His work focuses on innovative methods for fabricating semiconductor components, which have implications for various electronic applications.

Latest Patents

One of his latest patents is a method of fabricating semiconductor components. This method includes at least one step of etching an upper layer formed on a substrate. Prior to forming the upper layer, a set of marker layers separated by intermediate layers of predetermined thicknesses is grown. The marker layers and adjacent intermediate layers have different refractive indices. During the etching process, refractive index discontinuities are detected optically, and etching is stopped when the sequence of optically detected discontinuities corresponds to a reference sequence representative of the thicknesses of the intermediate layers.

Another significant patent involves the method of forming a metal contact on a projection on a semiconductor. In this process, a metal contact is formed by etching a metal film that is locally protected by a spot of photosensitive resin. The resin is then caused to flow in the presence of vapor of a solvent, forming a protective spot of increased size. This larger spot allows for the etching of the semiconductor substrate while ensuring that the projection is automatically aligned relative to the metal contact. The resin remains photosensitive, enabling subsequent etching. This invention is particularly applicable to the manufacture of avalanche diodes.
