An Overview of Semiconductors: From Basic Physics to Global Impact
Semiconductors are a class of materials with electrical conductivity falling between that of a conductor and an insulator. This unique property, which can be precisely manipulated, makes them the foundational building blocks of virtually all modern electronics.
Properties and Types of Semiconductors
The behavior of semiconductors is primarily defined by their electronic band structure. Unlike metals, which have overlapping valence and conduction bands, semiconductors have a small energy gap between these bands. This "band gap" allows their conductivity to be controlled by various factors such as temperature, light, and the addition of impurities.
There are two main types of semiconductors:
Intrinsic Semiconductors: These are pure, single-element materials, such as silicon (Si) and germanium (Ge). At very low temperatures, they behave as insulators. As temperature increases, some electrons gain enough thermal energy to jump the band gap, creating a small degree of conductivity.
Extrinsic Semiconductors: These are created by "doping" an intrinsic semiconductor with impurities. This process intentionally alters the material's electrical properties.
N-type: Doped with elements that have more valence electrons (e.g., phosphorus, arsenic), creating an excess of free electrons to carry current.
P-type: Doped with elements that have fewer valence electrons (e.g., boron, aluminum), creating "holes" or electron deficiencies that act as positive charge carriers.
The combination of n-type and p-type semiconductors forms a crucial component known as a p-n junction, which is the basis for many electronic devices like diodes and transistors.
The Semiconductor Manufacturing Process
The production of a semiconductor chip is an incredibly complex and precise process, often taking several months and involving hundreds of steps. A simplified overview of the key stages is provided in the table below.
| Step | Description |
| 1. Wafer Fabrication | Highly purified silicon is grown into a single crystal ingot, which is then sliced into thin discs called wafers. The wafers are polished to an extremely flat, mirror-like finish. |
| 2. Photolithography | A light-sensitive chemical called a photoresist is applied to the wafer. A patterned mask is used to expose specific areas of the photoresist to ultraviolet (UV) light. |
| 3. Etching | The unexposed or exposed areas of the photoresist are washed away, leaving the pattern on the wafer. The exposed silicon is then etched away using chemicals or plasma to create the desired circuit patterns. |
| 4. Deposition & Ion Implantation | Thin layers of insulating and conductive materials are deposited onto the wafer. Ion implantation is used to "dope" specific regions of the wafer with impurities, creating the n-type and p-type regions. |
| 5. Assembly & Packaging | The individual circuits on the wafer are cut into "dies." These dies are then connected to a lead frame and encased in a protective package, creating the final semiconductor device. |
The Global Semiconductor Industry
The semiconductor industry is a massive and influential sector of the global economy, providing the components that power everything from smartphones and computers to cars and medical devices. The market is dominated by companies from the United States, Taiwan, South Korea, Japan, and the Netherlands.
