Semiconductors

Optical and X-ray techniques are powerful ways to characterize semiconductor thin films. They can be used to measure film thickness, purity and crystalline quality, and for compositional analysis. Modern techniques are fast, turn-key, and generally non-destructive, allowing for rapid assessment of material properties. This course describes the fundamentals of [...]

Course 2 begins with the definitions of resistivity and sheet resistance of semiconductors and metals and emphasizes the importance of working with the correct units for each. We see how to calculate the sheet resistance of a thin conducting film once we know its resistivity. A method to determine [...]

Electron and ion beams are widely used for both qualitative and quantitative analysis of semiconductor materials and devices. They can be used to image structures with sub-nm resolution and to provide information about elemental composition and dopant concentration. This course describes the fundamentals of electron and ion beam characterization [...]

The goal of this course is to review the fundamentals of semiconductor materials, p-n junction diodes, and MOS capacitors. There are many semiconductor technologies based on different material systems, but the most important is complementary metal-oxide-semiconductor, or CMOS for short. This course will focus on semiconductor materials and devices [...]

MOSFET transistor switches are the workhorse of semiconductor-based electronics. In this course, we begin with MOS capacitors and see how to extract the oxide charge density, which is important for controlling the MOSFET threshold voltage. We then review MOSFET electrical characteristics and see how current-voltage measurements are used to [...]

This course can also be taken for academic credit as ECEA 5721, part of CU Boulder’s Master of Science in Electrical Engineering. This course is primarily aimed at first year graduate students interested in engineering or science, along with professionals with an interest in power electronics and semiconductor [...]

This course aims to provide a general understanding of semiconductor process. This course explores the principles and basic theory of semiconductor device and process. Furthermore, the students will learn the overall semiconductor process such as oxidation, diffusion, ion implantation, lithography, etching, thin film deposition, plasma, metallization, and [...]

This course will cover various aspects of microelectronics and nanoelectronics. This field aims to advance and improve the functionality of electronic devices by scaling transistors to smaller feature sizes. The course will introduce you to essential concepts such as length scales, transistor actions, and feature sizes of integrated [...]
