Title: Method of, and system for, transmitting messages
Inventor: BELL JOHN RICHARDSON
IPC: H04W84/02
Filed: 1997-11-21
Granted: 1999-06-21
Abstract: A message transmission system comprising at least one primary station having means for making transmissions on a down-link and a plurality of secondary stations having means for making transmissions on an up-link in response to an invitation issued by the primary station on the down-link. Each of the secondary stations has means for generating responses to messages as pseudo-random data sequences. The generation of these responses commences at an integer multiple of a unit time period after a time reference determined with respect to the invitation signal. A secondary station may wish to transmit a second or a further response signal associated with the originally received message and for which no invitation is issued. Said second or further response signal is transmitted at a point in time which is another integer multiple of the unit time period after the said time reference.

Title: System and method for optimum high speed data transmission
Inventor: SCHOLTZ WILLIAM H
IPC: H04L7/033
Filed: 1998-08-25
Granted: 2000-04-01
Abstract: The present invention is drawn to a system and a method for transmitting data signal using digital subscriber loops in an expanded frequency band. According to the present invention, an encoder receives data signal before transmitting the signal to a second modem. The encoder generates both in-phase and quadrature signals based on the data signal. Both the in-phase signal and quadrature signals are then processed by a signal precoder in preparation for the transmission through a channel. Next, the in-phase and quadrature signals are processed by a digital filter to produce signals of limited bandwidth which can be transmitted across the channel. The coefficient of the digital filter is chosen such that the resulting filtered in-phase and quadrature signals are transmitted in an expanded bandwidth. The quadrature signal is filtered so as to be orthogonal to the in-phase signal. Thereafter the filtered signals are added and then converted to an analog signal which is transmitted to the second modem. The second modem features signal recovery circuitry which will process the expanded bandwidth resulting in a baseband which features an increased signal to noise ratio making the data transmission less susceptible to interference.

Title: A method of fabricating a semiconductor device
Inventor: CHOI CHANG-WON
IPC: H01L21/302
Filed: 1999-04-23
Granted: 2003-09-11
Abstract: A method of fabricating a semiconductor device having a contact plug in which a damage layer on an upper surface of the contact plug is dry etched using an oxygen gas or a mixed gas containing an oxygen gas and a fluorine including gas for example CF4, C2F6, CHF3 and NF3. A contact hole is opened in a first insulating layer to an active device region of a semiconductor substrate. The contact hole is filled up with a polysilicon layer. The polysilicon layer outside the contact hole is then etched back (plasma process) to form a contact plug. However, in this step, the damage layer is formed on the contact plug due to accelerated ions caused by a plasma energy. The dry etch process is performed to remove the damage layer on the surface of the contact plug. In the improved present invention, the dry etch technique is adopted to remove the unwanted damage layer on the surface of the contact plug to reduce the contact resistance between the contact plug and the overlying a conductive layer.

Title: Pay broadcasting system with enhanced security against illegal access to a down loaded program in a subscriber terminal
Inventor: HARADA TAKENOSUKE
IPC: H04N7/167
Filed: 1999-07-01
Granted: 2000-12-21
Abstract: In a pay broadcasting system, data of a broadcast program is scrambled with a scramble key updated in a short period. The scramble key is encrypted with a first key assigned to the subscriber terminal. The first key is encrypted with a first master key set in the subscriber terminal. The security of a broadcast program stored for subsequent use in the subscriber terminal is enhanced as follows. A central station generates a second key-encrypted scramble key by encrypting the scramble key with a second key different from the first key and changeable in an interval shorter than a update interval of the first key; generates an encrypted second key by encrypting the second key with a second master key which has been commonly issued to subscriber terminals of the system; and broadcast the second key-encrypted scramble key and the encrypted second key together with the scrambled data of the program, the first key-encrypted scramble key and the encrypted first key in a multiplexed manner. When a broadcast program is to be stored, the subscriber terminal stores the scrambled data of the broadcast program and the second key-encrypted scramble key; decrypt the encrypted second key with the second master key into the second key, which is added to a stored program second key list. If the stored program is to be executed, the second key-encrypted scramble key is decrypted with a corresponding one of the second keys in the stored program second key list into a decrypted scramble key; and the scrambled data of the broadcast program is unscrambled with the decrypted scramble key.

Title: Indium-enhanced bipolar transistor
Inventor: JOHANSSON TED
IPC: H01L29/167
Filed: 1999-10-19
Granted: 2001-05-01
Abstract: A method to improve the characteristics of bipolar silicon high-frequency transistor by adding indium into the base of the transistor is described. Instead of replacing boron in the base with indium to improve the beta-Early voltage product, at the price of high beta and high base resistance, separate boron and indium doping profiles are combined in the base. Thus, a transistor which preserves most of the properties of pure boron-base transistor is obtained, but with some parameters improved due to the added indium profile. This ""double-profile"" or ""indium-enhanced"" transistor exhibits improved beta-Early voltage product, reduced collector-base capacitance swing and lower temperature dependence of beta, but preserves the advantageous properties of a pure boron-base transistor. For this to work satisfactory, the indium profile must be contained within the boron profile in such a way that the beta and the effective base width are not significantly afected, otherwise the high frequency properties will be degraded. A typical process for fabricating a bipolar silicon high frequency NPN transistor together with some recorded parameters highlighting the benefits of an additional indium implant is presented.

Title: Manufacturing method of DRAM capacitor
Inventor: JAN BO-WEN
IPC: H01L27/108
Filed: 1999-12-10
Granted: 2001-01-21
Abstract: A manufacturing method of DRAM capacitor comprises the following steps. First, a substrate is prepared, which has an oxide layer formed thereon a poly-silicon layer. A plug is provided under the poly-silicon layer for passing through the oxide layer. Then, a patterned photo-resistor (PR) layer is formed on the poly-silicon layer and the side portion of the PR layer is chemically reacted to form a sidewall with a low etching rate. The non-reacted PR layer and the poly-silicon layer under the PR layer opening are removed by dry etching. Then, the sidewall is used as a mask to keep on dry etching to remove a portion of the poly-silicon layer under the PR layer. Finally, the PR sidewall is stripped off to complete the manufacturing process of crown-type capacitor.
