The emergence of computers and transistors, as well as the innovation and manufacturing technology of MOSFETs 2

In 1947, researchers Joseph Sibermann and William Shockley at Bell Labs invented the transistor. A transistor is a semiconductor device used to control the flow of electric current, and it can function as an electronic switch or amplifier. The invention of the transistor marked a significant milestone in computer technology.

Innovation and Manufacturing Technology of Transistors

The invention of the transistor spurred the rapid development of computer technology. Over time, researchers continuously improved the performance and manufacturing processes of transistors. The MOSFET is a type of transistor and a common modern transistor.

The MOSFET (Metal-Oxide-Semiconductor Field-Effect transistor) is a type of transistor based on the field-effect principle. It consists of metal, oxide, and semiconductor materials. When a voltage is applied to the metal gate, the electric field alters the electron concentration in the semiconductor material, thereby controlling the flow of current. MOSFETs are highly controllable and reliable, making them widely used in various electronic devices, particularly computers.

The innovation and manufacturing technology of MOSFETs can be traced back to the 1960s. During this period, researchers began using silicon as a semiconductor material and adjusted the transistor's performance by varying the impurity doping levels. Additionally, they improved the transistor fabrication process, such as employing photolithography to create transistor structures.
