Latest Patents

Cécile Jenny's latest patents include innovations related to metal shield trenches and metal substrate contacts supported within the premetallization dielectric (PMD) layer of an integrated circuit using a middle end of line (MEOL) process. One of his patents describes a semiconductor substrate that includes a photodiode region and a charge storage region electrically coupled to the photodiode region. This design features a capacitive deep trench isolation (CDTI) structure with a conductive region positioned between the photodiode region and the charge storage region. The patent outlines a contact etch stop layer that overlies the semiconductor substrate, along with a premetallization dielectric layer. The invention includes a first trench filled with a metal material that extends through the premetallization dielectric layer and bottoms out at or in the contact etch stop layer. A second trench, also filled with metal material, extends through both the premetallization dielectric layer and the contact etch stop layer, reaching the conductive region of the CDTI structure. The metal-filled first trench serves as an optical shield between the photodiode region and the charge storage region, while the second trench forms a contact for biasing the CDTI structure.
