Graphite insulation in semiconductors
Jincheng Graphite, as a professional manufacturer of graphite products, provides high insulation and stability semiconductor graphite insulation materials. These materials are specially designed for chip packaging, high-frequency circuits, etc., and possess advantages such as high temperature resistance, low dielectric loss, and corrosion resistance. They are widely used in the high-end semiconductor manufacturing field.
Core Advantage
Outstanding insulation performance
Utilizing high-purity graphite base material, through vacuum impregnation process, the dielectric strength is enhanced to 10^6 V/m, ensuring zero leakage during high-frequency signal transmission and reducing the risk of chip short circuit.
Extreme environment adaptability
Through high-temperature sintering technology, the graphite insulating material can maintain stable insulation performance within the temperature range of -200℃ to 1200℃, suitable for high-temperature reflow soldering and vapor deposition processes in semiconductor packaging.
Customized processing capabilities
Supports precision processing such as laser cutting and plasma etching, meeting the customized requirements for insulation layer thickness ranging from 0.1mm to 1mm and complex geometries in chip packaging, suitable for advanced manufacturing processes of 5nm and below.
Application Scenario
Graphite insulation in semiconductors is widely used in integrated circuit packaging (such as insulation between chips and substrates), high-frequency radio frequency circuits (to prevent signal interference), and power modules (to isolate high-voltage components). Its low dielectric loss characteristic can reduce signal attenuation and improve the stability of high-frequency circuits; at the same time, its high-temperature resistance ensures that insulation does not fail during high-temperature processing, thereby guaranteeing chip yield.
