Title: Innovations of Francois Roy in Photosensitive Matrix Technology

Introduction

Francois Roy is a notable inventor based in Grenoble, France. He has made significant contributions to the field of semiconductor technology, particularly in the development of photosensitive matrices. With a total of 2 patents, his work has advanced the capabilities of imaging technologies.

Latest Patents

Francois Roy's latest patents include a fabrication method for a CCD frame transfer photosensitive matrix. This innovative matrix features a P type semiconductor substrate and an N type channel layer, which is separated by narrow insulating zones into multiple columns. The design incorporates a network of transfer grids that divide the columns into numerous 'pixels'. A key aspect of this invention is the weakly doped P type base layer, which houses buried anti-blooming diodes. These diodes consist of a narrow, strongly doped N type drain that runs parallel to the insulating zones, enhancing the optical aperture and improving the spectral response towards the red side of the spectrum.

Another significant patent by Roy is the CCD frame transfer photosensitive matrix with vertical anti-blooming. Similar to his previous invention, this matrix also includes a P type semiconductor substrate and an N type channel layer. The arrangement of the anti-blooming diodes and the protective screen beneath the drain contributes to an optical aperture close to unity, further enhancing the matrix's performance.
