Title: System and method for estimating interfrequency measurements used for radio network function
Inventor: JETZEK ULRICH
IPC: H04J13/00
Filed: 1999-12-22
Granted: 2003-03-01
Abstract: Systems and methods for estimating inter-frequency measurements used for radio network functions are disclosed. The systems and methods described allow systems to evaluate the quality of a second frequency by using offset adjusted measurements on a first frequency. By using the described methods, system capacity is increased by providing a ""low cost"" measurement mechanism for support of handover that substantially balance the load between two or more frequency bands. By using the propsed method, handover can be performed more frequently and the interference within each frequency band can therefore be kept at a more optimal level.

Title: Dual-damascene interconnect structures and methods for fabricating same
Inventor: ZHAO BIN
IPC: H01L21/768
Filed: 2000-01-10
Granted: 2001-06-16
Abstract: An interconnect fabrication process and structure provides barrier enhancement at the via sidewalls and improved capability to fabricate high aspect ratio dual damascene interconnects. A via structure is patterned into the via dielectric first, then a dielectric barrier (for example, anisotropically etched silicon nitride) is formed only along the via sidewalls in the dual damascene structure prior to deposition of a metal barrier (for example, Ta/TaN). In this way, the effective barrier thickness along the bottom of the via is increased, eliminating the structure's susceptibility to metal migration. The absence of dielectric barrier along the interconnect trench sidewalls leads to low interconnect resistance and low interconnect capacitance. The present invention also provides an improved fabrication method for obtaining high aspect ratio dual damascene interconnect structures.

IPC: H04N5/775
Filed: 2000-01-31
Granted: 2001-10-11
Abstract: A radio frequency (RF) modulator for use with an antenna, a television receiver, and a video tape recorder or the like. The RF modulator contains a modulator which converts an input video signal and an input audio signal into a modulated signal having a predetermined channel frequency; an amplifier amplifying an input signal from an antenna input terminal; and a mixer which mixes the modulated signal with the input signal amplified by the amplifier to output a mixed signal from an antenna output terminal. A first switch is connected in parallel with the amplifier between the antenna input terminal and the antenna output terminal; a second switch is connected between the antenna input terminal and the amplifier; and a third switch is connected between the mixer and the antenna output terminal. When the amplifier and the modulator are not used, a signal path from the antenna input terminal to the antenna output terminal through the first switch can be formed and isolated from the amplifier and the modulator by turning the second and third switches off, so as to reduce power consumption and signal loss.

Granted: 2002-06-21
Abstract: A first telecommunications system (201) has at least partially geographically overlapping coverage with a second telecommunications system (202), with radio transmission access in the first telecommunications system utilizing code division multiple access (CDMA) with a time division multiple access (TDMA) component. A base station (BS) of the first telecommunications system communicates over an air interface with a subscriber station (SS) and broadcasts a common broadcast physical channel (BPCH) on at least an active carrier/timeslot combination (C/TS). The common broadcast physical channel includes broadcast system identity information. The subscriber station uses the broadcast system identity information to distinguish between transmissions of the first telecommunications system and the second telecommunications system. Moreover, the subscriber station uses the broadcast system identity information for framing transmissions in the first telecommunications system. The base station of the first system broadcasts at least two common broadcast physical channels active on different timeslots. Preferably, a fixed direct sequence CDMA code is employed for the common broadcast physical channel. In accordance with an instant dynamic channel selection procedure of the present invention, the subscriber station selects a carrier/timeslot for sending an access request to the first system base station. The carrier/timeslot selected by the first system subscriber station for sending an access request to the first system base station is also used for a traffic channel. Preferably, the first system subscriber station selects a least interfered carrier/timeslot as the carrier/timeslot for sending an access request to the first system base station. In response to the access request, the first system base station sends an answer on a next down-link carrier/timeslot included in a duplex pair with the carrier/time slot which the first system subscriber station selected for sending the access request to the first system base station. At an given moment a connection between the first system base station and the subscriber station is borne on a physical channel of the first telecommunications system, the physical channel being defined by a code, timeslot, and frequency.

Abstract: A thin film processing method for processing a thin film by irradiating the thin film with light is disclosed. The irradiation unit of the light beam is the irradiation of the thin film with the first and the second light pulses.

Preferably one irradiation unit of the light beam comprises the irradiation with the first light pulse and the irradiation with the second light pulse started substantially simultaneously with the start of the irradiation with the first light pulse. The following two inequalities are satisfied: (the pulse duration of the first light pulse) < (pulse duration of the second light pulse), and (the irradiation intensity of the first light pulse) ≥ (the irradiation intensity of the second light pulse). A silicon thin film having a small trap level density can also be formed by light irradiation.
