• What is silicon carbide used for?

  The main uses of silicon carbide​ are divided into three parts, one is abrasive abrasives, the other is refractory materials, and the third is casting and smelting instead of ferrosilicon. It can be said that these three types of uses account for 90% of silicon carbide. Secondly, there are major applications such as applications in the semiconductor field and applications in the photovoltaic field.

• Why use hafnium oxide in a mos versus silicon dioxide?

  Hafnium dioxide (HfO2) is an oxide with a relatively high dielectric constant. As a dielectric material, HfO2 is considered as an alternative field effect due to its high dielectric constant value (~20), large band gap (~5.5eV), and good stability on silicon substrates. Ideal material for conventional SiO2 dielectric layers in transistors.

• How to fix a damaged sputtering target?

  When our target is damaged, there are two situations. If there is only a slight crack, we can bond the target to the back plate so it can be keep up used; if the damage is serious, the target will not be used, and we need to rework one. If it is "target poisoning", we can use an intermediate frequency source or radio frequency source to beat the target for an hour or two, then take out the target, polish it with sandpaper, remove the surface pollutants, and it will be restored.
