A novel approach to tool monitoring for furnace tools with dynamic recipe management

Autor: Satyajit Shinde, Garrett Szafman, Bradley Savoy, Jaana S. Rajachidambaram, Chihyun Jung, Shiladitya Chakravorty

Publikováno v: 2018 29th Annual SEMI Advanced Semiconductor Manufacturing Conference (ASMC).

In semiconductor manufacturing regular tool monitoring is essential for quality control. For the case of furnace tools tool monitoring is done by processing tool qualification wafers on tools followed with measurements on the wafers. Regular tool qua

A Branch and Bound Algorithm for Cyclic Scheduling of Timed Petri Nets

Autor: Hyun-Jung Kim, Tae-Eog Lee, Chihyun Jung

Publikováno v: IEEE Transactions on Automation Science and Engineering. 12:309-323

A timed Petri net (TPN) has been widely used for modeling, scheduling, and analyzing discrete event dynamic systems. This study examines cyclic scheduling problems of a TPN to minimize the cycle time especially for automated manufacturing systems. Ap

Steady state analysis of timed event graphs with time window constraints

Autor: Tae-Eog Lee, Chihyun Jung, Seong-Ho Park

Publikováno v: Discrete Applied Mathematics. 167:202-216

For discrete event systems, time window constraints between two events are often required to control their behavior. Such time constrained discrete event systems are found in various industrial systems such as chemical vapor deposition processes for

Scheduling Cluster Tools With Ready Time Constraints for Consecutive Small Lots

Autor: Chihyun Jung, Jun-Ho Lee, Hyun-Jung Kim, Tae-Eog Lee

Publikováno v: IEEE Transactions on Automation Science and Engineering. 10:145-159

In the semiconductor manufacturing industry, the lot size currently tends to be extremely small, even being only 5-8 wafers, whereas conventional lots have 25 identical wafers. The smaller lot size is made because customers demand extremely small lot

Development of an Adaptive Forecasting System: A Case Study of a PC Manufacturer in South Korea

Autor: Chihyun Jung, Dae-Eun Lim

Publikováno v: Sustainability; Volume 8; Issue 3; Pages: 263
Sustainability, Vol 8, Iss 3, p 263 (2016)

We present a case study of the development of an adaptive forecasting system for a leading personal computer (PC) manufacturer in South Korea. It is widely accepted that demand forecasting for products with short product life cycles (PLCs) is difficu

Cyclic Scheduling of Cluster Tools With Nonidentical Chamber Access Times Between Parallel Chambers

Autor: Tae-Eog Lee, Chihyun Jung, Yu-Ju Jung, Dae-Kyu Kim

Publikováno v: IEEE Transactions on Semiconductor Manufacturing. 25:420-431

Most cluster tool scheduling studies assume identical access times between chambers or do not discuss the impact of access times. However, the optimal scheduling rule and the cycle time can depend on the access times or physical configuration of para
