Semiconductor device

InactiveUS20090273961A1Increase currentReduce locationDigital storageLayered structureBit plane
A technique for increasing rewriting current without increasing a power supply voltage and also reducing location dependency inside a memory array of a resistive state after the rewriting is provided in a resistance change memory in which the resistance value of a memory cell changes between logical values “1” and “0”. In the resistance change memory, bit lines are formed into a layered structure, the bit line select switches for connecting to the global bit line are provided at both ends of the local bit line, and a control method of the bit line select switches is changed in the writing and the reading, thereby realizing the optimum array configurations for each of them. More specifically, in the writing and the reading, two current paths are provided in parallel by turning ON the bit line select switches simultaneously.

Impedance conversion circuit, drive circuit, and control method of impedance conversion circuit

An impedance conversion circuit IPC1 including: an operational amplifier OP1 connected as a voltage follower and supplied with, as an input voltage Vin, a voltage selected from 2j levels of voltages (j is a positive integer) based on data of high j bits of the gray scale data; and an output voltage setting circuit OVS1 for precharging or discharging an output of the operational amplifier OP1 based on data of a most significant bit of low k bits (k is an integer more than 1) of the gray scale data. The operational amplifier OP1 outputs, as an output voltage, a voltage having a difference from the input voltage by a dead zone width after the output voltage setting circuit OVS1 precharges or discharges the output of the operational amplifier OP1. The dead zone width is determined by an operating current of the operational amplifier OP1. The operating current is varied based on data of low k bits of the gray scale data.

Liquid crystal panel for liquid crystal display device

To utilize effectively the panel space of the liquid crystal panel, this invention has provided a wiring structure, in which the seal material and BM are coated in a superposition and the UV light is irradiated from one side of the TFT substrate; this invention has also provided a wiring structure, in which the seal material can still be irradiated by the UV light with high efficiency, meanwhile, the drop of the resistance value of the metal wiring on the TFT substrate can be restricted to a specific range. The solution is: the liquid crystal dropped is sandwiched between the TFT substrate and the CF substrate, meanwhile the liquid crystal panel is formed by adhering the light cured seal material disposed at the peripheral area of two substrates. In the adhering-formed liquid crystal panel, for the wiring portion, which is the portion of wiring disposed on the TFT substrate superposing the light cured seal material, the wiring structure is formed as follows, that is, the region of the seal material is divided into three regions, an adjacent region, a middle region and an outer region. The function of the respective regions must be held, and the resistance of the metal wiring is minimized under the precondition that the respective function is satisfied sufficiently.

Semiconductor physical quantity sensor of electrostatic capacitance type and method for manufacturing the same

In a semiconductor physical quantity sensor of electrostatic capacitance type, mutually facing peripheral areas (bonding areas) of a glass substrate and a silicon substrate are contacted for anodic bonding, while at the same time, both substrates have an anodic bonding voltage applied therebetween so as to be integrated. A fixed electrode is formed on a bonding face-side surface of the silicon substrate, while a movable electrode is formed on a bonding face-side surface of the semiconductor substrate. An equipotential wiring, which short-circuits the fixed electrode to the movable electrode as a countermeasure to discharge in anodic bonding, is formed on the bonding face-side surface of the glass substrate inside the bonding area before the anodic bonding. After the anodic bonding, the equipotential wiring is cut and removed. By manufacturing the sensor in this manner, the fixed electrode of the insulating substrate is made equipotential to the movable electrode of the semiconductor substrate when the insulating substrate is anodically bonded to the semiconductor substrate, thereby preventing discharge from occurring. Accordingly, it is possible to obtain a high bonding strength and desired sensor characteristics without causing bonding voids to occur and a sensor chip to increase in size.
