Abstract:
PROBLEM TO BE SOLVED: To provide a new structure and a new method for monitoring an operation of an acting integrated circuit in operation. SOLUTION: This invention relates to a method and a structure of an integrated circuit provided with a first transistor and an embeded carbon nanotube field effect transistor (CNT FET) which is adjacent to and smaller than the first transistor. The CNT FET is used for sensing a signal containing any of a temperature signal, a voltage signal, a current signal, an electric field signal and a magnetic field signal from the first transistor. Furthermore, the CNT FET is used for measuring a stress and a distortion in the integrated circuit containing any of a mechanical stress and a mechanical distortion as well as a thermal stress and a thermal distortion. Furthermore, the CNT FET is used for detecting a defective circuit in the integrated circuit. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a gain cell for a memory circuit, a memory circuit comprising multiple gain cells, and a method of producing such gain cells and memory circuits. SOLUTION: A memory gain cell 64 includes a storage capacitor 38, a write device which is electrically coupled to the storage capacitor for charging and discharging the storage capacitor, and a read device. The read device includes one or more semiconducting carbon nanotubes 50 each of which is electrically coupled between a source and a drain. A portion of each semiconducting carbon nanotube is gated by a read gate 60 and the storage capacitor, thereby regulating a current flowing through each semiconducting carbon nanotube from the source to the drain. The current is proportional to the electrical charge stored by the storage capacitor. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
An integrated distribution wiring system for a semiconductor substrate having a number of devices. The distribution system includes additional stripes which are arranged parallel to existing rails carrying power or signals to the devices. These stripes being separable from the rails may be used to make engineering changes such as repairs or modifications of the circuits in the devices or characterizing or diagnosing the devices.
