Techniques for forming metal silicide contact pads on semiconductor devices are disclosed, and in one exemplary embodiment, a method may comprise depositing a metal layer on and between a plurality of raised silicon-based features formed on a semiconductor substrate, the metal layer comprising metal capable of reacting with external silicon-based portions of the features to form a metal silicide. In addition, such a method may also include depositing a cap layer on the metal layer deposited on and between the plurality of raised silicon-based features, wherein a thickness of the cap layer on the metal layer between the raised features is greater than or equal to a thickness of the cap layer on the metal layer on the raised features. Furthermore, such a method may also include annealing the structure to cause portions of the metal layer to react with portions of the external silicon-based portions of the features to form metal silicide pads on and between the raised features.

The invention relates to a multifunctional spa device. It is mainly that an inlet of a pump controlled by a circuit is additionally connected to a vent pipe, an outlet of the pump is connected to a jet, and the pump sucks a water flow through an intake pipe while air is simultaneously sucked through the vent pipe to be mixed with the water flow in the pump. An outlet disk is configured in the jet, and pores are distributed on an outer circumference of the outlet disk. With the jet inside-out to transmit the air-mixing water flow, the air-mixing water flow is further compressed and released through the pores, thus to output water flows or the water columns carried with ultramicro bubbles.

A thin film transistor (TFT) formed on a substrate includes a polycrystalline film, a gate insulator, a hydrogen-supplying film and a gate electrode. The polycrystalline film is formed on the substrate. Two sides of the polycrystalline film serve as the source and the drain of the semiconductor device, and the central region of the polycrystalline layer serves as the channel. The gate insulator is formed on the polycrystalline film, then the polycrystalline film is ions implanted, and the hydrogen-supplying film is formed on the gate insulator. The gate electrode is formed on the hydrogen-supplying film above the channel. The hydrogen-supplying film supplies hydrogen to the polycrystalline film, especially to the channel, so as to transform the unsaturated bonds into hydrogen bonds in the channel for avoiding the unsaturated bonds to degrade the charge carrier efficiency of the channel.

An HDP-CVD system is described, including an HDP-CVD chamber for depositing a material on a wafer, and a pre-heating chamber disposed outside of the HDP-CVD chamber to pre-heat the wafer, before the wafer is loaded in the HDP-CVD chamber, to a temperature higher than room temperature and required in the deposition step to be conducted in the HDP-CVD chamber. The pre-heating chamber is equipped with a heating lamp for the pre-heating. The wafer has been formed with a trench before being pre-heated.

A wristwatch worn by a user for measuring a three-lead ECG includes three electrodes placed separately on the front, either side, and back or strap thereof. The wristwatch further includes an electrode panel having the electrode on the front or either side of the watch, sensing elements, pressure, infrared or impedance detectors, and circuits. The electrode panel is capable of sensing the contact or press of fingers to trigger the ECG measuring. While the electrode in the back-side of the watch contacts the hand wearing the watch, the electrode and electrode panel on the front or either side of the watch are pressed by fingers from the other hand, and the electrode in the strap contacts the abdomen or left leg simultaneously. Thus, a three-lead ECG can be measured. ECG data can be transmitted to a personal or hospital computer by wireless networks or flash memory.
