Lapping & Polishing Aqueous Vehicles • Stable Dispersions • CMP Slurries

Water based dispersants and polishing slurries customized by application for excellent stability, high removal rates and excellent surface quality.

From semiconductor wafers and substrates to optical lenses and ceramics, achieving flat, smooth, defect-free surfaces is critical.

Lapping and polishing are some of the most complex and sensitive process steps in precision manufacturing. Whether you're planarizing a silicon wafer or polishing sapphire optics, your slurry system must deliver consistent material removal and defect-free finishes—without damaging fragile materials or overcomplicating post-process cleaning.

Even slight instability in a slurry system can result in increased defectivity, yield loss, and costly downtime.

  • Chemical compatibility with a wide range of materials, including SiC, GaAs, InP, sapphire, and high-index glass
  • Stable dispersion of abrasive particles to prevent sedimentation, scratching, or non-uniform removal
  • High removal rates while meeting tight flatness and surface roughness targets
  • Environmentally friendly water based, biodegradable and low maintenance chemistries
  • Low cost of use due to highly concentrated formulations
  • Tool and process variability, which requires tunable viscosity, film strength, and surfactant behavior

Intersurface Dynamics delivers water-based slurries, vehicles, and additives engineered to meet the most demanding lapping and polishing requirements—while providing chemical stability, material compatibility, and process efficiency.

IDI offers a portfolio of aqueous slurries, slurry vehicles, and additives for both loose and fixed abrasive polishing. Each is optimized by application to support stable particle suspension, efficient material removal, and defect minimization across a wide range of substrates and equipment platforms.

Suspension-Type Lapping Vehicles

  • Viscous, biodegradable polymer/surfactant blends that fully suspend abrasives like alumina and silica
  • Engineered for semiconductor substrates, ceramics, and optics
  • Maintain suspension and dispersion over long intervals, reducing the need for constant mixing

Our suspension-type lapping slurries, including those in the Vector HTS Series, are biodegradable, viscous polymer/surfactant blends designed to disperse and suspend abrasives like aluminum oxide and silicon dioxide when mixed with de-ionized water. Engineered for the lapping of semiconductor substrates, these slurries fully disperse and suspend abrasive material for extended periods of time with relatively little change in physical or chemical characteristics. Designed for use on all types of lapping plates and tool-sets.

Products within the HTS series have varied chemical and physical properties, resulting in differences in wetting, film strength and viscosity. This allows the formulation to be optimized for any application.

Key Products:
Vector HTS Series
Challenge 550 Series
Challenge 543-HT

Diamond Polishing Systems

  • Thixotropic vehicles for dispersing diamond abrasives, ideal for hard crystalline materials like SiC, sapphire, and GaN
  • Available as base vehicles or ready-to-use slurries with diamond powder
  • Deliver reduced scratching, improved cut rate, and flatter surfaces—while simplifying post-lap cleanup

Benefits of Vector TXT and CE Diamond slurries include flatter wafers with reduced damage, cut-rate enhancement, reduced scratching, reduced abrasive usage, stain prevention and more consistent results. Additionally, because the products are water soluble, post-lap cleaning is much easier. Lapping vehicles are also compatible with all other Intersurface Dynamics products.
