Overview

JNB makes support equipment and precision-machined parts for the vacuum pumps used in semiconductor manufacturing.

Its stacker systems connect vacuum pumps to facility utilities and help manage piping, noise, and vibration so that pumps run efficiently inside chip-production lines; it also supplies on-tool setting kits fitted directly to process chambers. The company operates two distinct divisions, one focused on the support equipment and one on precision-machined pump components, and is listed on KOSDAQ, South Korea's tech and small-cap exchange.
