Title: Method of forming self-aligned rugged crown-shaped capacitor of high-density dynamic random access memory
Inventor: WU SHIE-LIN
IPC: H01L27/108
Filed: 1999-05-13
Granted: 2001-03-11
Abstract: The method of this invention is described as follows. At first, the first oxide layer is formed on substrate and is followed by the formation of nitride layer on top of the first oxide layer. The second oxide layer is formed on top of nitride layer and the first silicon layer on the second oxide layer. An electrode opening is defined inside the first silicon layer, the second oxide layer and nitride layer. The sidewall structure is then formed on both sides of electrode opening. A contact opening is defined inside the first oxide layer and the sidewall structure as well as the nitride layer near the part of electrode opening are stripped off in order to form bottom-cut structure under the second oxide layer. The second silicon layer is formed to uniformly cover inside the contact opening, inside the bottom-cut structure, inside the electrode opening and on the first silicon layer. After that, a filling and leveling layer is formed on the second silicon layer. A planarization process is performed onto substrate to planarize till the position of the second oxide layer surface. The filling and leveling layer and the second oxide layer are stripped. Wet etching process is used to remove nitride layer and make the second silicon layer surface become rugged. A dielectric layer is formed to uniformly cover on the second silicon layer. Finally, a conduction layer is formed on top of the dielectric layer.

Title: System and method for switching packets in a network
Inventor: SCHWARTZ STEVEN J
IPC: H04L12/56
Filed: 1999-08-24
Granted: 2001-10-21
Abstract: A switching node for transferring packets, each including a destination address, in a network includes a plurality of input port modules, a plurality of output port modules and a switching fabric, including a packet meta-data processor and a packet switch. Each input port module is connected to a communication link for receiving packets thereover, and each output port module is connected to a communication link for transmitting packets thereover. Each input port module, upon receiving a packet, buffers the packet and generates a meta-data packet therefor identifying the output port module that is to transmit the packet and packet identifier information, and provides it to the packet meta-data processor. The packet meta-data processor receives the meta-data packets generated by all of the input port modules and operational status information from all of the output port modules and for each output port module, processes the meta-data packets received from all of the input port modules in connection with the operational status information to determine whether the packet should be passed or dropped. If the packet meta-data processor determines that a packet associated with a meta-data packet is to be dropped, it will notify the input port module in which the packet is buffered, which, in turn, will discard the packet. On the other hand if the packet meta-data processor determines that the packet associated with the meta-data packet is not to be dropped, it will enqueue the meta-data packet for the associated output port module. Each output port module retrieves meta-data packets from its respective meta-data packet queue maintained therefor by the packet meta-data processor. For each meta-data packet retrieved by an output port module, the output port module will request that the input port module identified in the meta-data packet transfer the packet identified in the input port module thereto through the packet switch. When the output port module receives the packet, it will transmit it over the communication link connected thereto.

Title: The pulley weight-division type double path optical mechanism
Inventor: CHANG TONY
IPC: G02B26/10
Filed: 1999-08-18
Granted: 2001-05-01
Abstract: The present technology is installing the dynamic force device on one of the two moving modules of double path optical mechanism. By using the principle of pulley weight-division and matching with the special arrangement of the belt or steel wire etc., it can transform the dynamic force so that the ratio of the moving speed of the fast moving module to the slowly moving module is 2:1. Since the dynamic force device is installed on the moving module, the vibration generated when the moving module slides can be absorbed by belt or steel wire, etc. Therefore, the whole product can have low-noise effect. Also, since the dynamic force device is installed on the moving module to make avail of the unoccupied space of the moving module, the vertical thickness of the whole product can be reduced compared to that of the well-known technology in which the dynamic device is installed on the bottom of the case body.

IPC: G11C11/22
Filed: 2000-02-09
Granted: 2001-12-01
Abstract: A ferroelectric capacitor is provided that can write ROM data at a manufacturing process, change the data after that, and restore the rewritten initial data. The ferroelectric memory device composing a memory cell, in which ferroelectric capacitors are provided, the memory cell includes ferroelectric capacitors each having a different hysteresis characteristic. The capacitor having the different hysteresis characteristic is formed at a manufacturing process as ROM data. The initial ROM data written at the manufacturing process can be restored and can be recorded as a polarizing direction by employing the difference between the hysteresis characteristics. In addition, the recorded data can be freely rewritten by a normal writing method and the recorded data can be maintained even when a power is OFF. Even after the initial ROM data is changed, the initial ROM data can be restored or recovered by employing the above-described different hysteresis characteristic.

Title: Method for preparing melamine
Inventor: TJIOE TJAY TJIEN
IPC: C07D251/60
Filed: 2000-02-15
Granted: 2007-02-01
Abstract: Method for preparing melamine from urea via a high-pressure process in which solid melamine is obtained by transferring the melamine melt to an expansion vessel where the melamine melt is cooled by incorporated ammonia. Excess ammonia gas is added to the melamine melt to produce a gas/liquid mixture having a mass ratio of at least 0.01. This two-phase mixture is then sprayed via a spraying means into an expansion vessel, the expansion vessel having an ammonia environment with a reduced ammonia pressure. The melamine melt is cooled and solidified by the expansion and evaporation of the incorporated ammonia to form melamine powder. The melamine melt is thereby directly converted into a melamine powder after which the melamine powder is cooled further and the ammonia pressure is released.

Title: Semiconductor storage device
Inventor: NAGATOMO MASAHIKO
IPC: G11C16/10
Filed: 2000-03-14
Granted: 2003-03-21
Abstract: A semiconductor storage device is disclosed in the present invention. When writing data into a memory cell 11 is completed and a reset signal RST is set to an ""H"" level, a control voltage MCD outputted by a write control circuit 30 is set to a ground voltage GND to start a discharge of the electrical charge on the drain line DL. When a specific length of time has elapsed, a reset signal RST1 outputted by a delay circuit 50 is set to an ""H"" level, and an output signal from a data writing circuit 40 is set to the ground voltage GND to start a discharge of the electrical charge on a source line SL. Since the electrical discharge at the drain line DL starts earlier than the discharge of the source line, the difference in the potential between the drain and the source in the memory cell 11 during a reset operation does not increase, thereby ensuring that no electrical current flows to the memory cell 11. Consequently, an erroneous data writing and a delay in access occurred due to an increase in the threshold voltage can be prevented.
