Between 1983 and 1986, SID Microeletrônica designed the first Brazilian chip, a landmark of national engineering and the foundation of today's semiconductor industry.
In the 1980s, while the world was consolidating the microelectronics era, Brazil took a historic leap. SID Microeletrônica, based in Campinas (São Paulo), developed the first Brazilian integrated circuit for commercial use. Manufactured between 1983 and 1986, the national chip was a landmark of engineering, innovation and technological sovereignty, paving the way for the local production of semiconductors and embedded systems.
Throughout the 1980s, Brazil operated under the informatics market reserve, a policy that encouraged the creation of domestic hardware and software companies. The aim was to reduce external dependence and build a homegrown technological base. In this setting, microelectronics research hubs emerged at universities such as UNICAMP and USP, alongside industrial centres in São Paulo and Rio de Janeiro.
SID Microeletrônica, founded by engineers and physicists trained at UNICAMP, stood out as the first Brazilian company dedicated to the prototyping, design and packaging of integrated circuits. The project was supported by FINEP, CNPq and the Research and Development Centre (CPqD) of Telebrás.
SID's chip was an ASIC (Application-Specific Integrated Circuit), developed using 5-micrometre NMOS technology. Its design was produced on Apollo graphics workstations, and the photolithographic masks were made in the company's own laboratory — a remarkable achievement for the period.
The device held roughly 5,000 transistors and was intended for telecommunications control and industrial automation applications. The packaging used ceramic and gold-plated metal pins, ensuring durability and thermal resistance. Although modest in processing power, the chip represented complete mastery of the design and fabrication cycle — from concept to finished product.
SID's technical team was led by Eng. Eduardo Leite and Eng. Roberto Lotufo, both trained at UNICAMP with specialisations in integrated circuits and lithography. The team also included researchers from ITA and USP, as well as electronics technicians trained by SENAI and the Institute for Technological Research (IPT).
In 1984, the first functional prototype was tested and validated by CPqD, which confirmed that performance met the specifications. In 1986, SID released the first commercial batch of Brazilian chips, destined for telecommunications equipment controllers and embedded industrial systems.
SID Microeletrônica's chip marked the beginning of the Brazilian semiconductor industry. Mastery of design and packaging technology opened the way for later initiatives, such as the Renato Archer Information Technology Centre (CTI) and the CI-Brasil Programme launched in the 2000s.
The initiative showed that the country was capable of developing advanced microelectronics, provided there was support for research and integration between universities and industry. It is estimated that more than 20 engineers trained on the SID project went on to work in automation and advanced technology companies, multiplying the knowledge they had acquired.
The chip used a monocrystalline silicon substrate produced abroad, but the entire process of lithography, doping and packaging was carried out in Brazil. The masks were etched onto glass by electron beam, and the metal layers were formed from vacuum-deposited aluminium. The sealed ceramic packaging provided greater durability and protection against humidity and thermal variation.
The manufacturing process followed environmental control standards, with effluent treatment and gas recovery. SID's laboratory was one of the first in the country to adopt clean production protocols in the electronics field.
Although the microelectronics sector is known for its high energy consumption, the Brazilian project introduced pioneering sustainability practices: reuse of deionised water, metal recycling and control of chemical emissions. SID demonstrated that advanced technology and environmental responsibility can coexist.
The national chip's indirect impact was also ecological: by replacing imported components, it reduced the transport footprint and the emissions associated with international logistics.
The development of the Brazilian chip established the country as a scientific leader in Latin America. It generated knowledge, infrastructure and public policies that culminated in modern programmes such as CI-Brasil and PADIS (the Support Programme for the Technological Development of the Semiconductor Industry).
The project also had an educational role: it trained microelectronics specialists and inspired the creation of electrical engineering and computing courses focused on integrated circuit design. Today, SID's principles live on in the start-ups and laboratories that continue the legacy of Brazilian microelectronics.
SID Microeletrônica's chip was more than a circuit — it was a symbol of Brazilian scientific and industrial capability. It showed that local innovation, when combined with long-term policy and environmental commitment, can transform the technological base of a nation. Ecobraz's Virtual Museum of Electronics preserves this achievement as an example of intelligent engineering and technological sovereignty.
