Title: Method of cleaning an inter-level dielectric interconnect
Inventor: FANG SUNFEI
IPC: H01L21/768
Filed: 2002-08-22
Granted: 2003-10-21
Abstract: A method for cleaning a semiconductor interconnect structure formed in an organic ILD using an anisotropic organic dielectric etch in combination with a sputter clean process. Organic material displaced from the sidewalls to the bottom of the structure by the sputter clean is removed by the ion enhanced organic etch. Interconnect resistance shift is reduced and reliability of the interconnect structure is improved by removing contaminates at the interface of the via/contact, and by increasing adhesion of the liner or plug to the underlying conductive layer.

Title: Test array and method for testing memory arrays
Inventor: TRAN LUNG T
IPC: G01R31/28
Filed: 2002-08-29
Granted: 2003-12-01
Abstract: A test array (100, 200) includes row conductors (110, 210), column conductors (120, 220), and memory cells (130, 230) located at crossing points of the row and column conductors. The test array (100, 200) can have groups (124, 214, 224) of the row conductors (110, 210) or the column conductors (120, 220) electrically coupled, or ganged together, so that they share common terminals (216, 226). Other selected row and column conductors can have individual terminals (112, 122, 212, 222). In this configuration, memory cells (130, 230) located at the intersection of row and column conductors that have individual terminals (112, 122, 212, 222) can have their characteristics measured using a test apparatus. Ganging together groups of row or column conductors means that the test array has (100, 200) fewer terminals for connection to the test apparatus. Therefore, a test apparatus having a limited number of probes for connection to test array terminals can be used to test arrays (100, 200) of various sizes.

Abstract: A routing method is used to execute a router, which provides a complete routing table and multiple routing cache memories. The routing table comprises the following procedures; firstly the router utilizes multiple routing cache memories as first to mth cache routing tables, where m is positive integer. The kth cache routing table stores prefix with multiple Lk bits, where 1 <= k <= m and k is positive integer and 0 < L1 < L2 < ... < Lm. While receiving a network packet with Lm bits of destination address, search the first Li bits of the destination address in the ith cache routing table, where 1 <= i <= m and I is positive integer. When the prefix with the first identical Ln bits of the destination address is found in the nth cache routing table, send out the network packet in accordance with the corresponding routing information of the routing prefix, where 1 <= n <= m and n is positive integer.
