Precision-Crafted for Advanced Technologies

Our N-doped silicon wafers combine high purity, precise mechanical properties, and customizable dimensions to meet stringent industrial and research requirements. The use of phosphorus doping and controlled chemical composition ensures consistent electrical and physical performance, making them ideal for semiconductors and advanced MEMS devices.


Cleanroom Handling and Secure Packaging

Each wafer is handled under ultra-clean conditions and is cleanroom packed in a single wafer cassette, minimizing the risk of contamination. This careful packaging not only preserves wafer integrity but also streamlines storage and transportation for our customers throughout India and worldwide.

FAQs of N DOPED SILICON WAFER:


Q: How are the N-doped silicon wafers customized for different applications?

A: Customization is achieved by adjusting resistivity (1-10 cm), thickness, surface finish (single or double polished), crystal orientation (<100> or <111>), and edge type (beveled or flat). These parameters cater to specific requirements in microelectronics, photovoltaics, MEMS, and research sectors.

Q: What quality control measures ensure the wafers purity and physical properties?

A: Strict controls are in place for oxygen and carbon content (<16 ppma and <2 ppma, respectively), TTV (<5 m), bow/warp (<40 m), and moisture (<0.01%). Advanced processing and inspection techniques guarantee 99.999% purity and high mechanical strength.

Q: When is it necessary to choose a particular crystal orientation for my project?

A: Select <100> orientation for most microelectronic device fabrication due to its advantageous etching properties, or <111> for applications requiring higher mechanical robustness. Orientation choice depends on the process requirements and end-use application.

Q: Where are these wafers commonly used in industry and research?

A: They are widely applied in microelectronics manufacturing, solar cell production, MEMS devices, and as research substrates. Our wafers serve dealers, exporters, manufacturers, and researchers in India and internationally.

Q: What is the advantage of single versus double side polished surfaces?

A: Single side polished wafers suit processes where only one pristine surface is needed, often reducing cost. Double side polishing is chosen when both surfaces require low roughness and enhanced uniformity, essential for certain high-precision or double-sided device structures.

Q: How is the integrity of each wafer maintained during delivery?

A: Each wafer is packaged in a cleanroom environment and placed into a single wafer cassette, ensuring it remains free from particulate and moisture contamination throughout handling, transport, and storage.

Q: What benefits does N-type (phosphorus-doped) silicon provide compared to other doping types?

A: N-type wafers, doped with phosphorus, deliver excellent carrier mobility and consistent electrical properties, promoting performance stability and reliability in devices such as transistors, MEMS, and photovoltaic modules.
