[현장 업무에서 의사소통을 다시 한번 깨닫다] 입대전 르노자동차 협력업체에서 일할 때, 작업 현장의 소음 때문에 의사소통이 원활하지 않아 갈등이 발생한 적이 있습니다. 2살 많은 사원에게 존댓말로 작업 방법을 설명했지만 공장 내의 소음 때문에 말을 잘 듣지 못하고 처음 왔을때부터 반말을 했다고 오해가 계속 쌓여 나중에는 말싸움을 하였습니다. 이 갈등을 해결하기 위한 객관적인 증거가 필요하다고 생각했습니다. 그래서 같은 파트에서 일하던 직원이 제가 존댓말로 설명했음을 증언해주었습니다. 이후에 상급자와의 3자 대면을 통해 서로의 오해를 풀 수 있었습니다. 이 과정에서 서로의 입장을 이해하게 되었고, 소음이 많은 환경에서 원활한 의사소통의 중요성과 보다 객관적인 접근이 필요하다는걸 다시 한번 깨달았습니다. [CS 문제 해결 능력 함양을 위한 반도체 공정/설비 데이터 분석] 반도체 공정이 정상적으로 진행되는지 공정/설비 데이터 분석을 진행 했습니다. Excursion이 발생했을 때 해당 웨이퍼의 진행 이력을 분석하였습니다. ‘측정된 파라미터 값의 변화가 1% 내외이면 정상 진행되었다’라고 판단 기준을 정하고 데이터 전처리후 조건을 만족하는 가스 농도, 압력, 온도를 포함한 recipe를 선정하였습니다. 이후에 target spec을 만족하는 recipe에서 wafer 내 가장 취약한 지점을 wafer 평균값으로 전처리한 데이터를 활용하여 평균값에서 얼마나 멀어졌는지 비교하며 찾아내었습니다. 그 이후에는 target spec을 조정하여 recipe를 수정해보는 과정까지 진행하였습니다. 이러한 현장경험과 직무경험을 통해 CS엔지니어로서 풍부한 현장경험, 다른 부서와의 원만한 의사소통, 공정/설비 데이터 분석과 같은 필요한 역량을 갖추게 되었습니다. 업무를 진행하면서 다른 부서와의 의견차이로 인한 충돌이 잦을것이라 생각하고 현장 조건이 자신에게 안 맞아 작업하기 힘들수도 있을것이라 예상되지만 풍부한 현장 경험과 쌓아온 역량을 통해 발생하는 이슈들을 원만하게 해결하겠습니다.

[영문 자기소개서] 위의 국문 자기소개서를 기반으로, 본인에 대한 자기소개를 영문으로 작성하시기 바랍니다. (자유양식, 글자 수 제한없음) [An Athlete Who Loves the Sea] I grew up close to the sea from a young age. In the spring and fall, when the mudflats opened in front of my kindergarten, I would catch crabs and clams. In the summer, I would swim at the beach. In addition to this, my parents taught me various activities such as hiking and fishing, which we enjoyed together. My father also taught me baseball, which led me to dream of becoming a baseball player. Wanting to improve, I worked hard and played baseball for 10 years, but I had to give it up due to family circumstances. Nowadays, I frequently watch sports, go fishing to catch seasonal seafood, play billiards, and participate in weekly matches as a member of a futsal club. Having spent so much time engaged in outdoor activities, I found joy in experiencing a variety of things. Rather than being excellent at just one thing, I became eager to excel in many areas. This drove me to study fields I was interested in diligently, and through my outdoor activities, I developed a strong physical and mental toughness. I never hesitated to take on tough tasks, such as working in factories or doing odd jobs that others might avoid. Not only do I take part in company work, but I also form various channels of communication with my colleagues, working together to overcome challenges and share joy. I hope to maintain these relationships for a long time. [The Values of a Proactive and Responsible Life Learned as a Self-Propelled Artillery Mechanic] I served in the artillery unit in Yeoncheon, Gyeonggi-do, as a self-propelled artillery mechanic. During my time as a private, even though I had learned the names of tools and the equipment that made up the artillery during training at the Artillery School, I often forgot them during actual maintenance, which led to frequent scoldings from my transport team leader and maintenance officer. Growing up with a strong desire to “do well” in everything I did, I began to re-memorize the technical manual I received at the Artillery School. I also proactively asked my superiors and my senior for advice on the maintenance order and points of caution whenever we worked on the equipment. After each session, I took notes on the maintenance tasks and reviewed them consistently. My efforts paid off as the maintenance officer and the transport team leader began to notice and give me more opportunities. For six months, I continued to memorize and rehearse everything I recorded and, despite the difficulty, actively engaged in maintenance tasks. When I became a corporal, our transport unit achieved 3,000 accident-free days. Through discussions among the transport unit officers, my efforts were recognized, and I was awarded a battalion commander’s commendation as a representative of the maintenance crew. This experience of being acknowledged within an organization changed my goal in the military to “work even harder.” From then on, I took on the role of the self-propelled artillery maintenance team leader, guiding the drivers under my command, conducting regular equipment checks, and reporting them until I was discharged. I also made sure to pass on all my know-how to my junior drivers. As a result, the officers recognized my expertise in equipment management, and they granted various benefits to the maintenance team. Until the day I was discharged, I was known as “the best mechanic” by my fellow soldiers and officers, and I completed my military service successfully. I was discharged in October, and shortly afterward, I received a job offer from a Renault car parts supplier, where I worked on manufacturing radiators. Thanks to the skills I had acquired in the military, such as tool usage, I quickly adapted to the work. My supervisor noticed my eagerness to learn and my dedication to coming to work every day, telling me, “We’ve got a good one here.” Such words motivated me to work even harder. Until my last day, I diligently completed all my tasks with a sense of responsibility while building good relationships with my colleagues. Before I left, my supervisor called me aside and said, “Thank you for working hard and doing well. If you’re ever interested in working at the manufacturing headquarters, give me a call.” This was an opportunity I didn’t want to miss, so I decided to take on a new challenge and reached out to him. After interviewing for the manufacturing headquarters, I worked in the air filter production line until I returned to school. During this time, I also got along well with new employees, completing my time at the company on a high note. My military service taught me the importance of being proactive and responsible. I realized that having these qualities is the best way to be recognized within an organization. When I join a company, I will actively participate in my assigned tasks, work on improving my skills, communicate smoothly with others, and carry out my responsibilities with dedication. [Shift Work Experience at Renault] I believe that having diverse hands-on experiences and a wide range of studies is a competitive advantage. Particularly, my various on-site work experiences at Renault serve as a key factor that differentiates me from others. Before my military service, I worked in various departments, including vehicle inspection, packaging, and transportation. After my discharge, I was involved in seat manufacturing, air filter production, and radiator production, gaining hands-on experience in nearly every aspect of vehicle manufacturing. Through these experiences, I developed the ability to resolve issues related to equipment malfunctions and component defects, as well as the ability to adapt flexibly to on-site conditions. I was able to familiarize myself with these tasks and on-site issues within just two days, earning positive feedback from my supervisors. [Implementing MATLAB Programs Using ChatGPT and Python] I frequently used ChatGPT when taking courses that required coding. When I encountered errors or the desired output didn’t come out, I often captured the error messages or result windows and repeatedly uploaded them to get help. As the process became more involved, the accuracy of the results tended to decrease. As a result, I decided to make it my thesis topic to develop a program that automatically fixes and re-runs the code until no errors occur when a prompt is entered in the early stages. When an error occurs, the code is returned to OpenAI to automatically correct the errors and return a new version of the code. However, I encountered an issue where the output varied despite no changes in the prompt. To address this, I studied prompt engineering further and modified the code to use better LLMs (Large Language Models). On the day of the presentation, I demonstrated changes in the output for three sample prompts in real time and received an A+ grade. Even though the LLM field was unfamiliar to me, the process of getting closer to the desired output by continuously modifying prompts and code was enjoyable, and it sparked my curiosity to explore further applications of LLMs. I went on to develop a plugin for data analysis using LLMs and have continued working on improving its performance. I believe that the ability to utilize artificial intelligence will become even more important in the future. I plan to apply the skills I’ve gained in AI to contribute to solving equipment problems by identifying their root causes. [A Broad Study Spectrum Spanning from Device to Process] In the “Semiconductor Device Design” course, I served as the project leader. Through TCAD, I directly set parameters from scratch and designed BJT, CMOS, DRAM, TFET, Flash memory, IGBT, and more, sharing the data to collaborate with team members in designing optimal devices. To make the CMOS noise margin equal to VDD/2, I set the device widths of PMOS and NMOS according to the mobility ratio to ensure latency-free operation. Additionally, to lower the IGBT operating voltage to 1V, I adjusted the trench structure's depth and, using the I-V curve, designed an IGBT with an optimal depth of 0.5 μm. Through this diverse design experience, I gained insights into using design tools and understanding device operation characteristics that I hadn’t known before. For example, by adding pocket doping to TFET, I confirmed that the switching operation occurred at a lower threshold voltage than before. In the “Semiconductor Engineering” course, I also led the NAND gate IC Reverse Engineering project, utilizing the data from the CMOS device simulations in the Semiconductor Device Design course. I determined the width ratio of PMOS and NMOS based on mobility values and designed a multifinger mask. To enhance the uniformity of the numerous multifinger CMOS, I selected the LPCVD oxidation method. The ion implantation and etching processes were designed using the data from Semiconductor Device Design, and we created the device in DIP form. Collaborating with others in designing the process improved my teamwork skills. By successfully completing the project, we earned high marks for the assignment.
