摘要： A method of forming a carbon nanotube fuse by depositing a carbon nanotube layer, then depositing a cap layer directly over the carbon nanotube layer. The cap layer is formed of a material that has an insufficient amount of oxygen to significantly oxidize the carbon nanotube layer under operating conditions, and is otherwise sufficiently robust to protect the carbon nanotube layer from oxygen and plasmas. A photoresist layer is formed over the cap layer, and the photoresist layer is patterned to define a desired size of fuse. Both the cap layer and the carbon nanotube layer are completely etched, without removing the photoresist layer, to define the fuse having two ends in the carbon nanotube layer. Just the cap layer is etched, without removing the photoresist layer, so as to reduce the cap layer by a desired amount at the edges of the cap layer under the photoresist layer, without damaging the carbon nanotube layer. The photoresist layer is removed, and electrically conductive contacts are formed on each of the two ends of the fuse.

摘要： An electrostatic discharge (ESD) protection circuit for protecting a protected circuit is coupled to an input pad. The ESD circuit includes a nanotube switch electrically having a control. The switch is coupled to the protected circuit and to a discharge path. The nanotube switch is controllable, in response to electrical stimulation of the control, between a de-activated state and an activated state. The activated state creates a current path so that a signal on the input pad flows to the discharge path to cause the signal at the input pad to remain within a predefined operable range for the protected circuit. The nanotube switch, the input pad, and the protected circuit may be on a semiconductor chip. The nanotube switch may be on a chip carrier. The deactivated and activated states may be volatile or non-volatile depending on the embodiment.

A second support layer is formed with an opening that defines a top chamber above the lower chamber, the top chamber including an extension region that extends beyond an edge of the lower chamber to expose a portion of the top surface of the first support layer. A roof layer covers the top of the top chamber and includes an aperture that exposes a portion of the extension region of the top chamber and includes a plug that extends into the aperture in the roof layer to seal the top and bottom chambers. The memory cell further includes an electrode that overlies the crossbar element such that electrical signals can activate the electrode to attract or repel the crossbar element to set a memory state for the transistor.
