Case Study: Samsung Electronics Co., Ltd. – Scaling 3nm GAA (MBCFET) Technology in 2025
Introduction
In the highly competitive semiconductor landscape, Samsung Electronics has consistently positioned itself as one of the pioneers in advanced chip manufacturing. The year 2025 marked a defining moment for the company as it successfully scaled and commercialized its second-generation 3nm Gate-All-Around (GAA) technology, branded as Multi-Bridge Channel FET (MBCFET™). This transition was not just an incremental step from FinFET to GAA but a major architectural leap that positioned Samsung ahead of competitors in both mobile and high-performance computing (HPC) segments.
This case study explores how Samsung leveraged its MBCFET™ innovation, forged strategic partnerships, and achieved tangible financial and technological gains.
Company Overview
- Company Name: Samsung Electronics Co., Ltd.
- Headquarters: Suwon, South Korea
- Core Business Units: Semiconductor Foundry, Memory, Consumer Electronics, Display, Mobile
- Foundry Competitiveness: Second largest global foundry player after TSMC, with a strong focus on cutting-edge nodes (3nm, 2nm, and beyond).
Offering – Samsung’s 3nm GAA-Based Process (MBCFET)
Samsung’s MBCFET™ represents a revolutionary transistor structure that overcomes the physical and performance limitations of FinFETs, which have been the backbone of chip manufacturing since 2011. Unlike FinFETs, which rely on 3D fins to control current, GAA uses nanosheets with gates wrapped around all four sides of the channel. This structure allows better electrostatic control, improved energy efficiency, and scaling potential for nodes below 3nm.
The key differentiation of Samsung’s approach is the Multi-Bridge Channel FET concept, where multiple nanosheets are stacked to provide design flexibility. This makes it easier for customers to balance performance and power requirements across a wide range of applications.
Detailed Case Study
In 2025, Samsung achieved a critical milestone: scaling its second-generation 3nm GAA technology for both smartphone system-on-chips (SoCs) and high-performance computing (HPC) processors.
