Structural Ceramics for Semiconductor Manufacturing: Materials, Properties and Key Applications

Semiconductor manufacturing equipment operates under some of the most demanding conditions found in modern industrial production. Components may be exposed to high temperatures, plasma, corrosive gases, vacuum environments, rapid thermal cycling, aggressive cleaning processes and extremely strict contamination requirements. Under these conditions, conventional metals and polymers are not always suitable. This is why structural ceramics

Ceramic Electrical Conductivity Guide: Al2O3, AlN, SiC and ESD-Safe Ceramics

Ceramics are often described as electrical insulators, but this description is incomplete. In semiconductor equipment, electronics manufacturing, vacuum systems, wafer handling, and precision automation, ceramic components may be required to perform very different electrical functions. Some components must provide extremely high electrical insulation. Others need controlled semiconductive behavior to prevent static charge accumulation. Certain silicon

SiC Wafer Boat Cleaning and Contamination Control: Particles, Metals and Service Life

Silicon carbide wafer boats are widely used in semiconductor thermal processing because of their high-temperature stability, mechanical strength, chemical resistance, and relatively low particle generation. They are commonly found in oxidation, diffusion, LPCVD, annealing, and other furnace processes where wafers must be securely supported at elevated temperatures. However, even a high-quality SiC wafer boat can

Wafer Boat Slot Geometry Guide: V-Groove, U-Groove, Contact Area and Wafer Edge Protection

Wafer boat performance depends on more than the boat material, wafer capacity and overall dimensions. The geometry of each wafer slot directly affects wafer positioning, edge contact, loading stability, thermal movement and the risk of chipping or particle generation. A slot that is too narrow may grip the wafer edge too tightly. A slot that

Comment définir les caractéristiques d'un porte-plaquettes personnalisé : diamètre des plaquettes, espacement des emplacements, capacité et tolérances

A custom wafer boat must do more than hold a group of wafers. It must maintain consistent wafer spacing, fit the processing equipment, withstand repeated thermal cycles and avoid introducing particles or metallic contamination. Small dimensional errors can create serious operating problems. Incorrect slot pitch may interfere with robotic loading, insufficient clearance can damage wafer
