Alpha Nanotech 4” Silicon Wafer P-Type Prime

Description

Product Overview

The Alpha Nanotech Prime‑Grade 4” Silicon Wafer is engineered for high‑precision laboratory and research environments where material consistency and surface quality are paramount. Manufactured by Alpha Nanotech Inc., a trusted name in semiconductor substrates, this wafer features a P‑type doping profile achieved through boron implantation, delivering reliable electrical characteristics for a wide range of applications. The wafer measures 4 inches in diameter with a thickness of 525 µm, providing a robust platform for both experimental and production‑scale processes.

Key physical specifications include a polished front surface that ensures low optical scatter and an etched back surface that facilitates easy handling and mounting. Surface flatness parameters are tightly controlled: Total Integrated Roughness (TIR) is less than 3 µm, Total Thickness Variation (TTV) is under 10 µm, Bow (BOW) remains below 10 µm, and surface roughness is kept under 0.5 nm. These tolerances guarantee that the wafer will perform consistently across multiple cycles of photolithography, ion implantation, and other semiconductor fabrication steps.

Usage

Designed for autoradiography supplies, this wafer excels in applications that require high‑resolution imaging of radioactive samples. Researchers in molecular biology, radiochemistry, and materials science can leverage the wafer’s pristine surface to achieve clear, reproducible autoradiographic prints. Beyond autoradiography, the wafer is suitable for semiconductor device prototyping, thin‑film deposition, and surface analysis techniques such as atomic force microscopy (AFM) and scanning electron microscopy (SEM).

Its prime‑grade classification makes it an ideal choice for academic laboratories, industrial R&D facilities, and specialized testing centers that demand strict adherence to material standards. The wafer’s dimensions and doping type are compatible with standard wafer handling equipment, including robotic loaders, spin coaters, and vacuum chucks, ensuring seamless integration into existing workflows.

FAQ

What does “Prime‑Grade” mean for this wafer?

Prime‑Grade indicates that the wafer meets the highest industry standards for purity, crystallographic orientation, and surface flatness. It is suitable for applications where any deviation in material quality could affect experimental outcomes.

Can this wafer be used for both autoradiography and semiconductor fabrication?

Yes. The wafer’s P‑type doping, precise thickness, and low surface roughness make it versatile for imaging techniques as well as for device prototyping, thin‑film deposition, and other semiconductor processes.

What handling precautions should be taken to avoid damaging the wafer?

Handle the wafer with clean, lint‑free gloves and use standard wafer carriers or vacuum chucks designed for 4‑inch substrates. Avoid contact with abrasive materials and store the wafer in a static‑controlled environment to prevent contamination.

Is the wafer compatible with standard photolithography equipment?

Absolutely. Its 4‑inch diameter and 525 µm thickness conform to the specifications of most photolithography tools, spin coaters, and exposure systems used in research and small‑scale production.

What is the warranty or return policy for this product?

Alpha Nanotech offers a 30‑day warranty against manufacturing defects. If the wafer arrives damaged or does not meet the stated specifications, contact our support team for a replacement or refund.
