Technical Dossier
The JUSUNG Engineering 15KLD02Z Chamber Unit is a precision process module deployed in atomic layer deposition (ALD) and chemical vapor deposition (CVD) semiconductor fabrication equipment. JUSUNG Engineering, headquartered in Gwangmyeong, South Korea, is a Tier-1 OEM supplying process chambers and related sub-assemblies to leading wafer fabs across East Asia, Southeast Asia, and Europe. The 15KLD02Z chamber unit and its associated part numbers — 30895004, P30895004, and 4022.437.11211 — represent a critical mechanical and process interface component within JUSUNG's cluster tool architecture.
These modules are installed in high-volume production environments including DRAM fabs, NAND flash facilities, and logic foundries. Their role in maintaining process gas isolation, substrate temperature uniformity, and vacuum integrity makes them a long-lifecycle spare part with sustained global demand well beyond the original equipment warranty period.
JUSUNG's chamber unit design has evolved across multiple equipment generations. Early-generation JUSUNG ALD systems (circa 2005–2012) used single-wafer chamber configurations with discrete mechanical sealing assemblies. The 15KLD02Z series reflects a mid-to-late generation design incorporating integrated gas distribution, improved thermal management interfaces, and standardized bolt patterns compatible with JUSUNG's Eureka and Covanta platform cluster tools.
Cross-generation compatibility is a known engineering constraint: the 15KLD02Z is dimensionally and functionally specific to its designated platform generation. Substitution with earlier or later chamber unit revisions requires engineering validation. DriveKNMS maintains cross-reference records for superseded and successor part numbers to support accurate sourcing decisions.
As JUSUNG has transitioned portions of its product line to next-generation ALD platforms, the 15KLD02Z and its associated assemblies have entered a mature/end-of-active-production phase. Long-term maintenance support — including refurbished, tested-used, and new-old-stock (NOS) units — is the primary supply channel for this part family.
The following SKUs represent the documented part number ecosystem associated with JUSUNG chamber unit assemblies, process module sub-components, and related spare parts within the same equipment generation. Each entry reflects a distinct functional role within the chamber or cluster tool architecture.

DriveKNMS operates as a specialist distributor for semiconductor equipment spare parts with a focus on JUSUNG Engineering modules that are no longer available through standard OEM channels. For the 15KLD02Z chamber unit and associated assemblies, DriveKNMS maintains inventory sourced from:
All sourced units are cross-referenced against JUSUNG's internal part number revision history. Where a direct replacement is unavailable, DriveKNMS provides engineering-validated alternative part numbers and compatibility notes at no additional charge.
Chamber unit modules present specific inspection requirements due to their process-wetted surfaces, precision-machined sealing faces, and thermal cycling history. DriveKNMS applies the following inspection protocol to all 15KLD02Z units prior to shipment:
