From microelectronics to making: Incorporating microelectronics in a first-year engineering course

This paper describes a half-semester module in an Introduction to Engineering course that uses microelectronics technology to introduce students to basic ECE concepts and engineering design. The module uses CMOS integrated circuit technology as a vehicle for introducing basic concepts including voltage, current, and logic levels while also providing students with perspective on how integrated circuits are designed and manufactured. It then introduces microelectronics-based technologies including computer processors, microcontrollers, and microcontroller-based “maker” tools including laser cutters and 3D printers. Concepts are reinforced through a series of hands-on lab exercises that include CMOS layout design, simple microcontroller programming with basic I/O devices including switches, LEDs, and solenoids, and physical prototyping. The module culminates with a team design project in which students build a small Arduino-based circuit along with its physical enclosure and mechanical linkages.
