Latest Patents

Jean-Michel Missiaen holds a patent for a method of preparing a recrystallized silicon substrate with large crystallites. This method involves several key steps: first, providing a polycrystalline silicon substrate with an average grain size of less than or equal to 10 micrometers. Next, the substrate undergoes overall homogeneous plastic deformation at a temperature of at least 1000°C. Following this, localized plastic deformation is applied in multiple areas of the substrate, with specific spacing between these areas. Finally, the substrate is subjected to recrystallization heat treatment in solid phase at a temperature greater than that used in the previous step, resulting in the desired substrate.
