Abstract:
A method for manufacturing an ink jet printer head and the ink jet printer head are provided to suppress reaction layer which is generated on the bottom of nozzle layer. A method for manufacturing an ink jet printer head comprises: a step of forming a heater for heating ink and an electrode for providing current to the heater; a step of applying a first negative photoresist composition on a substrate; a step of patterning by photo lithography and forming a flow path forming layer; a step of applying nonphotosensitive soluble polymer composition to form sacrificial layer; a step of planarizing the upper side of flow forming layer and sacrificial layer; a step of forming ink supply port on the substrate; and a step of removing sacrificial layer.
Abstract:
A developing apparatus for a semiconductor device fabrication is provided to reduce the loss of a wafer and to improve qualities of products by preventing the contamination of the wafer using a cleaning unit. A developing apparatus for a semiconductor device fabrication includes a body(100), a spin chuck, a nozzle unit, a nozzle base and a cleaning unit. The spin chuck(110) is installed on the body in order to load stably a wafer. The nozzle unit(300) is installed at the body. The nozzle unit includes a spraying port(321) capable of spraying a developer. The nozzle base(400) is installed at the body in order to supply a space capable of storing the nozzle unit. The cleaning unit is installed on the nozzle base in order to clean the spraying port.
Abstract:
An apparatus for manufacturing a semiconductor device is provided to form a photoresist film with a uniform thickness on a wafer by supplying a constant amount of photoresist on the wafer. An apparatus for manufacturing a semiconductor device includes a photoresist supply line(60), a valve(50), and a controller(100). The photoresist supply line supplies a photoresist from a photoresist supply portion to a photoresist spray portion. The valve is implemented on a photoresist supply line and controls an amount of the photoresist according to an amount of air. The controller includes an air amount adjuster, an air amount measuring portion, and an air amount display portion. The air amount adjuster controls the amount of air. The air amount measuring portion measures the amount of air, which is controlled by the air amount adjuster. The air amount display portion displays the amount of measured air. The controller supplies air to the valve.
