What are Silicon Wafer Flats?

What are Silicon Wafer Flats?

PAM XIAMEN offers Silicon Wafer Flats

Since Silicon Wafers look basically the same! Flats are cut into the edge of the wafers so users could determine the wafer’s dopant-type and orientation.

Below is an example of silicon wafers flat specs:

Spec.	2”		3”	100mm	125mm	150mm	200mm	300mm
Diameter	2.000+/-.015”		3.000+/-.025”	100+/-.5mm	125+/-.5mm	150+/-.2mm	200+/-.2mm	300+/-.2mm
	50.8+/-.38mm		76.2+/-.63mm
Thicknes s	0.011+/-.001”		0.015+/-.001”	525+/-20 um or	625+/-20um	675+/-20um or	725+/-20um	775+/-20um
	279+/-25um		381+/-25um	625+/-20um		625+/-15um
Primary Flat Length	0.625+/-.065”		0.875+/-.125”	32.5+/-2.5mm	42.5+/-2.5	57.5+/-2.5mm	Notch	Notch
	15.88+/-1.65mm		22.22+/-3.17mm
Secondar y	0.315+/-.065”		0.44+/-.06”	18.0+/-2.0mm	27.5+/-2.5	37.5+/-2.5mm
Flat Length	8+/-1.65mm		11.18+/-1.52mm
Primary Flat Location	{110}+/-1 deg.		{110}+/-1 deg.	{110}+/-1 deg.	{110}+/-1 deg.	{110}+/-1 deg.	{110}+/-1 deg.	{110}+/-1 deg.

But flats are not a universal standard. You can order any silicon ingot and have the plant cut any type of flat out of the wafer. So P/Boron (100) Silicon Wafers may have just one flat.

Float-Zone Mono-Crystalline Silicon

PAM-XIAMEN can offer float zone silicon wafer, which is obtained by Float Zone method. Monocrystalline silicon rods is got through float zone growth, and then process the monocrystalline silicon rods into silicon wafers, called float zone silicon wafers. Since the zone-melted silicon wafer is not in contact with the quartz crucible during the floating zone silicon process, the silicon material is in a suspended state. Thereby, it is less polluted during the process of floating zone melting of silicon. The carbon content and oxygen content are lower, the impurities are less, and the resistivity is higher. It is suitable for the manufacture of power devices and certain high-voltage electronic devices.

Ge(Germanium) Single Crystals and Wafers

PAM-XIAMEN offers 2”, 3”, 4” and 6” germanium wafer, which is short for Ge wafer grown by VGF / LEC. Lightly doped P and N type Germanium wafer can be also used for Hall effect experiment. At room temperature, crystalline germanium is brittle and has little plasticity. Germanium has semiconductor properties. High-purity germanium is doped with trivalent elements (such as indium, gallium, boron) to obtain P-type germanium semiconductors; and pentavalent elements (such as antimony, arsenic, and phosphorus) are doped to obtain N-type germanium semiconductors. Germanium has good semiconductor properties, such as high electron mobility and high hole mobility.
