Silicon is susceptible to fatigue even under inert environment, although it has been believed not to be. This paper presents a brand-new image of the fatigue behavior of silicon obtained using the microtensile method. It is estimated that 25% of polysilicon specimens and 34% of single-crystal silicon will break in about 100 years in a nitrogen atmosphere at room temperature, when subjected to a fatigue...
Silicon wafers become semitransparent at room temperature and at wavelengths more than 1.1 mum. Silicon wafers with an oxide film layer are also semitransparent because the extinction coefficient of the film optical constants is negligible at visible and infrared wavelengths. We experimentally studied optical properties such as emissivity, reflectivity and transmissivity of silicon wafers with and...
