The semiconductor industry has witnessed a transformative shift with the emergence of fabless semiconductor companies. In this innovative business model, companies focus on semiconductor design and intellectual property (IP) development while outsourcing the manufacturing process to external foundries. This separation of design and manufacturing responsibilities allows for greater flexibility and efficiency in bringing cutting-edge semiconductor products to market. In this article, we explore the concept of fabless semiconductor companies, their advantages, and a list of top players in the industry.

What is fabless semiconductor

In a fabless semiconductor model, a company focuses on the design and sale of semiconductor chips but does not have its own manufacturing facilities for producing the silicon wafers or chips. Instead, it relies on outsourcing the fabrication process to external manufacturing plants or foundries. This allows the company to concentrate on innovation, design, and marketing without the need for extensive investment in semiconductor manufacturing infrastructure. The term "fabless" essentially highlights the separation of chip design and manufacturing responsibilities in the semiconductor industry.

What are fabless semiconductor companies

A fabless company in the semiconductor industry refers to an enterprise model where the company develops and owns intellectual property (IP) related to semiconductor technology but outsources the actual manufacturing of semiconductor chips. In this model, the company focuses on semiconductor design, innovation, and the development of intellectual property without the need to have its own manufacturing facilities.

Typically, these companies delegate the manufacturing tasks of the designed semiconductor chips to third-party manufacturing plants or foundries. These manufacturing facilities are responsible for using their production equipment and expertise to manufacture the chips based on the design files provided by the company. Once the chips are fabricated, they are sent back to the fabless company for testing, packaging, and eventual product distribution.

The choice of this model allows fabless semiconductor companies to concentrate on innovation and design while avoiding significant capital investments in semiconductor manufacturing infrastructure. This flexibility enables these companies to rapidly introduce new products and better adapt to market demands and technological advancements.

What is fabless manufacturing

Fabless manufacturing is a business model in the semiconductor industry where a company focuses on designing and marketing semiconductor chips but does not engage in the actual manufacturing (fabrication) of the chips. Instead of owning and operating its own semiconductor fabrication facilities, a fabless company outsources the manufacturing process to third-party foundries or manufacturing plants.

Fabless manufacturing allows companies to specialize in chip design and innovation without the significant capital investment required for semiconductor fabrication facilities. This business model is prevalent in the semiconductor industry, and many well-known companies operate as fabless semiconductor firms.

Which is the largest fabless semiconductor companies

As of the second half of 2023, Nvidia emerged as the world's largest fabless semiconductor company, surpassing Qualcomm, at least temporarily. The rankings of the largest fabless semiconductor companies can be dynamic and subject to change based on various factors, including market trends, product innovations, and financial performance. 

What is the difference between semiconductor fab and fabless

The terms "semiconductor fab" and "fabless" represent two distinct approaches in the semiconductor industry, each emphasizing different aspects of the semiconductor manufacturing process. In summary, the key distinction lies in whether a company owns and operates its semiconductor fabrication facilities (semiconductor fab) or outsources the manufacturing process while focusing on design (fabless). 

Semiconductor Fab (Fabrication Facility)

A semiconductor fab, short for fabrication facility, refers to a manufacturing plant where semiconductor devices or chips are produced.

Manufacturing Focus: Semiconductor fabs are equipped with cleanrooms and specialized equipment for the fabrication process. This process involves creating integrated circuits on silicon wafers through techniques like photolithography, etching, doping, and metallization.

Ownership: Companies that operate semiconductor fabs own and manage the entire manufacturing process in-house. They invest in the infrastructure, equipment, and expertise required for chip fabrication.

Examples: Companies like Intel, Samsung, TSMC (Taiwan Semiconductor Manufacturing Company), and GlobalFoundries are known for owning and operating semiconductor fabs.

Fabless Companies

Fabless companies, on the other hand, focus on designing semiconductor chips rather than manufacturing them. The term "fabless" is a combination of "fabrication" and "less," indicating the lack of in-house fabrication facilities.

Design Focus: Fabless companies specialize in chip design, including creating the architecture, functionality, and specifications of semiconductor devices. They focus on innovation, research, and development of intellectual property (IP).

Outsourcing Manufacturing: Instead of investing in semiconductor fabs, fabless companies outsource the actual manufacturing (fabrication) of their designed chips to third-party foundries or manufacturing facilities. This allows them to leverage the expertise and infrastructure of established manufacturing plants.

Examples: Nvidia, Qualcomm, AMD (Advanced Micro Devices), and MediaTek are prominent examples of fabless semiconductor companies.

Key Differences

Ownership and Control

Semiconductor fabs own and control the entire manufacturing process, from design to fabrication. Fabless companies, on the other hand, focus solely on design and outsource fabrication to external facilities.

Investment and Expertise

Semiconductor fabs require substantial investments in manufacturing infrastructure, cleanrooms, and equipment. Fabless companies can allocate resources primarily to design and innovation without the need for extensive manufacturing expertise.


Fabless companies enjoy greater flexibility as they can adapt quickly to changes in technology and market demands without being tied to a specific manufacturing facility.

Which is the first fabless semiconductor company

In 1985, a transformative shift occurred in the semiconductor industry with the founding of Chips and Technologies by Dado Banatao and Gordon Campbell. This marked the inception of the first fabless semiconductor company, pioneering a business model that would significantly influence the industry's trajectory.
