Our test lab received a SiS655TX-based mainboard, Gigabyte 8S655TX Ultra — for 800 MHz Pentium 4 CPU. As for the specifications, they are rather standard, as there is almost no difference between SiS655TX and SiS655FX: dual-channel DDR400/333, 5 x PCI slots, AGP 8x, Gigabit Ethernet controller, 6-channel audio, Serial ATA, ATA133 RAID support, etc.
Intel, its specialists made a significant breakthrough in the field of newer chip materials. The company claims it will allow to considerably reduce leakage currents alongside chip energy consumption and heat emission.
Already in 2007 Intel is going to use special high-k dielectrics in transistor gates that, according to specialists, will allow to reduce leakage currents by at least a factor of 100! According to Moore´s Law, the amount of transistors might reach a billion by that time. In 2007 the company plans to move to 45nm process technology. At that time the usual silicon dioxide will be replaced by a still undisclosed high-k dielectric. Alongside the company is going to stop using polycrystalline silicon additions during forming transistor gate electrodes and start using two different metals for NMOS and PMOS transistors.
Essentially the leakage problem is: the thickness of silicon dioxide layer used as dielectric is currently 5 atoms that results in electrons tunnelling through the oxide level in the enabled state and increases energy consumption. The transition to high-k materials makes the transistor current in the enabled state just slightly higher than in the disabled state. This naturally reduces leakages.
The leakage reduction effect of high-k oxides has been known for a long time, however scientists have been searching for suitable materials. The already known high-k materials like hafnium, zirconium, etc. oxides usually result in considerable channel current reduction under gate dielectrics and lead to serious problems of setting gate operate threshold voltage, especially in PMOS transistors.
More details on new high-k dielectric technologies are to be presented by Robert Chau, lead developer of Intel´s lab in Hillsboro, Oregon, on Thursday at International Gate Insulator Workshop in Tokyo. The presentation will describe the development of NMOS and PMOS transistors with 80nm gates and the usage of 1.4nm (14 Angstrom) dielectrics.

DFI launched its latest revisions of the unique LANParty motherboard series – LANParty NFII Ultra B and LANParty
PRO875B. The new LANParty NFII Ultra B for AMD platform combines popular features of the previous version with many performance integrations that make it a LAN gamer´s dream motherboard. The new LANParty PRO875B for Intel platform
supports the latest Intel Pentium 4 3.20 GHz Extreme Edition processors and CMOS Reloaded technology to deliver one unmatchable gaming platform.
Below is an excerpt from the official press release: "Similar to the previous design, the LANParty NFII Ultra B takes full advantage of the nForce2 Ultra 400/MCP-T chipset architecture, and is optimized for dual channel DDR400 memory and 8X AGP. Designed with the most discerning gamers in mind, Revision B LANParty features the new dual Gigabit LAN and 10/100 Ethernet for desired network reliability, extra space around the AGP slot to accommodate today´s new card design, additional Southbridge heat sink to maximize cooling, mounting holes around the CPU socket for water cooling, and the latest Silicon Image 4-channel Serial ATA. LANParty NFII Ultra B is the first in the series to offer support for 4-channel Serial ATA and Serial ATA RAID (0,1,0+1) to enable a compact system design with faster transfer rate. Other integrated features include 8 USB 2.0 ports, 4 IEEE 1394 Firewire ports, and 6-channel audio with SPDIF in/out to complete the offering.
For the overclockers and the power users, LANParty NFII Ultra B features CMOS Reloaded technology with 2 sets of CMOS under each BIOS setting. With CMOS Reloaded, for the first time the users can now save the overclocked settings without having to record manually, customize by naming each CMOS configuration, and load the various CMOS configurations using hot keys on the keyboard. This DFI patented technology automates overclocking and allows each CMOS configuration to be saved with a different operating system, thus making today´s PCs truly versatile. Further to make it the ultimate nForce2 enthusiasts´ motherboard, improvements were made to its overclockability. First in the market, LANParty NFII Ultra B features DRAM voltage from 2.6V to 3.3V (0.1V step), complete CPU ratio control from 5X to 22X and chipset voltage from 1.6V to 1.9V. Additional DRAM timing control was also implemented to enable refresh cycle time control, row cycle time control, RAS-to-CAS write delay time control, SuperBypass control, and DIMM driving strength and signal slew rate control.
For the Intel lovers, the LANParty PRO875B provides high-end features the power users have become accustomed to. Based on the Intel i875P/ICH5R chipset, this motherboard supports the latest dual channel DDR400 memory up to 4 MB, 8X AGP, and Performance Acceleration Technology (PAT) for advance computing. Broadband connection is enabled by the Intel CSA (Communications Streaming Architecture) Gigabit LAN with direct access to system memory to offer up to double the data transfer rate. In addition to the DFI proprietary RAID 1.5, this revision B motherboard also offers Serial ATA RAID for slim system design. A new feature added to this release is the CMOS Reloaded technology to facilitate the most flexible overclocking on the Intel platform. Similar to the AMD based NFII Ultra B, LANParty PRO875B will offer 2 sets of CMOS settings and future expansion capability through BIOS updates. When coupled with the latest Intel Pentium 4 processor Extreme Edition, this ultimate combination enhances visual realism for gamers and adds additional processing power with its larger cache and HyperThreading technology."

Nippon Leiz Co, Ltd exhibited at the FPD International 2003 its new back-to-back light emitting diode (LED) backlight for mobile phones that have a main LCD and a sub-LCD.
Thus far, many mobile phones have been employing two LED backlights, but with the new technology only one backlight is necessary. The backlight supports the 2-in. main LCD and the 1.2-in. sub-LCD.
Previously, if one backlight unit was used for both the main and sub-LCDs, the sub-screen became visible from the main screen. Nippon Leiz´s new optical design was optimized to solve this problem.
There are two kinds of new backlights: regular and brighter. Regarding the average brightness of a regular unit, the brightness of the main LCD is 1,500 nit, and that of the sub-LCD is 1,600 nit. The average brightness for the main LCD of the brighter unit is 1,900 nit, and that of the sub-LCD is 2,050 nit. The electric power consumption of both types is 210mW.
The regular one was commercialized on October 29, and the brighter type was showcased for reference, slated for commercialization in the spring of 2004.
