Focusing on Efficient InP Polishing | Kousei Seimitsu Invites You to Meet in Wuxi
01 Four Core Products Debut at the Indium Phosphide Exhibition
As Indium Phosphide (InP) materials are increasingly applied in high-speed optical communications, optical chips, and compound semiconductor fields, the lapping and polishing processes place higher demands on processing efficiency, surface quality, process stability, and consumable lifespan.
At this Wuxi exhibition, BOSI Kousei Seimitsu Technology Co., Ltd. will prominently display four core products for the InP material polishing process, providing customers with comprehensive solutions from rough polishing and backside polishing processes, fine polishing, to polishing pad selection.
02 KSTP-IP80 Series Alumina Polishing Slurry
Efficient rough polishing and backside polishing, balancing removal efficiency and surface quality
The KSTP-IP80 series is an alumina polishing slurry independently developed by Kousei Seimitsu for rough polishing and backside polishing processes of materials such as InP.
The product uses nano-grade alumina and can achieve high material removal efficiency while ensuring processing surface quality. According to existing test results, the maximum removal amount can reach about 4μm/min, helping to shorten rough polishing and backside polishing processing time and improve overall production efficiency.

03 KSTP-SP20 Silica Polishing Slurry
Optimized surface quality, meeting fine polishing needs
KSTP-SP20 is a silica polishing slurry independently developed by Kousei Seimitsu, mainly applied to the fine polishing process of materials such as InP.
The product uses nano-grade silica and can achieve good polishing surface results, suitable for fine polishing or surface optimization processes after rough polishing. It must be used together with the A agent.
