Indium Phosphide (InP), as a core material of the third-generation semiconductor, holds an irreplaceable position in high-end fields such as optical communications, millimeter-wave radar, and quantum communications due to its excellent electron mobility, wide bandgap, and superior optoelectronic properties. The surface quality of InP substrates directly determines the precision and reliability of subsequent epitaxial growth and device fabrication, with polishing and lapping processes being the critical steps in controlling this core metric. Drawing on years of practical experience in semiconductor material processing, Gizhi Electronics provides a systematic analysis of the key polishing and lapping processes for InP substrates, along with ...

In the precision manufacturing chain of the semiconductor industry, the creation of every high-performance chip relies on hundreds of process steps, from silicon purification to chip packaging. Among these, silicon wafer polishing—a critical process connecting wafer cutting and grinding with subsequent lithography and thin-film deposition—can be called the “art of surface finishing” in semiconductor manufacturing. It shapes the wafer surface with nanometer-level precision, directly determining the chip’s performance, reliability, and yield. As a company deeply rooted in the electronics field, Gizhi Electronics fully understands the core value of this process. This article will delve into the technical essence of silicon ...

第三世代半導体産業が加速する今日、炭化ケイ素（SiC）は、その優れた高温耐性と高い絶縁破壊電界強度により、新エネルギー自動車用パワーデバイスや高周波通信デバイスなどのハイエンド製造分野の技術的景観を再構築している。SiC加工において重要な工程であるCMP（Chemical Mechanical Polishing：化学的機械的研磨）は、その中核となる消耗品である研磨パッドの性能に大きく依存しており、完成したデバイスの精度と信頼性を直接左右する。長い間、日本のフジボウのG804W研磨パッドは、世界のSiC CMP分野で主流の選択肢の一つであった。.

CMPプロセスを解き明かす：光学部品加工の分野において、化学的機械研磨（CMP）は高精度の表面平坦化を実現する中核技術です。化学的腐食と機械的研磨の相乗効果により、光学ガラスの精密加工を実現します。CMPプロセスの本質は、化学的作用と機械的作用の相乗効果にある。研磨スラリーに含まれる化学試薬がまずガラス表面と反応し、除去しやすい軟化層を形成します。この化学的前処理により、その後の機械的研磨の基礎が築かれ、軟化層がガラス表面を傷つけることなく容易に除去できるようになります。.
