Microelectronics Device
Characterization
• Measurement of DC current-voltage
characteristics of microelectronics devices (and
small circuits)
• Used in three different courses at MIT:
• 6.002 Circuits and Electronics
• 2nd year mandatory core subject, EECS
• 6.012 Electronic Devices and Circuits
• 3rd year “header” subject, EECS
• 6.720J/3.43J Integrated Microelectronic Devices and
Circuits
• Graduate subject, EECS+DMSE
Typical Assignment:
Microelectronic Device Characterization

Extract device parameters
Construct model based on theory presented in class
Compare with measurements, discuss
Freely explore other modes of operation…
Typical Assignment
Transistor characterization project:
ƒ Measure transistor characteristics
ƒ Extract transistor parameters
ƒ Compare measurements with class models
ƒ Also, do whatever else you want with the transistor…

Need robust system capable of handling peak load
•
Need to be flexible to accommodate problems in the last night`
Is the opportunity leveraged?
