Learning outcomes

After successful completion of the course, students are able to...

  • Understand how ambient-dependent material properties of semiconductor films can be applied for sensor devices.
  • Describe the working principles of several key semiconductor-based sensors, such as temperature sensors, chemical and gas sensors, and optoelectronic sensors.
  • Simulate the operation of semiconductor sensors using available simulation tools.
  • Describe and partially implement key methods for the simulation of semiconductor sensors based on variations in temperature, current, potential, etc.
  • Apply their knowledge in the design of simulation tools in the area of technology computer-aided design (TCAD) tools for semiconductor sensors.
  • Apply advanced numerical methods (e.g., time domain finite difference – TDFD).

Subject of course

The lecture will give an overview of the manipulation of the conductivity of a semiconducting material in order to create sensor devices and their modeling and simulation. Furthermore, the course will build on existing semiconductor knowledge in order to introduce the beneficial uses of semiconductors beyond transistors for digital and analog circuitry. The course will discuss, but is not limited to, the following devices:

  • Diode temperature sensor: Students will study the P-N junction from a different angle. They will look into how this unique structure is being used as a temperature sensor and how to model it.
  • BioFET: The transducer element in BioFETs is an Ion-sensitive field-effect transistor (ISFET), which is commonly used to measure ion concentrations in a solution (such as pH). How a MOSFET can be modified to create an ISFET and BIOFET will be discussed as well as how these devices can be simulated.
  • Gas sensor: Chemical reaction taking place at the surface of a semiconductor metal oxide gas sensor will be described. In addition to electro-thermal-mechanical simulations of the complex MEMS structure required for these devices will be described.
  • CMOS image sensor: An understanding of the operation of a CMOS image sensor, its benefit against the alternatives, and techniques for its modeling will be described.
  • Optoelectronic sensors: Devices such as nondispersive infrared (NDIR) and single-photon avalanche diode (SPAD) sensors will be described. This will include a hands-on component working in a time domain finite difference (TDFD) environment to solve optoelectronic problems.

Teaching methods

The teaching methods used in the course will include a combination of four learning styles: visual, verbal, logical, and solitary. The visual methods will include showing experimental and simulation results related to the different semiconductor sensors, while the verbal will primarily be used during the course of the teaching in the lectures. Logical and solitary learning will be applied during the exercises, where the students will have to critically analyze a problem and devise a solution on their own.
