MS Program in Microelectronic Engineering
The objective of the master of science program is to provide an opportunity for students to perform a graduate level research as they prepare for entry into the semiconductor industry or a Ph.D. program. The program requires strong preparation in the area of microelectronics, takes two years to complete and requires a thesis.
The prerequisites include a BS in engineering (such as electrical or microelectronic engineering), including an introductory course in device physics and an introductory course in fabrication technology. Students from RIT's BS in microelectronic engineering will meet these prerequisites. Students who do not have these prerequisites can take these courses during their first quarter of study at RIT and still complete the master of science program in two years. The prerequisite courses will not count toward the 36 credits worth of graduate courses required for the MS degree.
The program consists of eight graduate level (700 level or higher) courses, including seven core courses and one elective course for students with BS degree in a discipline other than Microelectronic Engineering. Five core course and three elective courses are required for students with BS in Microelectronic Engineering. In addition, all graduate students in this program are required to take a variable-credit (1 or 0 credits) seminar/research course each quarter that they are at RIT. Up to 4 credits will be allowed to count toward the required 36 hours. A nine-credit thesis that includes dissertation submission and oral defense will be required of all students in this program. The total number of credits needed for the master of science in microelectronics engineering is 45.
* 731 cannot be taken for graduate degree credit by students with a BS in Microelectronic Engineering
The following elective courses are offered by the department of microelectronic engineering for graduate credits:
Based on the student's particular needs, he or she may, with the department approval, choose electives from other programs in the institute
Applicants must hold a baccalaureate degree in electrical, chemical engineering, materials science and engineering, physics or the equivalent, from an accredited college or university in good academic standing. An undergraduate grade point average of 3.0 or better on a 4.0 scale or strong academic / supervisor endorsements are required. Graduate Record Exam (GRE) scores are not mandatory but may support the candidacy.
Plan of study
The student in consultation with his or her advisor formulates a plan of study based on the student's academic background, program objectives, degree requirements and course offerings and submit it to the department office within the first year. If necessary, the plan of study may be requested for revision with the recommendation of the advisor.
Assistantships and fellowships
A limited number of assistantships and fellowships may be available for full-time students. Appointment as a teaching assistant carries a 12-hour-per-week commitment to a teaching function and permits a student to take graduate work at the rate of 12 credits per quarter. Appointment as a research assistant also permits taking up to 12 credits per quarter while the remaining time is devoted to the research effort, which often serves as a thesis subject. Students in the MS program are eligible for research fellowships. Appointments provide full or partial tuition and stipend. Applicants for financial aid should write directly to the department head for details.
