Chicken feathers are considered the waste products of the poultry industry and poor disposal management couldlead to solid waste generation and environmental pollutions. Alternatively, feathers can be processed into a low-grade animal feed, but this demands water and energy. Due to environmental and sustainability concerns, this waste should be effectively managed beneficiated. This study aimed to fabricate a low dielectric composite made from methacrylated epoxidized palm oil and chicken feather for semiconductor application. Composite samples were prepared with 0 wt%, 5 wt%, 10 wt% and 15 wt% of mass feathers. Flexural and mechanical properties of the composites were investigated. Composites samples were analyzed by scanning electron microscope, and differential scanning calorimeter techniques. Results revealed that the addition of CFs significantly increase the flexural strength. SEM study revealed that the surface of CF-MEPO composite was rough and unevenly distributed. The DSC analysis demonstrated that the glass transition temperature of CF-MEPO composite increase with increasing CF content. The dielectric constant of CF-MEPO composite was decreasing with increasing of frequency, ranges from 3.56 to 4.15 at 1 MHz, making it suitable for semiconductor application. [ABSTRACT FROM AUTHOR]

The CD-SEM has been the tool of choice for the imaging and metrology of semiconductor devices for the past three decades but now, with critical dimensions at the nanometer scale, electron beam instruments can no longer deliver adequate performance. A scanning microscope using a He+ ion beam offers superior resolution and depth of field, and provides enhanced imaging contrast. Device metrology performed using ion beam imaging produces data which is comparable to or better than that from a conventional CD-SEM although there are significant differences in the experimental conditions required and in the details of image formation. The charging generated by a He+ beam, and the sample damage that it can cause, require care in operation but are not major problems. [ABSTRACT FROM AUTHOR]
