  • Publication number: 20030122843
    Abstract: A method and apparatus to obtain a substantially accurate digital color image of a subject at relatively low cost. A moveable enclosure containing a controlled lighting source provides a controlled lighting environment that costs considerably less than a traditional photo studio and is more convenient to use for many applications. A digital color image capture device captures an image of a subject in the enclosure. The captured image is sent to a computer where a stored color profile previously obtained from a calibration of the digital image capture device is used by a software program to automatically correct the color of the captured image. The color-corrected image can then be distributed to other computers for display.

  • Publication number: 20020196882
    Abstract: The present invention provides a transmission method capable of synchronously transferring information in many ways to simultaneously transfer data to plural receivers. In the transmission method of the present invention, a control menu and data to be transferred are first provided, and predetermined receivers are then selected. Next, an image capturing device is used to scan the control menu and the data to be transferred and convert them into an electric signal, which is then transferred to a computer server. The computer server discriminates the electric signal and converts it into an image signal. If the result of discrimination is successful, the image signal is transferred to an FTP server or a client computer so that the receivers can receive the image signal in predetermined ways of reception. The present invention has the characteristics of synchronous and manifold transmission, fast transmission, and convenient use.

  • Publication number: 20020120788
    Abstract: A method and system may process messages in real time. The computer may analyze the received message in advance when receiving a message from the sender, which means the computer may determine whether or not the received message is the specific message which needs to be processed in real time. If the received message is specific, then, according to the setting reminding method, the system may utilize shaking of the mouse, sending out voice or light or displaying an image on the screen to remind the users. The users thus may respond to the message immediately, which may eliminate the delay of the important message.

  • Publication number: 20020110285
    Abstract: A method and system for managing a digital image using online driving from a network are disclosed. A digital image is formed by a capturing device and then is stored in a first memory of the capturing device. Afterwards, a program media automatically diagnoses the capturing device and then installs a driver corresponding to the capturing device for online driving of the capturing device. The digital image in the first memory is uploaded to a second memory of the image server, and therefore the capacity of the first memory is completely released. Thereafter, the digital image is properly edited and is stored in the second memory to manage and distribute with respect to the digital image. Finally, a remote PC is linked to the image server via the Internet for selectively downloading the digital image saved in the secondary memory.

  • Patent number: 6271079
    Abstract: The present invention provides a method of forming trench capacitor with a sacrificial silicon nitride. A deep trench structure is formed in a substrate. A TEOS oxide layer is formed on the substrate and filled in said trench region, etched to a first level subsequently, wherein a portion of the TEOS oxide layer is remained in the trench region and a portion of the substrate exposed to form a trench sidewall. A thermally oxidation process is performed to form a collar oxide on the exposed substrate. A silicon nitride sidewall is formed on the collar oxide, then removing the residual TEOS oxide layer by wet etching. The trench region is then etched using the silicon nitride sidewall as a barrier to form a bottle shape trench region for increasing the surface of the trench region. A bottom cell plate is formed in the fresh trench region. The silicon nitride sidewall is removed.

  • Patent number: 6261926
    Abstract: The present invention provides a method for fabricating a field oxide on a semiconductor substrate. A first pad layer and a first mask layer is formed successively on the semiconductor substrate. An opening is formed in the first mask layer to define a region for forming the field oxide. A first field oxide is formed in the opening, which is then removed to form a concave portion. The first pad layer exposed by the concave portion is removed to form a cavity. A second pad layer having a smaller thickness than the first pad layer is formed on the semiconductor substrate. A mask portion is formed in the sidewall of the patterned first mask layer and the cavity. The mask portion in the sidewall of the patterned first mask layer has a thickness less than 300 Å. Finally, thermal oxidation is carried out to form a second field oxide in the concave portion.

  • Patent number: 6255188
    Abstract: A method of removing a polysilicon buffer in a method of forming a field oxide and an active area is disclosed herein that comprises the step of applying an etching selectivity solution to the polysilicon buffer to substantially remove the polysilicon buffer without substantially affecting the field oxide, a pad oxide, and the substrate. An etching selectivity solution is defined herein is a solution that has an etching rate for one material that is higher than for another material. In this case, the etching selectivity solution has an etching rate for polysilicon material that is higher than its etching rate for field oxide material. Accordingly, when the etching selectivity solution is applied to the polysilicon buffer, it will substantially etch off the polysilicon buffer without substantially affecting the field oxide. In the preferred embodiment, the etching selectivity solution comprises a mixture of HF and HNO3, or HF, HNO3 and CH3COOH.

  • Patent number: 6242357
    Abstract: A method of forming a DRAM cell with a trench capacitor over a semiconductor substrate comprises the following steps. First, an etching step is performed to form a trench structure in the substrate, wherein the trench structure has a bottom and sidewalls, and the sidewalls are adjacent to the bottom. Then, the trench structure is doped to form a doping region on the bottom and a portion of the sidewalls. A selective etching step is performed to remove a portion of the doping region, wherein a selectivity of the doping region is higher than that of undoped sidewalls. A dielectric layer is formed on a top surface of the trench structure. A conducting layer is then formed in the trench structure. Next, a gate structure is formed on the substrate. A doping step is used to form the drain/source structures adjacent to the gate. A strap region is formed to couple the conducting layer and the drain/source structures.
