Advanced FinFET and GAA Technology for Physical Design

With the advancement of semiconductor technology, the need for faster, smaller, and more power-efficient transistors is increasing. Conventional planar transistors have reached their limit, opening the door to more complex structures such as FinFET and Gate-All-Around (GAA) Technology. These new technologies improve performance, minimise power consumption, and allow high-density integration. In this blog, we will discuss Advanced FinFET and GAA Technology, their advantages, and their influence on physical design.

Understanding FinFET Technology

FinFET (Fin Field-Effect Transistor) technology is a semiconductor design technology that breaks the confines of conventional planar transistors. Contrary to conventional MOSFETs, which are flat, two-dimensional structures, FinFET transistors are three-dimensional fin-shaped structures. This structure offers improved control over current flow, minimising leakage and maximising performance.

FinFET Advantages

• Lower Power Consumption – With improved electrostatic control, FinFET technology consumes less power compared to conventional planar transistors.
• Improved Speed – Lower leakage current and more-controlled channel equate to greater switching speed.
• Improved Performance – Greater drive current equals overall improved high-speed performance.
• Scaling – FinFET transistors scale down to microscopic nodes, so they fit neatly into advanced manufacturing processes.

Gate All Around (GAA) Technology – The Future of Transistors

While FinFET technology has been revolutionary, further miniaturisation requires even superior transistor architecture. That is where Gate All Around (GAA) Technology steps in. GAA transistors are the next-generation version of FinFETs with yet better control over the channel.

What is Gate-All-Around (GAAFET)?

GAAFET (Gate-All-Around Field-Effect Transistor) is a transistor that is surrounded by the gate on four sides of the channel. Compared to three-sided gate control for FinFETs, GAAFETs provide 360-degree gate control, with improved electrostatics and diminished short-channel effects.

Major Strengths of GAA Technology

• Better Gate Control—Because the gate covers the entire area, GAAFETs enjoy better electrostatic control than FinFETs.
• Low Power Leakage – Gate All Around transistors reduce leakage current, so they are suitable for power-constrained applications.
• Enhanced Scalability – GAA technology is likely to facilitate scaling above 3nm, driving semiconductor manufacturing into the future.
• Enhanced Performance and Efficiency – Enhanced control of current flow means enhanced energy efficiency and higher processing speeds.

FinFET vs. GAAFET – A History of Transistors

Physical Design Parameters to Consider with FinFET and GAA Technology

The physical design teams should consider the following while adopting Advanced FinFET and GAA Technology:

• Standard Cell Design – Physical design teams should tune standard cell libraries to support the new FinFET and GAAFET structures.
• Placement and Routing—Because 3D transistor structures are complex, proper placement and routing methods are responsible for achieving minimum capacitance and resistance.
• Power Management—GAA technology provides enhanced power efficiency, so the power grid design must be optimised to exploit its potential.
• Heat Dissipation—The transistor’s densification could create thermal issues. Effective thermal management practices must be incorporated into the design.
• Manufacturing Constraints – FinFET and GAAFETs necessitate high-end lithography processes and incredibly precise manufacturing methods to produce them as reliable.

While the world is transitioning to 2nm and beyond, GAAFETs will replace FinFETs in upcoming chip architecture. Intel, TSMC, and Samsung, the most prominent semiconductor leaders, are already engaged and working on GAA technology in upcoming chips. The ongoing development of Advanced FinFET and GAAFETs will revolutionise computing, AI, and mobile technology.
