A low pressure drop structured packing sheet with diversion windows, which are formed on both crests and troughs. When in the expanded state where the diversion window and packing sheet are flat on the same plane, the diversion window has an opening and a fan-shaped portion, with the area of the opening being 0%-1000% of that of the fan-shaped portion. Two side intersection lines between the fan-shaped portion and packing sheet is symmetrical with respect to a central folding line which divides the fan-shaped portion into a left part and a right part. The two side intersection lines intercept to each other with an angel of about 10°-170°. When in the operating state where the diversion window and packing sheet are partially folded towards opposite directions, the fluid at the trough flows to a crest of the other side of the packing sheet with the help of diversion windows, thus increasing the area of vapor-liquid mass transfer. Additionally, when liquid goes across the diversion window, liquid at the bottom of the layer flow becomes the liquid on the liquid film, hence effectively facilitating update of the liquid film and turbulence, increasing mixture between the liquid and vapor, and improving rate of the mass transfer between vapor and liquid.

The present invention discloses a method of fabricating dual trench isolated epitaxial diode array. This method starts with the formation of heavily-doped first conductivity type regions and heavily-doped second conductivity type regions on the substrate, followed by epitaxial growth, then the formation of the isolations between diode array word lines by deep trench etch and the formation of the isolations between bit lines vertical to deep trenches by shallow trench etch, and finally the formation of separate diode array cells in the regions enclosed by deep and shallow trench isolations by ion implantation. This invention also provides a method of preventing the crosstalk current between adjacent word lines and bit lines of epitaxial diode arrays isolated by foregoing dual shallow trenches. This invention can be used for diode-driven, high-density, large-capacity memory, such as phase change random access memory, resistive memory, magnetic memory and ferroelectric memory; the method thereof is completely compatible with conventional complementary metal-oxide semiconductor (CMOS) process, and because the diode arrays can be formed before the formation of peripheral circuits, no drift of peripheral circuits will be caused by the thermal process thereof, thereby solving the technical challenge of fabricating high-density, large-capacity embedded phase change random access memory.

This invention relates to a method of epitaxial growth effectively preventing auto-doping effect. This method starts with the removal of impurities from the semiconductor substrate having heavily-doped buried layer region and from the inner wall of reaction chamber to be used. Then the semiconductor substrate is loaded in the cleaned reaction chamber to be pre-baked under vacuum conditions so as to remove moisture and oxide from the surface of said semiconductor substrate before the extraction of the dopant atoms desorbed from the surface of the semiconductor substrate. Next, under high temperature and low gas flow conditions, a first intrinsic epitaxial layer is formed on the surface of said semiconductor substrate where the dopant atoms have been extracted out. Following this, under low temperature and high gas flow conditions, a second epitaxial layer of required thickness is formed on the structural surface of the grown intrinsic epitaxial layer. Last, silicon wafer is unloaded after cooling. This method can prevent auto-doping effect during the epitaxial growth on semiconductor substrate and thus ensure the performance and enhance the reliability of the devices in peripheral circuit region.

The present invention is directed to a device (or an apparatus) and a method for providing information about body fluids. The device is for measuring a body fluid discharged from a body of a user by putting a first disposable absorbent article having a predetermined absorbent capacity to a fluid discharging portion of the user. The device comprises means for inputting an amount of the body fluid which is absorbed by the first absorbent article through observation; and means for calculating the total amount of the body fluid which was discharged by the user based on the input and the predetermined absorbent capacity of the first absorbent article.

A system and method is used for transmitting an audio message by mobile phones during communication with a remote terminal. The system includes a detecting module, a storage module, a voice processing module, and an output control module. The detecting module detects whether the mobile phone is communicating with the remote terminal, and transmits a busy signal to the storage module when the mobile phone is communicating with the remote terminal. The storage module stores a plurality of digital voice signals, and transmits the corresponding digital voice signal to the voice processing module when receives the busy signal. The voice processing module converts the corresponding digital voice signal to audible voice message, and transmits the audible voice message to an output control module. The output control module transmits the audible voice message from the voice processing module to the remote terminal together with communicating voice message.
