Fz Semiconductor Wafer And Its Uses

FZ wafers or float zone wafers are thin slices of silicon crystals in their purest form, which is acquired by the procedure of verticle zone melting. In this state, there is no need of using a vessel for maintaining the silicon either and for this reason the issue of contamination is quickly avoided, resulting in the purest type of silicon wafers known as FZ wafers.

Purity level of FZ wafers

In wafers of float zone silicon, the quantity of the contaminations that are discovered in abundance in other semiconductor wafers like carbon, oxygen and nitrogen are even rather reduced. Regardless of the addition of this contamination, the FZ wafers proceed to be the purest silicon wafers and hence, are still one of the best options to all various other semiconductor wafers available for use in photovoltaics and also electronics.

The process of manufacturing FZ wafers.

FZ wafers are made from float zone silicon which is made by one of the most clever and also difficult crystal growth techniques ever. In the production of all various other semiconducting product it is held horizontally however for making float zone silicon, it is held vertically. It is after that drawn for rather some time prior to finally acquiring float zone silicon.

It results from the limits from the surface tension of the silicon that the float zone wafers acquired from it are generally minimal compared to one Hundred and fifty millimetres in diameter. However, the size has nothing to do with the resistivity in this case and for this reason the FZ silicon wafers make the best semiconductors.

Applications of Float Zone Wafers

There are specific uses of float zone wafers that only work on the usage of these wafers only. Right here are some examples:

1. Making from Optical Components: The use of float zone wafers for the production of optical components like tetra hertz exposure window and also lenses that are used by the people exposed to tetra hertz radiation is crucial. It is the characteristic feature of FZ wafers to be transparent to tetra hertz radiation and also it is due to this feature that it proves to be an advantage for physicians that use tetra hertz radiation for medical applications.

2. Making from High Volume Production Solar Cells: Another characteristic feature of FZ silicon wafers is that they have twenty-five percent extra solar conductivity compared to other semiconductor wafer. This makes it an ideal selection for being utilized in the solar cells considering that they take in a lot more heat from the same unit of area compared to their other counterparts. These are much more costly, the quantity of solar energy they fetch more than makes up for their price. The factor behind their being much better conductor is the existence of minimal impurities in them.

Various other uses of FZ wafers include their use in the photodetectors that sense electro-magnetic energy and power semiconductor tools like rectifiers, thyristors as well as some unique sort of power transistors that are utilized primarily for protection purposes.

FZ wafers or float zone wafers are thin pieces of silicon crystals in their purest form, which is obtained by the process of verticle zone melting. In this state, there is no necessity of making use of a vessel for keeping the silicon either as well as therefore the trouble of contamination is quickly avoided, resulting in the purest type of silicon wafers understood as FZ wafers.

In wafers of float zone silicon, the amount of the contaminations that are discovered in wealth in other semiconductor wafers like nitrogen, oxygen and also carbon are additionally fairly reduced. Regardless of the addition of this pollutant, the FZ wafers proceed to be the purest silicon wafers as well as therefore, are still one of the finest alternatives to all other semiconductor wafers available for use in electronics as well as photovoltaics. Making of High Volume Production Solar Cells: Another characteristic feature of FZ silicon wafers is that they have twenty-five percent extra solar conductivity than any other semiconductor wafer.
