CMP slurry stability Chemical-mechanical polishing (CMP), is a technique used in semiconductor fabrication for planarizing a wafer or other substrates. This removes material and tends to even out any irregular topography, making the wafer flat or planar at the Angstrom level. Cerium(IV) oxide, also known as ceria, is an oxide of the rare earth metal
STUDY OF THE RELEASE OF ON ENCAPSULATED ACTIVE IN DOUBLE EMULSION (DONE IN COLLABORATION WITH ADEMTECH) Double emulsions are colloidal systems of great interest for the cosmetics industry as they enable to encapsulate both hydrophilic and lipophilic molecules. However, their formulation is very delicate and requires an important knowhow. Their characterization is also quite limited
