the concentration of boron.

a)  ≈ 4.99 / cm^3

b)   0.515 um

Explanation:

Given data:

energy = 150 Kev

dose of 10^15 cm^-2

A) find the depth of the peak of the implant profile and its value at that depth

expression for implant profile = written below in the attached file

value of the peak depth ≈ 4.99 / cm^3

B ) determine the depth at which the concentration of phosphorus is equal concentration of boron

= 0.515 um

attached below is the detailed solution to the problem

the answer is b. dilution

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
