METHOD OF SCREEN PRINTING IN MANUFACTURING AN IMAGE SENSOR DEVICE

A method of manufacturing an image sensor device includes providing a metalized thin film transistor layer on a glass substrate; forming an inter-layer dielectric layer on the metalized thin film transistor layer; forming a via through the inter-layer dielectric layer; forming a metal layer on the inter-layer dielectric for contacting the metalized thin film transistor layer; forming a bank layer on the metal layer and the inter-layer dielectric layer; forming a via through the bank layer; forming an electron transport layer on the bank layer and within the bank layer via for contacting an upper surface of the metal layer; forming a bulk hetero-junction layer on the electron transport layer; forming a hole transport layer on the bulk hetero-junction layer; and forming a top contact layer on the hole transport layer. The bulk hetero-junction layer and/or the top contact layer are applied using a screen printing technique.
