摘要:
A wireless terminal capable of securing the number of station units capable of simultaneous communication with one unit of access point, reducing power consumption, and ensuring stable communication quality. In the wireless terminal (100), an interference determining section (109) determines whether or not an interference wave is at a predetermined level or more on the basis of the RSSI and SNR of the received signals which are calculated by an RSSI (Received Signal Strength Indicator) calculating section (104) and SNR (Signal to Noise Ratio) calculating section (105) and the presence/absence of a demodulation error notified from a demodulation section (108). A number-of-retransmission upper limit setting section (113) sets the upper limit of the number of retransmission smaller than when the interference wave is at the predetermined level or lower if the interference wave is at the predetermined level or more. A WLAN transmitting circuit (115) repeats the transmission of a transmitting signal by the upper limit number of retransmission till the transmission of the transmitting signal is successful.

A solid-state image pickup device includes, in a substrate, a plurality of photoelectric conversion regions for subjecting incoming light to photoelectric conversion, a reading gate for reading a signal charge from the photoelectric conversion regions, and a transfer register (vertical register) for transferring the signal charge read by the reading gate. Therein, a groove is formed on the surface side of the substrate, and the transfer register and the reading gate are formed at the bottom part of the groove. With such a structure, in the solid-state image pickup device, reduction can be achieved for the smear characteristics, a reading voltage, noise, and others.
摘要:
A first hard mask is formed on a polysilicon film or a target member to be etched, on which a second hard mask composed of amorphous silicon is formed. Ions of boron or the like are implanted into a desired portion of the second hard mask, and then the first hard mask is etched with a mask of the second hard mask. Only the portion not ion-implanted of the second hard mask is etched off by wet etching. A sidewall film is formed on sidewalls of the first hard mask, and then the first hard mask having an upper portion exposed, not covered with the second hard mask is selectively etched off.

According to the present invention, in a CAD apparatus, circuit data for a circuit diagram created through circuit design processing is stored in a circuit database. Based on the circuit data stored in the circuit database, the respective logic types of components are discriminated and set for the component in the circuit data. Moreover, by adding logically transparent nets to the circuit data stored in the circuit database, DRC data dedicated to a DRC is created and stored in a DRC database. A DRC execution unit performs the DRC, by utilizing the DRC data stored in the DRC database.
摘要:
Method of forming a multilayer interconnection structure that includes a contact hole for reliably connecting between layers, without damaging a substrate. A column shaped mask material is formed in a position for forming a contact hole using a resist, and an interlayer insulating film is applied to the whole surface of the substrate excluding the mask material. Then, the mask material is removed by a method such as peeling. As a result, a hole generated thereby is used as a contact hole.
