Thin Silicon Wafers

Whey spend more on thin silicon wafers when we sell them for a deep discount to our competitors.

A Phd candidate requested a quote on the following:

We are trying to develop a new process using thin silicon, but we don't know if it"s going to work or not, so I"m reluctant to shell out to buy a set of your nice thinned-down wafers.

However, we could test our process with some scrap thin-silicon
material, if you have some amount of breakage in your thinning
process.

We would be looking for silicon <=50um thick, with a preference for<=25um and a minimum thickness of maybe 10um.  DSP would be safest but we can probably use SSP just as well.

We would dice your scrap pieces down to about 1cm x 1cm for our tests, so we"d like to get pieces bigger than 1 cm x 1cm if possible.  It's OK if the pieces are different thicknesses, and any doping level is fine.

We could start testing with just a few cm^2 of material.

Please let me know if you can help us out.

Thicknesses <10um available from diameters <25.4mm - 300mm.

We want to try using thin silicon as the lower level of a mask for
electroforming MEMS-type structures from gold.  silicon may provide substantial advantages for our process because it will be resistant to the solvents and solutions used in subsequent processing steps and can be completely removed from complex shapes using XeF2.

What Silicon Wafers are Used in Integrated Photovoltaics

Integrated photovoltaics can be described as the next generation of photovoltaic technology. They are capable of producing electricity in urban areas that have limited land and also serve as architectural elements. Integrating photovoltaics in buildings and electronic devices requires flexibility, color tunability and efficiency as well as scalability and stability. Integrated photovoltaics must demonstrate all-around performance advantages. This is because photovoltaic performances are in a tradeoff relationship, such as transparency and efficiency. 

Thin Si Item #3747
100mm P/B (100) <0.01 ohm-cm 100um DSP Prime Grade
TTV <10um, Bow/Warp <30um, 2-Flats (We have TTV <1um. Please let us know what flatness you need)

These are great transparent solar cells (TSCs) that offer high flexibility, high transparency and color-tunable solar cell performance. TSCs have an efficiency of 7.38 and 5.52%, with average visible transparencies of 45 and 60 percent, respectively. TSCs are also more flexible due to the introduction of a periodic hole array structure. After PDMS embedding, the minimum bending radius drops to 6 mm. It further reduces to 3 mm. The numerical simulation shows that the periodic hole array structure distributes stress uniformly across the entire area, acting as a self-stress relief structure. TSCs embedded with PDMS have unprecedented flexibility and stability, even in the face of cyclic bending and heat tests up to 1000 cycles.

What Thin Silicon Wafers are Use for Surface Profilometry?

A scientist requested the following:

"I want to use silicon wafers to measure the stress of my deposited silicon oxide coatings using surface profilometry. As my current wafers show only little change in their curvature after coating with 100 nm, I was thinking about trying out thinner wafers. These are probably more sensitive to such thin coatings. My current wafers are P type with a roughness of about 2 nm and a thickness between 300 - 500 microns. Is it possible to get a quote for a 3 inch wafer with a thickness below 50 microns? The specific diameter and thickness is not too important to me, as long as they exhibit a low TTV and are thinner than my current ones. Other specifications would therefore also be perfectly fine for me."

What is Surface Profilometry?

Surface profilometry is a measurement method used to measure the topography of a surface. Surface profilometry involves measuring the topography of the sample's surface with a range of methods including contact microscopy, optical microscopy, and confocal microscopy. The AFM, a descendant of the profilometer, is a recent development in metrology and represents a step forward in surface topography. AFM uses nanoscale physical forces to determine the surface topography of a sample.

Contact Profilometry

Among the many applications of surface profilometry, the contact measurement method is the most popular. It uses a diamond-tipped stylus to measure surface topography and texture. The measurements are often made after the films have been spin-coated or magnetron sputtered. Depth profiling, which is also commonly performed with profilometers, uses these height measurements to characterize surfaces.

Optical Profilometry

The basic principle of optical profilometry for surface measurement is that the light used to illuminate the specimen must be parallel to the sample's axis. Optical measurements are not possible when the light is highly angled. Filtering is needed to remove non-linear, macro shapes, and the distance between the sample and the objective lens must be short enough to bring the surface angle into focus. However, even in these conditions, it is difficult to determine the angular distribution of the sample due to the closeness of the optics.

Diamond Stylus Profilometry

Diagonal and vertical surface variation measurements are obtained using diamond stylus profilometry. The technique requires a stylus with a tip that is moved vertically over a sample while lateral movements are performed with a diamond shim. Stylus profilometry allows the measurement of a wide range of surface characteristics, from surface roughness to the size of feature sizes. A typical profilometer can measure surface features and variations as small as one micrometer in height. The measurement process is controlled by the sampling rate and the scan speed.
