Abstract:
PURPOSE: An electrostatic spraying printing device is provided to spray liquid drops in a circle shape to form an ellipse shape with the major axis which is extended unidirectionally or a linear shape by comprising a guide electrode unit, thereby forming organic patterns which are uniform in length. CONSTITUTION: An electrostatic spraying printing device (100) comprises a nozzle (110), a first voltage feed unit (120), two guide electrodes (131,133), and a conductive mask (140). The nozzle sprays a solution which includes an organic substance. The first voltage feed unit divides the solution which is sprayed from the nozzle by applying positive voltage to the nozzle. The guide electrodes are arranged with a space from each other across the end part of the nozzle, extended toward a first direction, and grounded. The conductive mask is equipped with a linear opening unit which is extended to intersect with the two electrodes, and applied with positive voltage.

PURPOSE: A method for preparing an organic multilayer thin film using an electrospray method is provided to improve efficiency regardless of size by improving the flow of holes and electrodes. CONSTITUTION: A first electrospray solution and a second electrospray solution are manufactured. A first electrical spray solution is injected onto a hole transport layer. A light emitting layer is formed. The second electrospray solution is injected onto the light emitting layer. An electron transfer layer is formed. A multi-layered thin film including the light emitting layer and the electron transport layer is dried.

Abstract:
PURPOSE: An apparatus and a method for measuring the thickness of an in-situ thin film using impedance and a recording medium thereof are provided to skip a special deposition thickness check process since the thin film deposition thickness is measured in real time under an in-situ situation. CONSTITUTION: A substrate(30) is installed in a chamber(10). Plasma gas(20) includes a sheath layer. A source RF power(40) applies source power to the chamber. A bias RF power(50) applies bias power to the substrate. An impedance measurement unit(60) measures a measurement impedance in real time. A display unit(90) displays the thickness of a thin film(70) measured in a thickness calculation unit(80) for a user.
