Latest Patents

One of Le Roux's latest patents is a method for the production of wafers of nitride of element 13, which features a non-zero truncation angle. This invention relates to a method for producing wafers from a self-supported crystal of nitride, extending longitudinally along a main axis orthogonal to the growth face of the crystal. The method includes a phase of cutting the self-supported crystal along transverse cutting planes to obtain wafers, each with a front face that has a non-zero truncation angle near the center.

Another significant patent is for a chemical mechanical planarization slurry and the method for forming it. This CMP slurry includes a carrier and a particulate material, which can be an oxide, carbide, nitride, boride, diamond, or any combination thereof. The slurry also contains an oxidizer selected from various materials, ensuring a material removal rate index (MRR) of at least 500 nm/hr and an average roughness index (Ra) of not greater than 5 Angstroms according to standardized polishing tests.
