Product portfolio

Advanced packaging – RDL and µ-Via plating

Latest packaging technologies such as FOWLP and FC-CSP require a variety of plating solutions for different structures. Fine line RDL allows the electrical extension within the plane and are hence crucial to enable heterogeneous integration.

  • DZٱ® Cu UF3: high purity Cu process for the deposition of RDL & µ-via of highest reliabilities.
  • Promobond® AP2: adhesion promoter for next generation packaging.

Advanced packaging – Pillar plating and soldering

Latest packaging technologies such as FOWLP and FC-CSP require a variety of plating solutions for different structures. Pillars and solderbumps are used for interface interconnection and are hence crucial to enable heterogeneous integration.

  • DZٱ® Cu UF 5: high-speed process for Cu pillar plating with outstanding uniformities, high purity and full shape control.
  • DZٱ®: all liquid process for effective Ni barrier layer plating.
  • DZٱ®Դ: highly uniform and reliable tin silver process for solder applications.
  • DZٱ®: process for highly uniform, pure tin solder depot plating.

ENEPIG plating - pad metallization and RDL housing

Wire bonding and soldering often require under bump metallization (UBM) for highly reliable joint formation. Our ݱԴDZٱ® product suite allows the deposition of hard, corrosion-free, and stress-minimized metal stacks to protect underlying active structures and provide a robust, stable, and low-resistance solder joint connection to the IC substrate.

  • ݱԴDZٱ®: processes for low- to mid Pd and high-temperature electroless Ni plating.
  • ݱԴDZٱ®ʻ: electroless deposition process of pure, highly reliable Pd.
  • ݱԴDZٱ®: cyanide-free and cyanide-based immersion and autocatalytic Au processes.

Interconnect metallization solutions for logic, memory and power ICs

Next generation interconnect technologies demand extreme performance of wet metallization processes which are compatible with extremely thin seed layers for copper damascene BEOL interconnects and able to void-free fill pre-plate openings for both copper and cobalt interconnects.

Everplate® 2XT: high performance additive suite capable of filling advanced damascene Cu technology nodes.

Double sided metallization for power chips, e.g. IGBT, MOSFETS...

Modern IGBTs and power MOSFETs require metallization on both sides of a wafer. The standard way of sequentially plating first front and then backside often struggles with stress and warpage issues during wafer processing. Thin wafers, needed to embed dies in power packages, are especially prone to this effect. What we need is an effective stress and warpage reduction during wafer processing.

ѳܱپʱٱ® + DZٱ®Ѷ2: plating equipment solution and electrolytical deposition Cu process for simultaneous double side Cu plating with reduced process flow.
