How to Prepare an RFQ for Custom Ceramic Components

Custom ceramic components can include rings, plates, tubes, chucks, support parts and other shapes made to fit a specific machine or process. A clear request for quotation helps suppliers assess manufacturability, identify missing information and quote the correct inspection scope. Start with the part drawing. A 2D drawing should show all critical dimensions, tolerances, hole […]

Why 99.9% Alumina Is Not Enough: Microstructure Is Becoming the Real Specification for Semiconductor Ceramics

“99.9% alumina” is a common ceramic specification. For semiconductor equipment, however, this number does not tell the whole story. Two ceramic components can both contain 99.9% Al₂O₃ and still behave very differently inside a plasma-processing chamber. The reason is microstructure. Porosity, grain size, grain-boundary chemistry and sintering history can influence erosion, contamination and particle generation

YOF Ceramic Coatings for Semiconductor Etch Chambers: Why Fluorine-Containing Surfaces Are Gaining Attention

Advanced semiconductor etching requires increasingly aggressive plasma environments. Fluorine-containing gases are widely used to etch materials such as silicon oxide, silicon nitride and other semiconductor films. The same plasma that removes material from the wafer also attacks the chamber. This creates a major materials challenge. Chamber-facing components must survive chemical attack and energetic ion bombardment
