Abstract: A MEMS (Micro Electro Mechanical System) device and a method of manufacturing the same, in which an detection indicator is formed on a chamber layer stacked on a substrate such that a user easily inspects whether the chamber layer has a required thickness. The MEMS device can include two detection indicators that are formed on the chamber layer and have different depth from each other, or an detection indicator which is formed on the chamber layer and has a tapered sectional shape in which an upper surface of the detection indicator is gradually narrowed in a downward direction such that a user can easily inspect whether the chamber layer has a required thickness. The user can precisely determine whether the chamber layer is planarized to a required thickness by planarizing the detection indicator formed on the chamber layer, and inspecting the detection indicator by using an optical microscope, thereby facilitating inspection for a thickness of the chamber layer.

Abstract: A method of manufacturing a monolithic inkjet printhead wherein the uniformity of the ink flow path is maintained by ensuring that the flow path forming layer and the nozzle layer are completely adhered to each other. The method includes forming a heater and electrode on a substrate, coating a negative photoresist on the substrate, and patterning the photoresist using a photolithography process to form an flow path forming layer that defines an ink flow path. The method further comprises steps for then forming a sacrificial layer so as to cover the flow path forming layer and then flattening upper surfaces of the flow path forming layer and the sacrificial layer using a chemical mechanical polishing (CMP) process such that when a nozzle layer is then formed, the flow path forming layer and the nozzle layer are completely adhered to each other.
