Degenerately Doped Silicon Wafers

university wafer substrates

What is a Degenerately Doped Silicon Wafer?

A Phd asked the following question:

"I am looking for a wafer which have resistivity lower than 1 ohm-cm. In order not to confront an unwanted case in the future, I just want to know what do you mean by "Degenerate Doped Si Wafer" in the description part. Do you want to say the energy difference between Fermi Level and valence band is less than 3kT or do you mean something else? "

UniversityWafer, Inc. Answered:

The concept of a degenerately doped semiconductor is not a precise one. A degenerately doped semiconductor is one that is so heavily doped that it starts acting like a metal. A degenerately doped semiconductor is one with Nc<1E18/cc which corresponds to p-type Ro<0.040 or n-type Ro<0.020. We consider degenerately doped Silicon to have Ro<0.020 Ohmcm. 

Below are some example specs that are degenerately doped Si.

Resitivities of

0.01-0.02 ohm-cm

0.001-0.005 ohm-cm

0.0001-0.0005 ohm-cm

We can also depost thermal oxide, nitride and metals on any degenerately doped silicon wafer in small and large quantities.

Degenerately Doped Silicon for MEMS Devices

A University researcher requested the following quote:

"Our lab is focused on MEMS devices. We usually use silicon and glass wafers for fabricating sensors and actuators.

In our project, we would like to pattern both top and bottom of the wafer and then etch it in a KOH solution up to the full thickness (~500µm) of the wafer. That is why I would like a thick oxide. Another option (which is actually better than just a thick oxide) is to deposit 100 nm or 300 nm LPCVD Nitride in this wafer. Is it possible? If so, what would be the price of 50 wafers (with 300 µm thermal oxide + 100/300 nm LPCVD nitride)?

We are currently looking for low resistivity (0.001-0.005 Ohm.cm) 4" silicon prime wafers, with 1µm of wet thermal oxide on both sides, similar to item 1583 in your catalog. But in our case, we would rather to have a DSP wafers (instead of the SSP of the item 1583). Is it possible to customize this item to our needs? Our idea is to buy up to 50 wafers, depending on the price. "

UniversityWafer, Inc. Quoted:

4" P <100> .01-.05 ohm-cm 500+/-25 um DSP wafers with 3000A+/-15 % of thermal oxide on both sides

Why Does Degenerately Doped Silicon acts Like a Metal!

A semiconductor that is degenerately doped shows metal-like behavior when heated. This is because the degenerately doped silicon waafers acting like a metaldopants are much heavier than the host atoms, so they can accept an electron from their neighboring atom. This is a degenerate state, so it is not a true metal. However, it can behave like a metal if the doping is high enough.

A semiconductor that is heavily doped is called a degenerately doped semiconductor. When this happens, the material becomes a metal. This is due to the fact that the Nc value is greater than 1E18/cc. This corresponds to a p-type and an n-type. As a result, a semiconductor with this property would be more difficult to work with.

A semiconductor's electrical properties depend on the amount of impurities added. Light, moderate, or high doping is termed an extrinsic semiconductor. In contrast, degenerate silicon is degenerate, which means it acts like a metal. It's also called an activated semiconductor. In the semiconductor industry, this property is used to make transistors.

When the dopants are highly concentrated, the conductivity increases. More carriers are available to conduct, which makes degenerate semiconductors more commonly used in integrated circuits. To determine the level of doping in a semiconductor, superscript plus and minus symbols are used. The former signifies an n-type semiconductor with high doping, while the latter indicates a heavily doped p-type material. While degenerately doped semiconductors have higher conductivity than intrinsic crystalline silicon, they do not have as much energy.

PHD Candiate asks:

Yes, I am looking for a wafer which have resistivity lower than 1 ohm-cm. In order not to confront an unwanted case in the future, I just want to know what do you mean by "Degenerate Doped Si Wafer" in the description part. Do you want to say the energy difference between Fermi Level and valence band is less than 3kT or do you mean something else? I am looking forward to your reply. Thank you. 

Our Engineer's Reply:

Yes, though the concept of a degenerately doped semiconductor is not a precise one. A degenerately doped semiconductor is one that is so heavily doped that it starts acting like a metal. A degenerately doped semiconductor is one with Nc<1E18/cc which corresponds to p-type Ro<0.040 or n-type Ro<0.020. We consider degenerately doped Silicon to have Ro<0.020 Ohmcm.
