Title: Method for manufacturing self-aligned contact and silicide gate electrode
Inventor: WEN WEN-YING
IPC: H01L21/28
Filed: 1998-10-19
Granted: 2000-10-11
Abstract: According to this invention, there is formed firstly a thin oxide layer, a polysilicon layer, and a metal layer on a semiconductor substrate in sequence. Secondly, a mask is used to define and etch the polysilicon layer and the metal layer to form a gate electrode structure. After the gate electrode going through the thermal process, the oxygen content is provided so that the metal layer reacts with the adjacent polysilicon layer to form the silicide layer. The gate electrode structure comprises a polysilicon layer, a silicide layer, and a protective layer. After alternately executing the processes of ion implantation and spacer formation, the diffusion areas of the source and drain of the transistor form a gate electrode structure on the relative sides of the substrate. Further, a contact window is formed on the protective layer by etching, and the conductive layer is used to connect the gate electrode silicide in the contact window with the doped diffusion areas of the source/drain in the substrate. Finally, the processes of planarization and lead layout are performed.

Title: A clock phase correction circuit
Inventor: SUNG JUN-BAE
IPC: H03K5/13
Filed: 1999-05-25
Granted: 2000-12-11
Abstract: A clock phase correction circuit for a semiconductor memory device reduces all lock ranges by using a half-mixer to a conventional delay locked loop (DLL) circuit, and thus generates a clock signal having a fast lock time and a very small jitter. In order to achieve this objective, a track portion having a plurality of phase converters  and one half-mixer is provided between an input terminal of external clock and an input terminal of a delay means of the conventional DLL circuit, and approaches the phase of the external clock to a phase of the feedback clock. A phase difference between the corrected signal and the feedback clock is then reduced by the conventional DLL circuit. As a result, lock time becomes shorter, and the magnitude of a jitter becomes reduced.

Title: Security protocols for end-to-end mobile users with double authentication
Inventor: JANG JEN-CHENG
IPC: H04L9/00
Filed: 1999-07-19
Granted: 2001-07-21
Abstract: In most of the proposed protocols so far, it has been assumed that the person using the mobile station is the registrar of the SIM card; as a matter of fact, the previous protocol for authentication and session key distribution is built upon this assumption. This way, the mobile user can only verify the identity of the owner of the SIM card. This means that the mobile user can only know that who registers the SIM card with which he communicates. To make sure that the speaker at the other end is the right owner of the SIM card, concept of the session password is involved to construct the end-to-end security authentication protocol. In the proposed protocol, each mobile user can choose a session password. When two mobile users want to communicate with each other, either user can request to perform a double authentication process. Only when both of the end users input the correct session passwords can the correct common session key be established.

Granted: 2002-01-21
Abstract: When an SOI substrate is produced in which a silicon layer is epitaxially grown on an insulating underlay such as a single crystal oxide substrate or an oxide layer stacked on a silicon substrate, a first silicon layer epitaxially grown on the insulating underlay is ion implanted to make a deep part of an interface of the silicon layer amorphous, and then annealed to recrystallize. Next, the silicon layer is heat treated to oxidize part of the surface side, and after the silicon oxide is removed by etching, a silicon layer is epitaxially grown on the remaining first silicon layer to form a second silicon layer. Subsequently, the second silicon layer is again ion implanted to make a deep part of an interface amorphous, and then annealing is performed to recrystallize. With this method, an SOI substrate, which is very small in crystal defect density of the silicon layer and good in surface flatness, can be produced. Therefore, on the semiconductor substrate according to the present invention, an electronic device or optical device having high device performance and reliability that cannot be obtained with prior art device can be realized.

Title: Apparatus and method for forming cap
Inventor: BIETZER STEVEN H
IPC: B67D3/00
Filed: 1999-10-07
Granted: 2001-06-16
Abstract: A mold for injection molding of a plastic bottle cap has a cavity which defines the outside slope of the top and skirt of the cap. A core and a core insert fixed to the top of the core define the inside of the cap and constitute a single, non-moving part. A tapered stripper ring below the cavity engages the base of the cap skirt. After the cap has been injected through a hot tip in the cavity, the cavity is retracted. The stripper ring is then elevated relative to the core by means of ejector pins. As this is proceeding, air is released under the top of the cap to break vacuum tending to hold the cap on the cap insert. The cap is thus ejected from the mold. A reduced cycle time is achieved. The wall thickness of the cap may be reduced, thus reducing material cost.

Granted: 2002-09-01
Abstract: A shopping bot uses real time agents that automatically contact disparate web pages representing vast variety of different categories and merchants and retrieve and unify the information therein for display when a request for the information is made. Consequently, there is no need to create a ""wrapper"", or a ""information adapter"" for each category or each merchant because the same agent can retrieve and process information in various formats. In particular, the shopping bot generates queries from keywords entered by a user and a database of URL information. Information returned by the queries is filtered, parsed and mapped to a standard format. The formatted information can then be displayed. Since the information is converted to the standard format in real time, the invention allows quick addition of online merchants and additional product categories can be added quickly and easily. Further, information about a product item can be easily enlarged as market needs increase without changing a database of codes one-by-one. In accordance with one embodiment, the database of URL information includes URLs specific to site directories at each merchant site so that queries can be easily generated by appending user-provided keywords.
