iamond is well-known for its extreme hardness, high- optical transparency, high thermal conductivity, and great chemical
stability. In spite of all these excellent properties, diamond has largely been absent in optical applications due to the
difficulty in fabricating high quality diamond thin films at lower substrate temperatures cost efficiently. Pioneering work on
low temperature, high quality diamond deposition methods by AKHAN semiconductor Inc. has opened doors for the use
of diamond in a wide variety of optical applications. Nanocrystalline diamond (NCD) coatings with grain size of 10-100 nm
can significantly enhance the breakage, scratch performance and hydrophobicity of glass displays and lenses. In this work,
NCD thin films of 50-250 nm thickness were deposited on commercial BK7 glass and chemically hardened aluminosilicate
glass (Gorilla Glass) substrates using hot filament and microwave plasma chemical vapor deposition (HFCVD and MWCVD)
techniques under optimized substrate temperatures to avoid substrate deformation. Optical characterization work of the as
deposited NCD films was performed using ellipsometry, spectral reflectance and spectrophotometry over visible wavelengths.
Mechanical characterizationworkwas alsoperformed toobtainhardness and young’smodulus data for theNCDfilms.Measured
results demonstrate the viability of NCD as a protective coating for a broad range of optical applications. Additionally, low
temperature, high quality diamond deposition allows complementary metal oxide semiconductor (CMOS) device integration
on optical substrates opening new opportunities for the development of next-generation monolithically integrated transparent
devices and electronics.
