Hello, I'm Bae Minho, who wants to become a semiconductor process engineer. I want to work at a company called DB Hi-Tech the most, and I want to apply for a job in mass production development at that company. I haven't been able to focus on my grades, and I have never had any interview experience, so I want to experience an interview like a real one. Also, because my mentor used to work in the HR department at Samsung Electronics, one of the companies I want to go to, I want to indirectly experience the interview process at Samsung through that connection. When I saw your resume and self-introduction, I was really worried about what to ask this person. Because I thought that without this self-introduction, there is no accurate understanding of the job position, and that's why there were various mixed points. So, it was quite a troubling case. Can I ask you for a brief self-introduction? Hello.

My name is Bae Min-ho, a job applicant for semiconductor process development. I would like to summarize my introduction in two aspects. First, I am a candidate who is very interested in the semiconductor industry. I have been reading news related to the semiconductor industry every day, and I have a strong interest in semiconductor processes. I have completed two semiconductor process internships, online semiconductor education, and recently gained additional experience in semiconductor process practice. Secondly, I am a candidate preparing for future growth. Through practice, I learned that humans are the biggest source of contamination in clean rooms where semiconductor processes take place. Therefore, I felt that the use of artificial intelligence and task automation is inevitable in the semiconductor industry. I have experience in module control programming from my graduation project, which I believe gives me a strength in this area.

I will strive to become a talent who can contribute to the growth of the company by steadily building expertise in semiconductors, semiconductor processes, and programming, and integrating these two. I heard your self-introduction well. You mentioned that you read the news every day. What news did you read today? Today, I read the news about the semiconductor chip alliance. Would you like to tell us about the content? I am aware that the United States and China are currently in conflict over the semiconductor industry. The country of South Korea holds a crucial technology called Foundry in the semiconductor industry, which the United States possesses, and China is a major customer for semiconductors in Korea. Therefore, both sides are in a situation where they cannot take sides. That's why the United States created a 10-member alliance to exclude China from the semiconductor industry.

In South Korea, there is a concern about whether to join the zipper alliance with the United States and stick together in the semiconductor industry. They are contemplating whether to continue selling semiconductors to Chinese consumers without joining the alliance. You mentioned that through some practical training, it was learned that people produce the most pollutants in the line for semiconductor production. Could you please explain this part in more detail? I completed a semiconductor process practical training at Inha University. The research labs operated by Inha University consist of clean rooms. There are clean rooms with extremely low levels of pollutants and clean rooms where a small amount of pollutants is allowed. During the explanation about these clean rooms, it was pointed out that people could introduce pollutants like eyelashes, hair, and such.

When the oils coming from a person's skin evaporate, these tiny particles can float in the air, and this process occurs in the semiconductor industry. Due to the contaminants, the yield of semiconductor wafers may decrease. Through experiments, I learned that humans are the main source of contaminants. So, is it okay if humans are not involved in the production line? If humans are not present and do not enter the production line, the possibility of contaminants interfering with the semiconductor process decreases, which could lead to an improvement in wafer yield. However, even if humans are not involved, it cannot be guaranteed that all wafers will come out without any issues. This is because there are variations in equipment, and depending on the equipment, dust or small particles may still occur. So, in your opinion, what do you think about this situation?

Particles exert influence within a strong force. Do you know what the overall ratio is? In the case of humans, it was learned that in a clean room, if there are contaminants, humans are responsible for about 75% of the contamination. So, if the cause of particles in the cream is 100, 75 refers to humans, and the remaining 25 is due to variations in equipment, leading to errors caused by such equipment deviations, resulting in dust or small particles. You mentioned that your current job function is in production development. Please explain a bit as you seem to understand the job function. First, in the semiconductor R&D center, we design semiconductor circuits and processes, then proceed with semiconductor processes based on the design.

When designing semiconductors and determining the yield to a certain extent in the semiconductor process, if you want to know how much yield can be achieved, you hand it over to the mass production team. The mass production development team is responsible for figuring out how to produce more of these circuit-integrated semiconductors by changing the process. In carrying out these support tasks, what do you think is the most important aspect? I believe it is the spirit of challenge. I think it is a job where you need to constantly change and try different processes in order to increase productivity even a little bit, and to achieve growth and results. So, in the current mass production development, when you continue to make changes with a challenging spirit, who bears the risks associated with those changes? The company bears and manages the risks that arise from changing those conditions. As far as I know, the company is handling those risks. So, why does the company have to bear all those risks?

With just a little time to think, it doesn't matter what the yield is when transitioning from development to mass production. The magpie asked if you want to work at Dongbu HiTek, saying you think you can contribute by diagnosing and being able to turn yourself back. What do you think your weaknesses are? I think it's stubbornness.
