1. Manufacturing Process

Meeting dimensional requirements is central to producing the Magnesium Aluminate Crystal Substrate (111) 10x10x0.5 mm SSP with consistency. Manufacturers employ a controlled crystal growth method, using fusion or Czochralski techniques, to ensure the spinel lattice is uniform at the atomic level. By fine-tuning temperatures, rotation speeds, and cooling parameters, engineers shape the crystalline structure into wafers with minimal internal defects. This approach helps achieve the precise thickness of 0.5 mm, vital for maintaining substrate strength and stability in various commercial and industrial applications.

Inspecting the grown crystals involves metrology steps, such as optical microscopy and surface checks, before slicing the boules into rectangular wafers. Pelletising processes may eliminate rough edges and reduce the risk of fractures. Ultimately, a polishing sequence enhances surface smoothness, leading to single-side polished substrates suitable for deposition of thin films or other complex layers. Such manufacturing oversight guarantees each substrate offers thermal stability, uniform thickness, and low residual stress, highly valued in instrumentation and sensor technologies.
