Young Jun Tak et al. had used a simultaneous DUV and thermal treatment to anneal their sputtered indium-gallium-zinc oxide channel layers [19] and hafnium oxide gate dielectric films [20].
The bandgaps of our samples are larger than (3.00 eV) which was reported by Goldenberg et al.[9], but within the same range of the value (3.9 eV) reported by Frye et al.[23] for their annealed samples.
This breakdown value is slightly less than 0.85 MV/cm obtained by Radhakrishnan et al. [12] for STO films annealed at 500oC.
Oluwabi et.al. [16] reported that DUV activation enhances the quality of their ZrO films by increasing the number of M–O bonds and decreasing the number of oxygen vacancies.

Puertas et al. presented mathematical models for electric discharge machining of WC-Co, SiC and conductive ceramics on the basis of experiment designing techniques.
Khoshkish et al. studied the effects of electrode tool materials and machining input parameters (such as: current, pulse-on time) on AISI D3 EDM characteristic, by analysis of variance and experiments designing techniques.
