摘要:
In a method of forming a wiring having a carbon nanotube, a lower wiring is formed on a substrate, and a catalyst layer is formed on the lower wiring. An insulating interlayer is formed on the substrate to cover the catalyst layer, and an opening is formed through the insulating interlayer to expose an upper face of the catalyst layer. A carbon nanotube wiring is formed in the opening, and an upper wiring is formed on the carbon nanotube wiring and the insulating interlayer to be electrically connected to the carbon nanotube wiring. A thermal stress is generated between the carbon nanotube wiring and the upper wiring to produce a dielectric breakdown of a native oxide layer formed on a surface of the carbon nanotube wiring. A wiring having a reduced electrical resistance between the carbon nanotube wiring and the upper wiring may be obtained.

In a method of forming a carbon nano-tube, an oxidized metal layer is formed on a substrate. An insulation layer having an opening is formed on the oxidized metal layer to expose a surface of the oxidized metal layer through the opening. The oxidized metal layer exposed through the opening is converted into a catalyst metal layer pattern for allowing a carbon nano-tube to grow from the catalyst metal layer pattern. The carbon nano-tube grows from the catalyst metal layer pattern to form a carbon nano-tube wire in the opening. Thus, the carbon nano-tube may not grow between the insulation layer pattern and the catalyst metal layer pattern.

Provided are methods of forming a phase change memory device. A semiconductor device having a lower electrode and an interlayer insulating layer may be prepared. The lower electrode may be surrounded by the interlayer insulating layer. Source gases, a reaction gas and a purge gas may be injected into a process chamber of a semiconductor fabrication device to form a phase change material layer on a semiconductor substrate. The source gases may be simultaneously injected into the process chamber. The phase change material layer may be in contact with the lower electrode through the interlayer insulating layer. The phase change material layer may be etched to form a phase change memory cell in the interlayer insulating layer. An upper electrode may be formed on the phase change memory cell.

A semiconductor memory device includes a sub memory cell array region having memory cells each connected between word lines extending in a first direction and bit lines extending in a second direction that is orthogonal to the first direction of extension of the word lines and a sub word line driver region disposed at a side of the sub memory cell array region in the first direction and including sub word line drivers that activate the word lines. A sensing region is disposed at a side of the sub memory cell array region in the second direction and including an equalizer that precharges the bit line in response to a signal transferred through a drive signal line and at least one first control signal driver that activates an inverted control signal line in response to a signal transferred through a control signal line. A conjunction region disposed at an intersection between the sub word line driver region and the sensing region, in which the inverted control signal line is connected to the drive signal line.

A semiconductor device includes a semiconductor package, a circuit board and an interval maintaining member. The semiconductor package has a body and a lead protruded from the body. The circuit board has a first land electrically connected to the lead. The interval maintaining member is interposed between the circuit board and the body. The interval maintaining member maintains an interval between the lead and the first land. Thus, an interval between the lead and the land is uniformly maintained, so that a thermal and/or mechanical reliability of the semiconductor device is improved.
