Abstract:
1. A method for manufacturing an active plate of a flat display screen comprising a matrix of cells, in which each cell of said matrix of cells comprises an electrode plate connected by a transistor to a first conductive line, said method comprising the steps of: providing, for each cell, an outgrowth coated with an insulator of said first conductive line; etching or making porous an end portion of said outgrowth; laterally growing a P-type-doped/intrinsic/P-type-doped (PIP) or N-type-doped/intrinsic/N-type-doped (NIN) semiconductor structure in the end portion which has been etched or made porous; and establishing a contact at a free end of the PIP or NIN semiconductor structure and forming a gate on a median portion of the PIP or NIN semiconductor structure.
