Tier-1 Semiconductor Fabrication Facility Hwaseong ZEISS AIMS32-193i DVIA-P4000 Installation Report
Contents
Overview
Tuning and vibration measurement were performed on the DVIA-P4000 installed at Tier-1 Semiconductor Fabrication Facility Hwaseong NRD Line.
Tuning and vibration measurement were conducted with the equipment installed / IDLE.
On November 10, 2025 during inspection, part of the access floor around the isolator was in contact with the isolator. Such structural interference is a factor that directly and strongly affects isolator performance.
A booth structure was connected adjacent to the equipment installed on the isolator, and strong vibration from that booth was observed continuously. Such vibration may affect isolator performance and vibration measurement results.
Before and after inspection data were compared.
Data are presented as VC curves with reference materials for vibration level assessment.

Notes:
1. VC-A/B is measured in 1/3 octave bands from 8-80 Hz, VC-C through VC-G from 1-80 Hz.
2. Detail size refers to line widths in microelectronics manufacturing or particle sizes in medical research.
