Summary

"Expertise in Semiconductor"

I have an expertise in semiconductor physics, devices, and process. In order to develop practical skills, I conducted "designing a photomask','semiconductor process practice','analyzing through 4-point probe equipment', etc.

"Communication and collaborative skills"

Through diverse team project experience, I realized the leaders plays a crucial role in 'gathering and supporting teams by inspiring passion and motivation'.

Furthermore, Various experience of interacting with students while working as a feedback teacher at math academy will be valuable in responding to diverse customer demands and facilitating seamless collaboration upon joining ONTO innovation Korea.


To sum up, I am ready to commit to delivering effective ONTO innovation Korea's solutions and building a reputation as a 'trustworthy engineer' through strong work ethics and responsibility.

My goal at ONTO innovation Korea is not only to meet our client’s requirements but also to take the lead in organizing regular seminars with fellow engineers to gain insights into the market dynamics. Additionally, I will work closely with our headquarters to deliver the clients’ desired portfolio.

Work History

Intern Engineer

Emerging Semiconductor Devices LAB
02.2022 - 09.2023

Thin-film transistors TCAD Simulation (Semiconductor Process & Device Modeling)

: I have experience in researching

semiconductor devices using Silvaco TCAD.
Especially, I took a role in redesigning the devices' structures or parameters to boost their performances like On/Off current ratio, etc.


1) Device Structure: Redesign the conventional single-gate structure to dual-gate structure, improving the on-off current ratio by 7.65 times.

2) Analysis by scaling devices:
By reducing the dimensions of the device and extracting I-V and C-V characteristics, the Vt roll-off characteristics and the failure point where the device breaks down were identified.

3) Density Of States parameter study: To analyze the effect of the parameters, a total of 56 combinations of models were designed to analyze the electrical characteristics and organize them.

4) Device Fitting: To match the I-V measured value of the actual device studied in Samsung Display and TCAD simulation I-V value, the Device Physics parameter was changed to optimize the error to within 7%.
