Abstract

A method for manufacturing a device with micro-shutters, e.g., a light modulating device, includes the following steps: producing a first grid presenting cells; providing a plane support by depositing a layer of organic material on the grid filling the cells; producing a second grid on the layer of organic material; depositing a fine metallic layer on the second grid; cutting shutters and shutter attachments in the fine metallic layer; and removing the organic material layer in the cells to free the shutters.
