3D transistor architectures are advanced semiconductor designs that stack multiple layers of transistors vertically, rather than spreading them out horizontally on a single plane. This innovative approach enhances performance by increasing the density of transistors, improving electrical characteristics, and minimizing short-channel effects, which are critical as devices continue to scale down in size.

Review Questions
How do 3D transistor architectures improve upon traditional 2D designs in terms of performance and efficiency?
3D transistor architectures enhance performance and efficiency by allowing for a higher density of transistors in a smaller area. This vertical stacking reduces the distance that electrons must travel, leading to faster switching speeds and lower power consumption. Additionally, these structures minimize short-channel effects that are prevalent in 2D designs as devices scale down, resulting in better control over the electrical characteristics of the transistors.
Discuss the impact of FinFET technology as a specific type of 3D transistor architecture on short-channel effects.
FinFET technology, a prominent example of 3D transistor architectures, significantly mitigates short-channel effects by providing better electrostatic control over the channel. The fin structure increases the surface area exposed to gate control, allowing for more effective modulation of the channel even as its dimensions shrink. This results in reduced leakage currents and improved device performance compared to traditional planar transistors.
