Why does single crystal silicon need to be rolled?
Rolling refers to the process of grinding the outer diameter of a silicon single crystal rod into a single crystal rod of the required diameter using a diamond grinding wheel, and grinding out a flat edge reference surface or positioning groove of the single crystal rod. The outer diameter surfac...Read more -

Control of radial resistivity uniformity during crystal pulling
The main reasons affecting the uniformity of radial resistivity of single crystals are the flatness of the solid-liquid interface and the small plane effect during crystal growth The influence of the flatness of the solid-liquid interface During crystal growth, if the melt is stirred evenly, the...Read more -
Why can magnetic field single crystal furnace improve the quality of single crystal
Since crucible is used as container and there is convection inside, as the size of generated single crystal increases, heat convection and temperature gradient uniformity become more difficult to control. By adding magnetic field to make the conductive melt act on Lorentz force, convection can be...Read more -
Rapid growth of SiC single crystals using CVD-SiC bulk source by sublimation method
Rapid Growth of SiC Single Crystal Using CVD-SiC Bulk Source via Sublimation MethodBy using recycled CVD-SiC blocks as the SiC source, SiC crystals were successfully grown at a rate of 1.46 mm/h through the PVT method. The grown crystal’s micropipe and dislocation densities indicate that de...Read more -
Optimized and Translated Content on Silicon Carbide Epitaxial Growth Equipment
Silicon carbide (SiC) substrates have numerous defects that prevent direct processing. To create chip wafers, a specific single-crystal film must be grown on the SiC substrate through an epitaxial process. This film is known as the epitaxial layer. Nearly all SiC devices are realized on epitaxial...Read more -
