20100136764 | METHOD OF MANUFACTURING AN INTEGRATED CIRCUIT - A method of manufacturing an integrated circuit comprises depositing a electrically resistive layer of a material for serving as a thin film resistor (TFR), depositing an electrically insulating layer on the resistor layer, removing the electrically insulating layer from outside an electrically active area of the resistor layer corresponding to a target TFR area, and depositing an electrically conductive layer of an electrically conductive material such that the conductive layer overlaps the target TFR area and the conductive layer electrically contacts the resistor layer outside the target TFR area. | 06-03-2010 |
20110204482 | Method and Electronic Device for a Simplified Integration of High Precision Thinfilm Resistors - The invention relates to a method of manufacturing an integrated circuit. An electrically resistive layer of a material for serving as a thin film resistor (TFR) is deposited. A first electrically insulating layer is deposited on the electrically resistive layer of the TFR. An electrically conductive layer of an electrically conductive material is deposited. An area is left without the conductive layer and the area overlaps the electrically resistive layer of the TFR. A second electrically insulating layer is deposited on top of the conductive layer. A first VIA opening is etched through the second insulating layer, the area without the conductive layer adjacent to the electrically conductive layer and through the first insulating layer down to the electrically resistive layer of the TFR. A conductive material is deposited in the first VIA opening so as to electrically connect the conductive layer and the electrically resistive layer of the TFR. | 08-25-2011 |

20140103489 | Electronic Device Comprising a Semiconductor Structure Having an Integrated Circuit Back End Capacitor and Thin Film Resistor and Method of Manufacturing the Same - An electronic device comprising a semiconductor structure having an integrated circuit back end capacitor and an integrated circuit back end thin film resistor and a method of manufacturing the same is provided. The semiconductor structure comprises a first dielectric layer, a bottom plate of the capacitor and a thin film resistor body. Furthermore, there is a second dielectric layer which is disposed on the bottom plate of the capacitor and on top of the thin film resistor body. A top plate of the capacitor is disposed on the second dielectric layer in a region of the second dielectric layer which is defined by the lateral dimensions of the bottom plate of the capacitor. The bottom plate and the resistor body are laterally spaced apart layers which are both disposed on the first dielectric layer and which are composed of a same thin film material. | 04-17-2014 |
20140239449 | THREE PRECISION RESISTORS OF DIFFERENT SHEET RESISTANCE AT SAME LEVEL - An integrated circuit contains three thin film resistors over a dielectric layer. The first resistor body includes only a bottom thin film layer and the first resistor heads include the bottom thin film layer, a middle thin film layer and a top thin film layer. The second resistor body and heads include all three thin film layers. The third resistor body does not include the middle thin film layer. The three resistors are formed using two etch masks. | 08-28-2014 |
