Course Justification
All students that obtain a graduate (M.S. or Ph.D.) degree in the solid

state area should
have knowledge of (a) VLSI devic
es, (b) microwave devices, (c) optoelectronic devices, and
(d) power devices. Since m
ore than half of all the electricity used in the country is controlled
by power semiconductor devices
, this is an import topic for
future jobs on
research and
product deve
lopment
in the industry for our students
.
In addition, all
students
working on
power electronic circuits
should have a basic knowledge of the various types of power
semiconductor devices used by the industry
.

Grading
:

–
The final course grade will be determined by the weighted average of:
Six (6
) Home Work Assignments
= 20
% of total final grade
Mid

Term Exam
= 3
0% of total final grade
Final Exam
= 5
0
% of total final grade
Hom
e Work Assignments
Homework problems will be assigned from the textbook to allow practicing of the concepts
covered in the classroom. Students may consult each other to obtain the solutions but must
submit the answers individually. All intermediate steps t
aken to get the solutions should be
included. The homework number and the individual problem numbers must be clearly shown on
the submitted answers to ensure proper credit.
All HW assignments must be turned

in at the class
on the due date to get credit.
M
id

Term Exam
A mid

term exam will be administered to test the knowledge of students at the middle of the
semester
. The
mid

term exam
will be
an open

book test
. Significant credit will be given to the
method used for solving the problem. This must be demons
trated by the student by clearly
showing all the steps required to solve the problem, including the formulae used to obtain the
numerical answers.
Only
the
University approved reasons will be accepted for missing
the mid

term exam
(S
ee
http://www.ncsu.edu/
policies/academic_affairs/pols_regs/REG205.00.4.php
).
A make

up
mid

term
exam
will be administered at the mutual convenience of the student and the Instructor. In all
cases, signed documentation must be provided to the Instructor and attached to the make u
p
mid

term exam
in order to obtain credit.
Final Exam
The final exam will include all the material covered in the course. The final exam is an ‘Open
Book’ exam with access to all information (such as class notes, textbook, homework solutions,
and
mid

ter
m exam
solutions). Significant credit will be given to the method used for solving the
problem. This must be demonstrated by the student by clearly showing all the steps required to
solve the problem, including the formulae used to obtain the numerical ans
wers.
General
Makeup Policy
If serious reasons prevent a student from taking an exam on the scheduled date the opportunity to
make

up will be offered according to the official acade
mic policies
(
http://www.ncsu.edu/policies/academic_affairs/pols_regs/REG2
05.00.4.php
).
Grading Scale for Course
The following system will be used to convert your weighted average score (

) for the home

works,
mid

term exam
and final exam into a letter grade:

Academic Integrity
Work in this course is to be done under the Academic Integrity Honor Ple
dge:
"I have neither given nor received unauthorized aid on this test or assignment."
Students must abide by the Code of Student Conduct,
http://www.ncsu.edu/po
licies/student_services/student_discipline/POL11.35.1.php
Evidence of copying, including copying of source code, or any other use of unauthorized aid
will be investigated and potentially referred to the University judicial system as a violation of
the
Cod
e of Student Conduct
. The
minimum sanction
for a violation is a zero on an
assignment. Recycling of projects from another class will be considered an academic integrity
violation.
Students with disabilities
Reasonable accommodations will be made for studen
ts with verifiable disabilities. In order to
take advantage of available accommodations, students must register with Disability Services
for Students at 1900 Student Health Center, Campus Box 7509, 515

7653.
