Cell Lab 5N (99.999%) Silicon (P-Type Si) Pieces Evaporation Materials [1–6 mm]

High-Purity P-Type Silicon for Semiconductor and Thin-Film Applications

General Description

Cell Lab 5N (99.999%) Silicon (P-Type Si) Pieces are precision-refined evaporation materials designed for semiconductor manufacturing, thin-film deposition, and advanced coating research.
Doped with boron, this P-type silicon offers stable conductivity and consistent performance, making it ideal for metal–oxide–semiconductor (MOS) transistors, integrated circuits (ICs), data storage devices, and photoelectric coatings.

With its superior purity and controlled doping, this material ensures reliable electrical characteristics for microelectronic, energy, and optical applications under high-vacuum deposition environments.

Key Features

  • Ultra-High Purity (99.999%) – Ensures minimal contamination for semiconductor-grade performance.

  • P-Type Doping (Boron) – Provides controlled hole conductivity for electronic device applications.

  • High Thermal Conductivity (150 W/m·K) – Excellent heat dissipation for vacuum and E-beam processes.

  • Excellent Stability and Uniformity – Consistent evaporation rate and film composition.

  • Customisable Sizes and Packaging – Pieces from 1–6 mm available; other dimensions upon request.

FAQ

Q1: What is P-type silicon and how is it different from N-type?
P-type silicon is doped with boron, introducing positive charge carriers (holes), while N-type silicon is doped with phosphorus or arsenic, providing electrons as charge carriers.

Q2: What evaporation methods are suitable for P-type silicon?
It can be evaporated via E-beam evaporation or thermal evaporation using graphite or tantalum liners under high vacuum.

Q3: Can the size of the silicon pieces be customised?
Yes, Cell Lab provides customisation of size, purity, and doping concentration upon request.

Q4: What are the key precautions when using this material?
Use under vacuum or inert atmosphere to prevent oxidation, and handle with clean tools to maintain purity.
