Title: Built-in self-test circuit for RAMBUS DRAM
Inventor: HUANG SHI-YU
IPC: G01R31/28
Filed: 1999-05-26
Granted: 2001-03-11
Abstract: The present invention discloses a built-in self-test (BIST) circuit for RAMBUS DRAM. Unlike other usual memory devices, RAMBUS DRAM can perform its input stimuli in accordance with a complicated protocol at an extremely high operation speed (400 MHz). In order to perform a high-speed test, a new BIST structure is therefore required. The BIST structure consists of three key elements, including two interactive finite state machines and a high-speed time division multiplexer. The two finite state machines together define the potential test algorithm and generate the sequential memory commands. By means of the time division multiplexer, each memory command can further correspond to a multi-cycle package ideal for RAMBUS DRAM. Among these elements, the finite state machines often encounter operation bottlenecks. A simple master-slave synchronous mechanism may be applied to convert the two finite state machines into a multi-cycle path element as a solution for the time restriction.

It is isolated from this structure to prevent parallel-plate resonance modes from being set up. A separator layer (22) is fixed under the conductive layer to protect it from any capacitive coupling with other components of the device. It may be made of an insulating rigid foam. The invention applies to making a radiotelephone system.

Title: Method for improving copper damascene process by uniform titanium nitride layer
Inventor: SHIUNG JIUNG-SHENG
IPC: H01L23/52
Filed: 1999-08-03
Granted: 2001-04-21
Abstract: A method for improving a copper damascene process by adding a titanium nitride layer is disclosed. The present invention comprises inserting a titanium nitride layer formed by chemical vapor deposition between a dielectric layer and a copper seed layer. In the present invention, a titanium nitride layer can be formed between a barrier layer and a copper seed layer, or between a dielectric layer and a barrier layer. Since a chemical vapor deposition process has a better uniform coverage, the titanium nitride layer has a better step coverage capability and can be used as a reinforced barrier protective layer to effectively prevent the inter diffusion of copper. Furthermore, since copper can be directly formed on the surface of the titanium nitride layer, the present invention can improve the problem of void formation caused by the discontinuity of the copper seed layer. The present invention can greatly improve the formation of the copper conductive layer, as well as increase the performance of a copper damascene process.

Title: A quadrature modulator with set and forget carrier leakage compensation
Inventor: MOHINDRA RISHI
IPC: H03C5/00
Filed: 2000-03-29
Granted: 2002-07-11
Abstract: A quadrature modulator with set-and-forget carrier leakage compensation. The quadrature modulator comprises an in-phase and a quadrature branch. In the in-phase and quadrature branches, real-time digital signals are converted to analog signals, the analog signals are filtered, and the filtered analog signals are modulated with a carrier signal and a ninety degrees phase shifted version of the carrier, respectively. The modulated in-phase and quadrature signals are added so as to form a quadrature amplitude modulated signal. Preferably upon powering up of the quadrature modulator, in the in-phase and quadrature branches, carrier leakage is measured. The measured carrier leakage is supplied to comparators, which toggle, when carrier leakage is minimal in the respective in-phase and quadrature branches. Upon powering up of the quadrature modulator, the state machine starts signal generators which inject compensation signals into the in-phase and quadrature branches, respectively, so that dc-offsets in the in-phase and quadrature branches are reduced, thereby reducing the carrier leakage in the in-phase and quadrature branches. When the comparators toggle, the state machine is commanded to stop controlling the corresponding signal generators of which output signals are then frozen.
