A system and method may determine the operating parameters, such as voltages, of MOS transistors within a circuit design by testing or simulation, for example and may identify a MOS transistor operating with its drain voltage higher than its gate voltage in the circuit. The design system and method may substitute a smaller transistor, having a high-k dielectric layer, for the original transistor in the circuit design.

A method for fabricating a semiconductor device includes forming a first mask pattern on a first film to extend in a first direction, forming a first spacer on either side wall of the first mask pattern, forming a second film to cover the first spacer and the first film, and forming a second mask pattern on the second film. The second mask pattern extends in a second direction different from the first direction. The method further includes forming a second spacer on either side wall of the second mask pattern, etching the first film using the first spacer and the second spacer as etch masks to form a contact pattern, and removing the first and second spacers to expose the contact pattern.

Disclosed a transmission apparatus in a CDMA mobile communication system. Transmission frames each have a plurality of time slots, and each of the time slots includes two data parts having the same length, a midamble intervening between the data parts, and a guard period for dividing the consecutive time slots. The transmission apparatus modulates the frames into a radio signal with a modulation signal and transmits the modulated radio signal using a plurality of antennas. A power amplifier amplifies the radio signal. A controller generates a switching control signal in a guard period of time slots of a frame associated with the radio signal amplified by the power amplifier. A switch switches the amplified radio signal from the power amplifier between a first and a second antenna in response to the switching control signal.

TSTD apparatus and method for a TDD CDMA mobile communication system

Disclosed is an uplink random access procedure in an NB-TDD (Narrow Band Time Division Duplexing) system. To achieve an acknowledgement for data transmission from a UTRAN (UMTS Terrestrial Radio Access Network), a UE selects one of a plurality of sync codes by which the UTRAN identifies UEs that request data transmission and transmits the selected sync code in a time slot of a sub-frame to the UTRAN. Then, the UE receives the sync code information, information about the arrival time of the sync code, time update information indicating a variation in the transmission time of data, and power information indicating an adjustment to a power gain in the UE from the UTRAN on an FPACH (Fast Physical Access Channel). The UE transmits the data on a P-RACH (Physical Random Access Channel) mapped from the FPACH according to the time update information and the power information.
