  • Publication number: 20250204132
    Abstract: The invention relates to a method for manufacturing an optoelectronic device (1) with a diode array (20), including the following steps: producing an electret layer (30) having conversion zones (Zc) separated two-by-two by a spacing zone (Ze) with zero surface potential, where each conversion zone (Zc) is formed of a plurality of so-called polarized elementary zones (32) with non-zero surface potential, spaced apart two-by-two by a so-called non-polarized elementary zone (33) with zero surface potential, such that the conversion zone (Zc) has a structured surface potential; producing color conversion pads (P), by placing the electret layer (30) in contact with a colloidal solution(S) containing photoluminescent particles (p).

  • Patent number: 12278315
    Abstract: A method for manufacturing an optoelectronic device including an array of diodes and photoluminescent pads arranged opposite at least one diode, including making an electret layer over the array of diodes, by localized polarization or depolarization, optically, so as to form surface potential patterns; and making the photoluminescent pads, by contact of the electret layer with a colloidal solution containing photoluminescent particles, which are then deposited over the upper face of the electret layer opposite the predefined surface potential patterns, thereby forming the photoluminescent pads.

  • Publication number: 20250081685
    Abstract: The invention relates to a method for manufacturing an optoelectronic device (1) including an array of diodes (D1, D2, D3) and an array of colour conversion portions (P1, P2), including the following steps: providing the array of diodes (D1, D2, D3), and the upper electrode layers (E1, E2, E3); depositing a dielectric layer (26) having a substantially zero surface potential; applying a potential difference between an electrode (2) and the first upper electrode layers (E1), resulting in the formation of first patterns (M1) with non-zero surface potential in the dielectric layer (26); producing the first colour conversion portions (P1), by contacting the dielectric layer (26) with a colloidal solution (S1) containing first photoluminescent particles (p1).

  • Patent number: 11955585
    Abstract: A method for coating chips resting, by a rear face opposite to a front face, on a main face of a support substrate, and separated from each other by an inter-chip space, includes a step of forming a photosensitive coating film covering the front faces and the inter-chip spaces. The method further includes a first photolithographic sequence which comprises an insolation sub-step, and a dissolution sub-step. The sequence leads to a partial removal of the photosensitive coating film so as to maintain the film exclusively at the inter-chip spaces and, advantageously recessed relative to the front faces.

  • Patent number: 11592601
    Abstract: The invention relates to a diffuser 3 intended to be facing a light source 1 comprising a transmission layer 10 and a diffusion layer 22, 23 intended to diffuse a light transmitted by the light source, the diffuser being characterised in that the diffusion layer comprises a plurality of metal structures 200, 200a, 200b, called metal nanostructures, having dimensions less than a wavelength of the light transmitted, said metal nanostructures having varied sizes and being distributed within the diffusion layer such that adjacent metal nanostructures have between them, varied distances and preferably less than the wavelength of the light transmitted. The invention also relates to a method for manufacturing such a diffuser, and a display system comprising such a diffuser.

  • Patent number: 9673269
    Abstract: An integrated capacitor comprises a layer of dielectric material known as functional dielectric material based on crystallized material of perovskite type, between at least one first electrode known as a bottom electrode at the surface of a substrate and at least one second electrode known as a top electrode, said electrodes being electrically insulated by a layer of electrically insulating material in order to allow at least one contact on the top electrode. The electrically insulating material is made of an amorphous dielectric material of perovskite type having a dielectric constant lower than that of the crystallized material of perovskite type. The contact is formed from an etched contacting layer in contact with the electrically insulating dielectric layer level with its surface parallel to the plane of the layers. A process for manufacturing such an integrated capacitor is also provided.
