Silicon Wafers to Micro-Machine Waveguides

Research Client Asks:

"I am looking at purchasing 100mm high resistivity silicon wafers. For my application, I need the wafers to have high carrier lifetimes (on the order of 100µs or greater), so I think they need to be float zone with high purity. The wafers can be undoped or have a slight n-type doping, along with <100> orientation. I will also be processing both sides of the wafer, so I will need double side polish. I am wondering if you have wafers that would suit my application?

I will be doing front side and back side DRIE with the wafers to micromachine waveguides. I need the high carrier lifetime as I will be exciting free carriers in the silicon using a laser."

UniversityWafer Solution:

The following wafers will work:

Si Item #3193 - 100mm Undoped <100> >10,000 ohm-cm 525um DSP Prime Grade TTV: <10um, Bow/Warp: <30um, Flat: 1

Are there examples of silicon, or other substrate, doped with binary semiconductors such as SnS, SnSe, GaP, GaAs

Research Client Asks:

"I am investigating new methods to produce doped silicon. I am curious to know if there are examples of silicon, or other substrate, doped with binary semiconductors such as SnS, SnSe, GaP, GaAs, etc. I have a second question: would there be an advantage to doped materials in which the dopant is evenly distributed throughout the substrate? My limited understanding is that most dopants are added to the substrate in a way that concentrates the dopant near the surface. In our labs we have produced binary dopants in a silicon substrate and I’m curious about the potential value of the work. I appreciate this opportunity to ask questions." 

UniversityWafer Answer

All bulk semiconductor crystals and wafers that are doped, have the dopant distributed in them as uniformly as possible. Considerable effort is made to measure both radial and axial uniformity of dopant distribution in a semiconductor ingot. CZ crystallized materials have large but predictable axial dopant variations and low Axial variation. FZ crystallized materials, gas phase doped, can have very low dopant variation throughout. Neutron Transmutation doping results in dopant variation dependent only on the uniformity of neutron Flux..

In making semiconductor devices on a bulk crystal substrate, doping is by diffusion (gas or liquid) through the wafer surface and therefore with inherent dopant gradient.

In Silicon wafers, I have not come across intentional co-doping with two or more elements.
In III-V semiconductors we have InP doped with both S and Zn. I have available GaAs:(Ga2O3+Cr), GaAs:(In+Sn), InP(Ga+Fe).

I have not ever come across Silicon doped with any III-V compounds, nor II-VI compounds.
I did come across GaAs:V2O5 and GaAs:Ga2O3.
