What is semiconductor device characterization?

Semiconductor device characterization is the process of measuring and analyzing the electrical, thermal, and physical properties of semiconductor devices such as transistors, diodes, and integrated circuits. This process helps engineers understand device performance, verify manufacturing quality, and optimize designs for specific applications. Characterization typically involves a range of tests, including current-voltage (I-V), capacitance-voltage (C-V), and reliability measurements, using specialized equipment. The data obtained guides improvements in device fabrication and ensures that products meet required specifications.
