10 Questions
What is a wafer in the context of electronics?
A wafer is a thin slice of semiconductor material, such as crystalline silicon, used for the fabrication of integrated circuits and solar cells.
When did the term 'wafer' first appear in the semiconductor industry?
The term 'wafer' first appeared in the 1950s to describe a thin round slice of semiconductor material, typically germanium or silicon.
What is the Czochralski method used for in the semiconductor industry?
The Czochralski method is used to produce single-crystal ingots, which are then used to make silicon wafers.
What are the two major parts of an integrated circuit (IC)?
The two major parts of an integrated circuit are a tiny and very fragile silicon chip (die) and a package which is intended to protect the internal silicon chip and to provide users with a practical way of handling the component.
What technology is used for most of the ICs manufactured at STMicroelectronics?
MOS (Metal-Oxide-Semiconductor) technology is used for most of the ICs manufactured at STMicroelectronics.
What is the purpose of the package in an integrated circuit (IC)?
The package is intended to protect the internal silicon chip and to provide users with a practical way of handling the component.
Describe the characteristics of monocrystalline ingots used in the fabrication of semiconductor wafers.
The round shape characteristic of these wafers comes from single-crystal ingots usually produced using the Czochralski method.
Explain the significance of the MOS technology in the context of integrated circuits (ICs).
The MOS technology is used for most of the ICs manufactured at STMicroelectronics.
What are the various 'front-end' and 'back-end' manufacturing processes involved in the fabrication of electronic components?
This note describes the various 'front-end' and 'back-end' manufacturing processes, taking the transistor as an example, because it uses the MOS technology.
How were silicon wafers first introduced in the semiconductor industry?
Silicon wafers were first introduced in the 1940s.
