Product Description: Si wafer silicon substrate 12 inch N type Dummy grade diameter 300mm thickness 750μm

Silicon wafers are usually cut from high purity monocrystalline silicon rods. High purity monocrystalline silicon rods are prepared by Czochralski process or Float zone process, and then silicon wafers are made by cutting, polishing and other processes. Common silicon wafer diameters are 3 inches, 4 inches, 6 inches, 8 inches, 12 inches and other specifications. Wafer thickness is generally between 0.5-0.7 mm. Silicon wafers can adjust their electrical properties by mixing different impurity elements (such as phosphorus and boron) to create N-type or P-type silicon materials. This is important for the manufacture of various integrated circuits and semiconductor devices. The surface of the silicon wafer needs to be polished and cleaned to remove surface defects and contamination and ensure that the surface of the wafer is smooth.

Features:

· Crystal structure: Silicon is a typical elemental semiconductor with a regular diamond crystal structure with ordered atoms, which provides a good basis for its electronic properties.

· Electronic properties: Silicon has a band-gap width of about 1.12eV, is between an insulator and a conductor, and can generate and recombine electron-hole pairs under the action of an applied electric field, thus showing good semiconductor properties.

· Dopability: Silicon can adjust its conductive type and resistivity by incorporating Group III (e.g. B) or Group V (e.g. P, As) impurity elements, providing the possibility for the manufacture of various semiconductor devices.

· Oxidizability: Silicon can chemically react with oxygen at high temperatures to form a dense and uniform silicon dioxide (SiO2) film, which lays the foundation for silicon-based integrated circuit processes.

· Mechanical properties: Silicon has high hardness, strength and chemical stability, which is conducive to subsequent cutting, polishing and other processing processes.

· Size and size: Silicon wafers can be prepared into discs ranging in diameter from 2 inches to 12 inches to meet the needs of different processes.


Applications:


1. Sensors: Silicon-based sensors are widely used in electronic equipment, industrial control, automotive electronics and other fields, such as pressure sensors, acceleration sensors, etc.

2. Optoelectronic devices: Use the photoelectric properties of silicon materials to manufacture photodetectors, solar cells, light-emitting diodes and other optoelectronic devices.

3. Rf and microwave devices: Silicon-based chips can be used to manufacture microwave and millimeter wave integrated circuits such as RF amplifiers, switches, and power amplifiers.

4. Biomedical devices: Silicon-based biocompatibility makes it an ideal material for biosensors and implantable medical devices.


Note: Used in test experiments, there are slight scratches.

    Detailed tracking information will be offered to your mailbox in an automatic manner as long as we officially dispatched your package from our sorting center.
    Customer is advised to check more tracking information from “My Account” after the account sign in.
    It occasionally comes to the situation for no displaying of tracking information after the receiving of shipment notification. Please be advised to wait for 1-2 business days until the updating of pertinent tracking information in your account center.

  • Expedited shipment

    The changing of the shipping methods may have occurred when we are noticed from customer for the needing of rush order or lower rate of shipment delay. The related request is acceptable whenever in prior of the order is dispatched and heading to the designated shipping address.
    Note: (PO) boxes or FPO/APO military addresses can only be shipped out by standard shipping method).
    The shipping fare for the expedited shipment method may higher than the standard one you chose for, then please be aware that you may ask to pay for the balance for the pertinent shipment substitution. You are welcome to contact our customer service via “contact us” for further inquiry and requisition.

  • Shipping cost all about

    It is deeply appreciated to take your kind pardon for any misunderstanding about the shipping price due to the package is shipped from China.
    The contract we have stipulated with FedEx, DHL, UPS and EMS is already set and therefore all merchandise is sent via Air rather than Ground. While this may not be the most cost effective for all customers, in terms of delivery time, ease of shipment and reliability we have determined that this is the most effective overall.
    The shipping cost for all merchandises are displayed by adding items to your shipping bag, you can estimate shipping time and cost and acquire more shipping cost information from our site.

  • International Shipping

    International shipping costs are calculated in U.S. currency based on estimated shipment weight and destination. Shipping costs for orders placed on the website are fairly accurate, but there are times when those estimates are incorrect. If we need to adjust shipping charges for your order we will contact you to authorize those additional shipping charges.
