MdMaruful,
from
Bangladesh. This year March 2022, I
obtained Doctor of Philosophy inengineering from Interdisciplinary
Faculty of Science and Engineering at
Shimane University. Currently, I am
working at ASM Japan as a Process Engineer(R&D). During my master's program, I
realized that I enjoy conducting research andfind this job path to be highly appealing. It wasappealing to be able to devote several years tomy research topic and look into potential
answers to a particular research problem. I
believed that I would have enough time tomake real progress in that field of study. It wassimultaneously really uplifting, motivational,
and motivating me. That is the reason why I
chose to pursue a PhD. I felt the need toactually look for solutions to the problems thesemiconductor industry is currently having.
That was my main motivation. At thebeginning of my PhD, I didn’t know that I
would stay in academia, mostly because mybackground was in engineering and I like to dopractical stuff as you might know. That’s whyI never thought I will be an associate professor
or an editor. I just wanted to solve challenges
and solve problems.
The content/theme of research is “ZnO
Nanoparticle-based Thin Film Transistors(TFT)”. ZnO nanoparticles (NPs) based
devices are innovative technologies todevelop the new generation low-cost TFTs for
its good properties and broaden selectivity.
The technology for the NPs based TFTs isrelatively simple, compared with traditional
TFT fabrication. Thin-film transistors are thebasis of the extraordinary development of flat
screens that equip all present computers, TVs,
smartphones, and generally all the current
displays. the goal of the research is to fabricate
TFTs with low cost and good properties bymyself using n-type and p-type ZnO NP layers
and to improve the TFT performance based on
the understanding of the career conduction
mechanism. To enhance the progress of TFT
performance Ga doping and thermal annealing(at a higher temperature) carried out andsuccessfully achieved low resistive ZnO NPlayer.

In addition to my academic work, I liketo volunteer and engage in recreational
activities. I learned a lot about academics andJapanese culture at the University and fromengaging with locals during my five years ofeducation at Shimane University. I learned
Japanese as much as I could in order to better
comprehend Japanese culture and to utilize
my knowledge in my future career.
I choose the semiconductor industry
because I was attracted to the fact that it is
the crystallization of human wisdom and thattechnology changes very quickly. A variety
of technologies are used in semiconductor
manufacturing equipment, and they are thecrystallizationofscience,including
mechanics, electricity, electronics, chemistry,and information. Before completion of mydoctoral course, I planned to find a job at aprestigious research institute or worldfamoussemiconductor
manufacturing
company specializing in analysis andevaluation. The fields and themes I deal with
were similar to what I have been doing until
now, so I hope that I have the skills andinsights to meet the customer’s expectations.
I hope that I will be able to play an activerole as a person who can exercise one’sstrength and judgment. Until now, I havecontinued my research in Semiconductor
industry, which has direct impact on society.
I would like to make use of it and contributeto society.
