What Does STI Stand For?

STI stands for Shallow Trench Isolation

Shallow Trench Isolation (STI) is a semiconductor manufacturing technique used to electrically isolate individual transistors on a chip. This method involves etching shallow trenches in the silicon substrate, which are subsequently filled with an insulating material, typically silicon dioxide. STI enhances device performance by reducing parasitic capacitance and preventing electrical interference between adjacent components, thereby improving the overall reliability and functionality of integrated circuits.
