As China pushes for self-sufficiency in semiconductor technology, domestic manufacturers are striving to produce advanced ceramic heaters. Ceramic heaters are critical components in chip-making equipment. They ensure precise temperature control during key semiconductor manufacturing processes, making them indispensable in modern fabs.     Why Ceramic Heaters Matter in Semiconductor Manufacturing?  In semiconductor production, wafers undergo processes such as thin-film deposition (CVD, PECVD, ALD) and etching, which require extremely precise and uniform heating. Traditional metal heaters face limitations at high temperatures (above 500  ° C) due to thermal expansion and risks of particle contamination.     Performance Comparison: Aluminum Nitride (AlN) Heaters vs. Aluminum Heaters   No Item Al Heater  AIN Heater 1 Operation Temp R.T ~ 450  ° C (Max)  R.T~800℃ 2 Melting Point 660.25℃  1800  ° C (Sintering Temp.) 3 Thermal Conduct...

  Mass spectrometers are utilized in various industrial, environmental, and clinical applications to detect trace amounts of chemicals. This technique heats the ionized sample before it enters the mass spectrometer. Traditional heating methods include using box or cable heaters to heat metal components, which in turn conduct the heat to a flow of high-purity inert gas.   Design requirements For a mass spectrometer to achieve high detection sensitivity, it must be able to achieve most of the analyte level resolution; therefore, it must use a contamination-free heat source. In addition, the competitive demand for instrument design to reduce size and complexity while still enhancing sensitivity is also being challenged.     Solution Ceramic heaters are preferred for ion sources because of their chemical compatibility, low porosity, and fine surface finish to reduce the likelihood of contamination. In addition, it has a 400 ° C (752 ° F) function, which can meet the perf...

The Molybdenum/Manganese metallization developed the technology on   Ceramic-to-metal brazed   assembly, which provides high mechanical strength and good electrical insulation. At the very beginning, it was used in vacuum electronic devices, gradually applied to semiconductors, integrated circuits, electric light sources, high-energy physics, aerospace, chemical industry, metallurgy, instrumentation, machinery manufacturing, and other industrial fields.   So how to choose a material becomes more and more critical for good vacuum brazing. Here we’re mainly discussing about 3 different types of materials that will be used for ceramic-to-metal. Ceramic Al2O3 BeO BN AlN Metala Kovar alloy OFC Stainless steel Mild steel Solder Ag Ag-Cu Cu AU-Cu Au-Ni   The Ceramic materials are required to be high-temperature stabilized and good thermal expansion coefficient. INNOVACERA applies mostly the Al2O3. Since ceramics will not be directly wetted, whi...
