The first solid-state integrated circuit was demonstrated in the 1950s.

Explanation:

Solid-State Integrated Circuit:
A solid-state integrated circuit, also known as a microchip or simply an IC, is a miniaturized electronic circuit that consists of various electronic components such as transistors, resistors, capacitors, and diodes fabricated on a small piece of semiconductor material, usually silicon. These components are interconnected to perform specific functions, such as amplification, switching, and data processing. The invention of the solid-state integrated circuit revolutionized the field of electronics by enabling the development of smaller, more efficient, and more reliable electronic devices.

The demonstration of the first solid-state integrated circuit was a significant milestone in the history of electronics. It marked the beginning of a new era of miniaturization and paved the way for the development of modern electronics.
