Undoped Silicon, Can Also Be Called Intrinsic or Float Zone (FZ)
Undoped Si is pure silicon without any significant dopant throughout the wafer. Intrinsic silicon is neither n+ or P+.
We have a large selection of undoped silicon in the following grades:
- Mechanical Grade
- Test Grade
- Prime Grade
Silicon Wafers in stock from various manufacturers including opsil, ITME, and many more.
We also have:
- 100mm N/PH (100) 1.1-1.35 ohm-cm 525um SSP prime Grade Silicon
- 150mm N/Ph (111) 5-10 ohm-cm 625um SSP Prime Grade Silicon
- 200mm NPh (100) 80-120 725um SSP Prime Grade Silicon
Thinning Undoped Silicon Wafers
We can also thin our undoped silicon wafers. In some cases 10 micron thick is possible. And we can deposit thermal oxide, nitride and thin films.
Other Semiconductor Services that we provide include:
- Thermal Oxide (Wet and Dry) up to 10um.
- Silicon Nitride (SiN) (LPCVD and PECVD)
- Vacuum Evaporation Pt, Ru, Pd, Au, Ag, Co, Ti, Cu, Al, Ta, and Ni with thickness ranging from 10nm to 2000nm
- Metal Sputtering includes single layer and/or the combination of the following elements: Ta, TaN, Cu, Ti, TiN, Al, Al-Si-Cu, Al-Cu, Al-Si, TiW, W, WN, WSi, and Cr.
- Oxide Strip & Clean used to remove particles and contamination. We ensure cleanliness of wafers after cleaning by checking particles using near UV lamps.
- Copper Plating available for 200mm and 300mm wafers with thickness ranging between 0.3 microns and 20 microns. We have 1.5um Cu plated wafers in our inventory.
- Thick Resist Patterning offers customers thick dry resist film patterning on UBM (Under Bump metal)
- Photoresist coating ranging from 0.7um to 40um thick photoresist depending upon the photoresist in use. We have some photoresists formulated for broadband, i-Line, and Polyimide in our inventory.
