Abstract:
An organic thin film transistor manufacturing method and the thin film transistor manufactured by the same method are provided, which improve the interface property of the organic thin film transistor. The gate electrode(2) and gate isolation layer(3) are equipped at the upper part of the substrate(1). The surface processing layer is formed into the PECVD(Plasma-enhanced chemical vapor deposition) method by using the precursor material on the gate isolation layer. The organic semiconductor layer(5) is formed on the surface processing layer(4). The source(6)/drain(7) electrode is formed on the organic semiconductor layer. The precursor within the foam generator is evaporated. The evaporated precursor is flowed in the reactor for the plasma vapor deposition. By using the plasma of the reactor, the thin film polymerized by plasma on the substrate within the reactor is deposited.
Abstract:
The present invention relates to a bonding method for self-aligning using a concave-convex bump structure. The concave-convex bump structure includes a convex bump consisting of a protrusion part and a support part, a concave bump consisting of a groove corresponding to the protrusion part of the convex bump, and a solder deposited on the protrusion part of the convex bump. According to the present invention, a bonding method for inserting the convex bump into the concave bump is to reduce the bad arrangement in a semiconductor bonding process and to improve the mechanical strength by increasing the bonding area of the solder and a separated space after the convex bump is separated and bonded to the concave bump.

본 발명은 반도체 3차원 적층공정에서의 이중 확산방지층을 포함하는 범프 및 그 제조방법에 관한 것으로서, 도전층; 상기 도전층 상에 형성되며, 니켈과 인의 합금을 포함하는 제1확산방지층; 상기 제1확산방지층 상에 형성되며, 구리를 포함하는 제2확산방지층; 및 상기 제2확산방지층 상에 형성되는 솔더층;을 포함하여 이루어지는 것을 특징으로 한다. 본 발명에 의하면, 니켈-인 합금의 확산방지막에 얇은 구리를 적층하여 이중층을 형성함으로써, 3차원 적층공정에서 중요한 두께 증가를 최소화하면서도, 높은 온도의 접합공정 중에, 니켈-인 합금 확산방지막의 결정화로 인한 확산방지효과의 저하를 극복하여, 확산방지막의 붕괴를 지연시킬 수 있으며, 구체적으로 본 발명의 이중 확산방지층의 구성물질인 구리와 솔더층이 반응하여 생기는 금속간화합물을 통해, 니켈의 확산을 막아주는 역할을 함으로써, 확산방지효과가 증가하여, 3차원 적층공정을 통해 완성된 제품의 신뢰성을 현저히 향상시킬 수 있는 장점이 있다.
