摘要:
In a method of forming a hole, an insulation layer is formed on a substrate, and a preliminary hole exposing the substrate is formed through the insulation layer. A photosensitive layer pattern including an organic polymer is then formed on the substrate to fill the preliminary hole. An etching gas including hydrogen fluoride (HF) or fluorine (F2) is then provided onto the photosensitive layer pattern to etch the insulation layer so that width of the preliminary hole is increased.

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.

A block management method for OPC model calibration includes calculating differences in several different optical functions between first patterns of a first mask and patterns of a second mask corresponding to the first patterns but differing therefrom by a predetermined bias, selecting one or more of the optical functions based on the calculated differences, clustering data of variations in the values of the calculated differences in the selected ones of the optical functions, selecting respective ones of the first patterns in consideration of how the data clusters, and designating the selected first patterns as test patterns.

In a memory device having a carbon nanotube and a method of manufacturing the same, the memory device includes a lower electrode, an upper electrode having a first void exposing a sidewall of a diode therein, an insulating interlayer pattern having a second void exposing a portion of the lower electrode between the lower electrode and the upper electrode, and a carbon nanotube wiring capable of being electrically connected with the diode of the upper electrode by a voltage applied to the lower electrode. The memory device may reduce generation of a leakage current in a cross-bar memory.
