What Does SPEG Stand For?

SPEG stands for Solid Phase Epitaxial Growth

SPEG, or Solid Phase Epitaxial Growth, is a materials science technique used to grow crystalline films on substrates through solid-state diffusion processes. This method involves the deposition of a thin layer of material that undergoes a phase transformation, enabling the alignment of the crystal lattice between the substrate and the deposited layer. SPEG is particularly important in the fabrication of semiconductor devices, as it enhances material quality and electronic properties by minimizing defects and improving crystallinity. The technique is essential for applications in microelectronics and optoelectronics, where precision and quality of the epitaxial layers are critical.
