AbstractThe phosphorus doped polycrystalline silicon thin films were grown by Electron Cyclotron Resonance Chemical Vapor Deposition (ECR-CVD) at 250°C. The doping gas PH3 was in-situ added with SiH4 gas during the films deposition. All films were deposited with 90% hydrogen dilution ratio. The resistivity of the films is varied from 0.2 to 7Ω-cm and decrease as the PH3/SiH4 gas ratio increase from (3/100 to 7/100). From the SIMS data, the doping concentration is all about 1020cm-3. The activation energy is decreased from 0.35 eV to 0.12 eV as the dopant concentration increased from 0.8×10 20cm-3 to 4.7×10 20cm-3. From the Hall measurements, the carrier mobility is about 2∼4 cm2/V. sec, and the carrier concentration is the 0.5∼1% of the dopant concentration. The gain boundary trap density predicted by the trapping model is about 4×l013cm” 2-2

Microstructural Studies

ABSTRACTSome typical microstructural studies of polycrystalline silicon using transmission electron microscopy (TEM) are described, including the application of this material for assisting TEM investigations themselves. Examples include oxidation and realignment of polysilicon thin films, the structure of polysilicon in EEPROM devices, polysilicon in trench capacitors and measurement of SiO2 layer thicknesses with polysilicon overlayers. It is also shown tha grain growth in heavily phosphorus doped polysilicon films can be followed by in situ heating in the TEM.
