Filed: 2005-12-28
Abstract: A method for forming a dual gate in a semiconductor device is provided to obtain an optimum gate etch profile by applying optimum gate etch recipes to an NMOS and a PMOS having different etch ratios. An NMOS region and a PMOS region are defined on a semiconductor substrate(10). A gate insulating layer(20) is formed on the semiconductor substrate. A first polysilicon layer(30a) doped with N type impurity ions is formed on the gate insulating layer of the NMOS region. A second polysilicon layer(30b) doped with P type impurity ions is formed on the gate insulating layer of the PMOS region. A tungsten silicide layer(40) is formed on the first and second polysilicon layers. A hard mask layer is formed on each of the NMOS and PMOS regions of the tungsten silicide layer. A first mask pattern is formed to expose the PMOS region. The tungsten silicide layer, the second polysilicon layer, and the gate insulating layer of the exposed PMOS region are etched. The first mask pattern is eliminated. A second mask pattern(60b) is formed on the entire surface of the semiconductor substrate to expose NMOS region. The tungsten silicide layer, the first polysilicon layer, and the gate insulating layer of the exposed NMOS region are etched. The second mask pattern is removed.

Title: Scalable quality broadcast service in a mobile wireless communication network
Inventor: KHAN IRFAN
IPC: H04L12/56
Filed: 2004-04-01
Abstract: The quality of a broadcast stream is varied responsive to changes in the utilization of forward link air interface resources. The network monitors utilization of forward link air interface resources and dynamically changes the forward link air interface resources dedicated to the broadcast stream responsive to changes in the utilization of forward link air interface resources. The quality of the broadcast stream is scaled to the allocated forward link resources. The broadcast stream may include a layered content and scaling can be achieved by varying the number of layers transmitted over the air interface. The network may notify mobile stations in advance when changes in the quality of the broadcast will take place. When the broadcast stream originates with a mobile station, the forward link air interface resources may be limited by the quality of the broadcast stream transmitted over a reverse link channel from the originating mobile station.

Title: Interference and noise estimation in an ofdm system
Inventor: SUTIVONG ARAK
IPC: H04J11/00
Filed: 2004-05-14
Abstract: Noise and interference can be independently measured in a multiple user Orthogonal Frequency Division Multiplexing (OFDM) system (200). Co-channel interference is measured in a frequency hopping, multiple user, OFDM system by tracking the sub-carriers assigned to all users in a particular service area or cell (202). The composite noise plus interference can be determined by measuring the amount of received power in a sub-carrier whenever it is not assigned to any user in the cell. A value is stored for each sub-carrier in the system and the value of noise plus interference can be a weighted average of the present value with previously stored values. The noise component can be independently determined in a synchronous system. In the synchronous system, all users in a system may periodically be prohibited from broadcasting over a sub-carrier and the received power in the sub-carrier measured during the period having no broadcasts.
