Microheaters

Kamet’s microheaters offer a heating solution in high tech processes and applications where precisely controlled temperature is required, possibly in extremely small spaces or at high temperatures. Some examples of applications include the semiconductor and aerospace industries.

Our mineral insulated (MI) microheaters are bendable and can be custom designed to fit the heaters in small environments where every nanometer counts. Furthermore, they can function reliably in environments that are extremely challenging: not only high temperatures but also  for other reasons such as: corrosion, high pressure or vacuum.

Using microheaters for small environments

Microheaters are small heaters with a mineral insulated outer layer and metal sheath. They consist of one or two wires that convert electrical energy into heat. A resistance wire is connected to a conductive wire and both are insulated with pure magnesium oxide (MgO). The MgO ensures that the heating section is insulated from environmental conditions.  They are high-powered and capable of being very precisely controlled even at temperatures of 1000°C. Other key characteristics include:

  • reliable and consistent output ensuring temperature uniformity.
  • function at a wide temperature range
  • suited to air, high pressure or vacuum
  • sheath materials provide resistance to different forms of corrosion
  • quick response rate
  • flexibility: these bendable heaters can also be coiled or cast in metal
  • extremely thin outer diameter (as small as 1 mm) means they fit in tiny, complicated spaces
  • consistent power output independent of temperature variations
  • pure and chemically stable, the magnesium oxide layer protects and ensures a long product life
  • good mechanical strength and vibration resistance
  • power efficient: heat is generated exactly where required, reducing power consumption

Microheaters are the ideal product for high tech industries such as:

Semiconductor industry

Including high-end applications such as ion implantation or vaporizer and deposition systems. They are especially important where  process stability is key such as wafer production. Microheaters can also be used in sputtering systems in which thin film layers are deposited in semiconductor devices and other nanotechnology products. Our custom made solutions integrate the mineral insulated heaters in the desired end product.
