Understanding Semiconductor Wafer Production and Fabrication

Each wafer is typically between 200 to 300 millimeters in diameter and less than a millimeter thick. The slicing process generates a significant amount of silicon dust, which is carefully collected and recycled to minimize waste. After slicing, the wafers are polished to achieve a smooth and flat surface.

6 FAQs about [How many silicon wafers should be cut for silicon energy storage]

What is the diameter of a silicon wafer?

The diameter of the silicon wafers are specifi ed either in inches or mm. Although an inch is 25.4 mm, the diameters of wafers in inches are usually multiples of 25.0 mm (e.g. 4 inches = 100 mm), which should be clarifi ed beforehand with the supplier.

How many wafers can be cut from a silicon crystal ingot?

Typical wafer thickness ranges from 50-300 micrometers for semiconductor applications. How many wafers can be cut from a single silicon crystal ingot? The size of the ingot determines maximum possible wafers. A 6 inch diameter ingot can yield approximately 500-800 wafers.

What are the selection criteria for silicon wafers?

For silicon wafers, beside the crystal orientation (<100> or <111>) the doping (n- or p-type) as well as the resistivity (Ohm cm) are selection criteria. Silicon wafers usually come as „Prime-grade“ or „Test-grade“, latter mainly have a slightly broader particle specification.

Can silicon wafers be recycled?

The brittleness of silicon crystals combined with the realities of fixed diameter ingots means that only 30-40% of the original cylindrical ingot mass results in usable wafers. The removed material cannot be easily recycled. How fast do modern machines cut silicon wafers?

How long does it take to cut a wafer?

The wire spacing and the wire diameter determine the wafer thickness and the kerf-loss. The length of wire is on the order of hundreds of kilometers, and runs at a speed of ~20m/sec. A cut takes about 5 to 8 hours. The slurry is continuously fed and acts as both the cutting material and the coolant.

What are silicon wafers used for?

Over 90% of silicon wafers become the foundation substrate for fabrication of semiconductor devices like computer chips and integrated circuits via deposition of transistors and circuitry onto their surfaces. Silicon ingot cutting into delicate wafers, pivotal for electronics, requires rigorous and balanced manufacturing.
