CASE STUDY

This assignment consists of a written report of approximately 1000 words and any diagrams in which you are asked to critically compare different process methods used to achieve the same result and show an awareness of current developments in semiconductor fabrication.

QUESTION

In the production of a CMOS gate the required doping may be achieved by thermal diffusion or by ion implantation.

Briefly describe each process and the relative advantages of each.

Identify which process is used in the various doping stages in the production of a CMOS gate.

Explain the effect upon doping methods as feature sizes in modern devices fall to well below the sub- micron feature size.

Verified Expert

This task is based on SEMICONDUCTOR STRUCTURE & FABRICATION and covered all details based on CMOS gate with word range of 1000 .

This assignment forms part of the formal assessment for this module. If you fail to reach the required standard for the assignment then you will be allowed to resubmit but a resubmission will only be eligible for a Pass grade, not a Merit or Distinction. You should therefore not submit the assignment until you are reasonably sure that you have completed it successfully. Seek your tutor's advice if unsure.
