A semiconductor chip is a compact electronic device crafted from a material that exhibits properties between a conductor, like copper, and an insulator, such as rubber. These chips play a crucial role in controlling electricity flow within various electronic devices and systems, making them essential to today's technology landscape.
The creation of semiconductor chips involves a process known as doping. This method introduces specific impurities into a pure semiconductor to alter its electrical characteristics. Following this, intricate circuits are "printed" onto the semiconductor using a series of masks, akin to creating detailed artwork, to form the necessary pathways for electrical flow.
Transistors serve as the foundational building blocks of semiconductor chips, acting as electronic switches that manage the flow of electrical current. Remarkably, a single chip can house billions of transistors, empowering it to execute a vast range of logical and computational functions effectively.
Fabrication technology encompasses the various processes and methodologies employed in the production of semiconductor chips. A key aspect of this technology is miniaturization, which facilitates the reduction of transistor sizes, allowing for more transistors to fit on a single chip. This enhancement in performance and efficiency is often quantified in nanometers (nm), indicating the size of the smallest features created on the chip.
Advancements in fabrication technology have led to the ongoing miniaturization of semiconductor chips. This trend allows for an increased number of transistors within the same chip area, enhancing processing power and efficiency while simultaneously lowering power consumption.
A wafer is a thin slice of semiconductor material, typically silicon, that serves as the substrate for the fabrication of integrated circuits. Multiple chips can be produced on a single wafer, which is subsequently diced into individual chips for use in various applications.
Once the wafer is diced into separate chips, each chip undergoes packaging in a protective casing. Tiny wires are connected for power and data transfer, and the chips are rigorously tested for functionality and reliability through a series of stress tests to ensure they meet quality standards.
India's semiconductor ecosystem has primarily centered on chip design, boasting a well-established design industry since the 1990s. Recently, the country has made significant strides in semiconductor manufacturing, with plans to establish fabrication plants and assembly and test facilities to strengthen its position in the semiconductor supply chain.
India's venture into semiconductor manufacturing builds upon its robust chip design foundation, creating opportunities for a broader spectrum of professionals, including engineers, data scientists, and material scientists. This interdisciplinary approach is set to further enrich India's semiconductor ecosystem.
