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 ...
Alors que l'industrie des semi-conducteurs de troisième génération accélère son itération aujourd'hui, le carbure de silicium (SiC), en tant que matériau de base, redessine le paysage technologique des domaines de fabrication haut de gamme tels que les dispositifs d'alimentation des véhicules à énergie nouvelle et les dispositifs de communication à haute fréquence, grâce à son excellente résistance aux hautes températures et à son champ de rupture élevé. Le polissage mécano-chimique (CMP), un processus critique dans le traitement du SiC, dépend fortement de la performance de son principal consommable, le tampon de polissage, qui détermine directement la précision et la fiabilité des dispositifs finis. Depuis longtemps, le tampon de polissage G804W de Fujibo (Japon) est l'un des principaux choix dans le domaine du CMP SiC, ...
Débloquer le processus CMP : Principes et avantages Dans le domaine du traitement des composants optiques, le polissage chimico-mécanique (CMP) est une technologie de base permettant d'obtenir une planarisation de surface de haute précision. Grâce aux effets synergiques de la corrosion chimique et du meulage mécanique, il permet d'usiner avec précision le verre optique. L'essence du processus CMP réside dans la synergie entre les actions chimiques et mécaniques. Les réactifs chimiques contenus dans la suspension de polissage réagissent d'abord avec la surface du verre pour former une couche ramollie facile à enlever. Ce prétraitement chimique jette les bases du meulage mécanique ultérieur, en veillant à ce que la couche ramollie soit facile à enlever sans endommager la surface du verre.
