Who is Federico Faggin?

Born in Vincenza, Italy, in 1941, Federico Faggin is an engineer, inventor, physicist, and entrepreneur. He is famous for leading the team that invented the first commercial microprocessor and silicon gate technology, with both precursors to the explosive development of computers over the past five decades. 

Education and early career

After graduating from a technical high school, Faggin undertook work experience with Olivetti in Borgolombardo, Italy, in 1960. There, he developed his first computer at the age of 19, which later paved the way for the world’s first desktop electronic calculator. 

Faggin then enrolled at the University of Padua and received a doctorate in physics in 1965. He worked briefly at the university as an assistant professor before working as a senior engineer at CERES and then at SGS Fairchild in Milan.

At the latter, he devised a method for manufacturing metal oxide semiconductor (MOS) integrated circuits and designed two such circuits that were commercial. 

Fairchild in Palo Alto

Faggin moved to California in 1968 to join SGS Fairchild’s parent company Fairchild Semiconductor. Whilst there, he developed MOS silicon gate technology which was to become the foundation of all modern CMOS integrated circuits.

Silicon gates were faster, required less space, and used less energy than the aluminum gates they replaced. Today, almost 90% of all semiconductors use this technology.


Two years later, in 1970, Faggin joined Intel where he applied silicon gate technology to devise a new method for random logic chip design. In collaboration with Japanese electronics engineer Masatoshi Shima as well as colleagues Stanley Mazor and Ted Hoff, he developed a single chip that could perform the functions of several chips. 

The chip, known as the Intel 4004, became the world’s first commercial microprocessor.

Zilog and others

Faggin decided to found Zilog Corporation in 1974, the first such company to focus entirely on the emergent microprocessor (MP) and microcontroller (MC) market. 

Zilog’s most influential product is the Z80 series of microprocessors which became common in computers and some arcade games such as Pac-Man in the 1980s. More than 1 billion of these were sold over a production run that lasted over 20 years. 

Zilog was acquired by Exxon in 1981, with Faggin subsequently leaving the company to found two more companies. The first, Cygnet Technologies, manufactured intelligent data and voice peripherals for PCs. The second, founded in 1986 as Synaptics Inc., specialized in neural network technology and was a pioneer of touchpads and touchscreens.


Faggin was awarded the Marconi Foundation Fellowship in 1988 for his pioneering contributions to the microprocessor. 1988 also saw him awarded the Gold Medal for Science and Technology by the Italian President. 

Six years later, Faggin received the W. Wallace McDowell Award from the Institute of Electrical and Electronics Engineers (IEEE) for his work on silicon gate technology. He was then inducted into the National Inventor’s Hall of Fame in 1996 and shared the Kyoto Prize (1997) with Hoff, Mazor, and Shima from his time at Intel.

His crowning achievement came in 2010 when Faggin received the National Medal of Technology and Innovation. This is widely regarded to be the most prestigious award in the United States for achievements related to technological progress.

The Faggin Foundation

More recently, in 2015, Faggin established the Faggin Foundation to support “various programs at US universities and institutes to advance the understanding of consciousness through theoretical and experimental research.”

Faggin’s curiosity about consciousness started in the 1980s when he considered whether it was possible to create a conscious computer. He also hinted at the motivation for starting the foundation, noting that despite claims in the 60s that computers would soon be smarter than humans, modern computers are no more conscious than those developed half a century ago.

Key takeaways:

  • Born in Vincenza, Italy, in 1941, Federico Faggin is an engineer, inventor, physicist, and entrepreneur who is perhaps most notable for developing the first commercial microprocessor.
  • At SGS Fairchild in Milan, Faggin devised a method for manufacturing metal oxide semiconductor (MOS) integrated circuits and designed two that were commercial. At the company’s parent organization in California, Faggin then designed silicon gates that were faster, less energy intensive, and required less space than the existing aluminum-based designs.
  • Faggin founded the Zilog Corporation in 1974, the first company to focus on the emergent microprocessor (MP) and microcontroller (MC) market. More than 1 billion of the Z80 series of microprocessors were sold over more than 20 years with most ending up in personal computers.

Business Model Innovation

Business model innovation is about increasing the success of an organization with existing products and technologies by crafting a compelling value proposition able to propel a new business model to scale up customers and create a lasting competitive advantage. And it all starts by mastering the key customers.

Innovation Theory

The innovation loop is a methodology/framework derived from the Bell Labs, which produced innovation at scale throughout the 20th century. They learned how to leverage a hybrid innovation management model based on science, invention, engineering, and manufacturing at scale. By leveraging individual genius, creativity, and small/large groups.

Types of Innovation

According to how well defined is the problem and how well defined the domain, we have four main types of innovations: basic research (problem and domain or not well defined); breakthrough innovation (domain is not well defined, the problem is well defined); sustaining innovation (both problem and domain are well defined); and disruptive innovation (domain is well defined, the problem is not well defined).

Continuous Innovation

That is a process that requires a continuous feedback loop to develop a valuable product and build a viable business model. Continuous innovation is a mindset where products and services are designed and delivered to tune them around the customers’ problem and not the technical solution of its founders.

Disruptive Innovation

Disruptive innovation as a term was first described by Clayton M. Christensen, an American academic and business consultant whom The Economist called “the most influential management thinker of his time.” Disruptive innovation describes the process by which a product or service takes hold at the bottom of a market and eventually displaces established competitors, products, firms, or alliances.

Business Competition

In a business world driven by technology and digitalization, competition is much more fluid, as innovation becomes a bottom-up approach that can come from anywhere. Thus, making it much harder to define the boundaries of existing markets. Therefore, a proper business competition analysis looks at customer, technology, distribution, and financial model overlaps. While at the same time looking at future potential intersections among industries that in the short-term seem unrelated.

Technological Modeling

Technological modeling is a discipline to provide the basis for companies to sustain innovation, thus developing incremental products. While also looking at breakthrough innovative products that can pave the way for long-term success. In a sort of Barbell Strategy, technological modeling suggests having a two-sided approach, on the one hand, to keep sustaining continuous innovation as a core part of the business model. On the other hand, it places bets on future developments that have the potential to break through and take a leap forward.

Diffusion of Innovation

Sociologist E.M Rogers developed the Diffusion of Innovation Theory in 1962 with the premise that with enough time, tech products are adopted by wider society as a whole. People adopting those technologies are divided according to their psychologic profiles in five groups: innovators, early adopters, early majority, late majority, and laggards.

Frugal Innovation

In the TED talk entitled “creative problem-solving in the face of extreme limits” Navi Radjou defined frugal innovation as “the ability to create more economic and social value using fewer resources. Frugal innovation is not about making do; it’s about making things better.” Indian people call it Jugaad, a Hindi word that means finding inexpensive solutions based on existing scarce resources to solve problems smartly.

Constructive Disruption

A consumer brand company like Procter & Gamble (P&G) defines “Constructive Disruption” as: a willingness to change, adapt, and create new trends and technologies that will shape our industry for the future. According to P&G, it moves around four pillars: lean innovation, brand building, supply chain, and digitalization & data analytics.

Growth Matrix

In the FourWeekMBA growth matrix, you can apply growth for existing customers by tackling the same problems (gain mode). Or by tackling existing problems, for new customers (expand mode). Or by tackling new problems for existing customers (extend mode). Or perhaps by tackling whole new problems for new customers (reinvent mode).

Innovation Funnel

An innovation funnel is a tool or process ensuring only the best ideas are executed. In a metaphorical sense, the funnel screens innovative ideas for viability so that only the best products, processes, or business models are launched to the market. An innovation funnel provides a framework for the screening and testing of innovative ideas for viability.

Idea Generation


Design Thinking

Tim Brown, Executive Chair of IDEO, defined design thinking as “a human-centered approach to innovation that draws from the designer’s toolkit to integrate the needs of people, the possibilities of technology, and the requirements for business success.” Therefore, desirability, feasibility, and viability are balanced to solve critical problems.
