A Brief History of the Microchip

The microchip has a long history and has subsequently come a long way since its inception. While a recent microchip shortage has affected a range of industries, it hasn’t always been this way.

The journey this critical piece of technology has taken is fascinating and worth following. To illustrate the progression of this technology and its impressive advancement over the decades, the following is a brief look into the complete history of the microchip.

Humble Beginnings: Texas Instruments in 1958

The first microchip came about in 1958 when Texas Instruments engineer Jack Kilby developed it. At the time, Kilby couldn’t predict precisely how this invention would shape the future of electronics and tech, but his patent for this technology would prove key in the development of many products in the years to come.

Kilby recognized the issue of having capacitors, resistors, and transistors separate and the mess this created. To simplify these systems, he combined all of these components into a single solution using a solitary bar comprising semiconductive material.

This early microchip took the form of a perceivably primitive integrated circuit made of a small piece of germanium, and Kilby first put it to the test on September 12, 1958, when he successfully demonstrated its capabilities. This wasn’t Kilby’s only legacy, however—he would go on to assist with developing thermal printers and TI’s most notable invention, the hand-held calculator.

A Potential Rival in Physicist Robert Noyce

Around the same time Kilby was working on his iteration of the microchip, Robert Noyce was developing another version of an integrated circuit using a relatively small silicon chip. This chip would replace the “rat’s nests” of wiring that were far more complicated than Noyce knew they needed to be. It would allow for a more organized and compact layout that’s far more manageable.

This invention also came along in the late ’50s, on January 23, 1959, to be exact. This invention would prove invaluable to Noyce’s choice of investment, Fairchild Semiconductor Corporation based in San Jose.

Texas Instruments and Fairchild were both unaware of each other’s progress when it came to the microchip, eventually leading to a patent rivalry that led to both companies granting licenses to each other for the fabrication of integrated circuits. These companies also subsequently granted licenses to other organizations seeking to innovate with the microchip.

As a result of their convergence, Robert Noyce and Jack Kilby have established themselves as co-inventors of the modern microchip in the public eye.

Commercial Accessibility in the ’60s

A few years after Kilby and Noyce collaborated on patenting the integrated circuit, Fairchild Semiconductor Corporation made microchips commercially accessible. As of 1961, computers began incorporating microchip into their designs to replace old-fashioned transistors and other connected components.

Then, in 1962, Texas Instruments submitted its microchip for use in defense applications, namely the Minuteman Missile and computers in the U.S. Air Force. Later, in 1971, TI would use these chips in their hand-held calculators with Kilby’s help. NASA also used microchips for the first time in the Apollo missions.

Robert Noyce also went on to found the company Intel, which ultimately wound up developing the world’s first microprocessor by 1968.

Developing into Today’s Microchips

Over the years, more and more companies have turned to microchips and microprocessors to power all types of electronic devices. As time has progressed, the size of these components has also continued to shrink, as manufacturers find ways to compress large amounts of data into compact physical systems. At the same time, today’s microchips are becoming increasingly powerful even as their physical components grow smaller.

The average desktop computer had already surpassed Apollo’s computer systems by the early 2000s, with those consumer electronics capable of holding far more memory than NASA’s outdated systems. And while the technology continued to advance in the following years, it has become more affordable to the average consumer over time.

Just about every industry uses microchips in some capacity. For example, smartphones rely on microchips to remain compact and easy to carry for consumers while enabling them to perform a variety of functions. Modern vehicles also rely on microchips to power everything from the complex electronics in dashboards to safety devices and sensors.

Nanotechnology: The Future of the Microchip

The next big step in miniaturizing electronics while increasing their processing power is the development of nanotechnology. Today, everything from smartphones to desktop computers uses advanced microchips that continue to get smaller and more compact.

However, although microtechnology is highly advanced today, it still comes with certain limitations that nanotechnology will help overcome. Nanotechnology uses manufacturing methods and materials that go beyond what conventional microchips are capable of achieving. Various electronics will benefit from the use of nanotechnologies that allow for improved connectivity and processing power than what microtechnologies have to offer.

Nanotechnology will revolutionize a wide range of industries the way microtechnology has, from electronics and biomedicine to energy, environment, food and beverage, and many others. For example, solar panels using nanotechnology in lieu of microchips could become even more affordable, making it easier for various facilities to remain sustainable and energy-efficient. Electronics will also be even more compact, lightweight, and portable, which makes these products even more convenient for consumers. In the medical field, nanotechnology would also be able to help increase the precision of surgical procedures, repair damaged genes, and perform other tasks that increase the efficacy of medical treatments.

Microchips are critical today for many applications, from consumer electronics and automotive parts to defense applications. While there is an ongoing shortage of microchips that began with the pandemic, this shortage is coming to an end and all affected industries will be able to benefit from this technology more consistently once again.

The microchip has a long and complicated history, and it remains more relevant than ever in today’s technologies. Researchers continue to improve upon existing microtechnology to make it more efficient and affordable, and the future of nanotechnology will usher us into the next era of microtechnology.
