Q&A

What is high-purity silicon?

High-purity polycrystalline silicon (polysilicon) is the starting material for nearly all semiconductors, and is the largest dollar volume chemical consumed by the electronics industry.

What are 3 types of silicon wafers?

The choice of silicon wafer depends on the application. Single crystal wafers are the most common choice for ICs, while polycrystalline wafers are often used for solar cells and LEDs. Amorphous silicon wafers are less common, but they are sometimes used for applications where cost is a major consideration.

  1. Monocrystalline Silicon Wafers:
    • Monocrystalline silicon wafers are made from a single, continuous crystal structure, resulting in high purity and uniformity.
    • They offer superior electrical properties and are often used in high-performance semiconductor devices such as microprocessors and memory chips.
  2. Polycrystalline Silicon Wafers:
    • Polycrystalline silicon wafers are composed of multiple smaller crystals, resulting in lower purity and slightly reduced electrical performance compared to monocrystalline wafers.
    • They are more cost-effective to produce and are commonly used in applications where strict performance requirements are not critical, such as solar cells and display panels.
  3. Epitaxial Silicon Wafers:
    • Epitaxial silicon wafers are monocrystalline wafers with an additional layer of single-crystal silicon grown on the surface using a process called epitaxy.
    • This layer, known as the epitaxial layer, is carefully controlled to achieve specific electrical properties, making epitaxial wafers suitable for specialized semiconductor applications requiring precise doping profiles or device isolation.
