Patent number: 7189615Abstract: The formation of a MIM (metal insulator metal) capacitor (164) and concurrent formation of a resistor (166) is disclosed. A copper diffusion barrier (124) is formed over a copper deposition (110) that serves as a bottom electrode (170) of the capacitor (164). The copper diffusion barrier (124) mitigates unwanted diffusion of copper from the copper deposition (110), and is formed via electro-less deposition such that little to none of the barrier material is deposited at locations other than over a top surface (125) of the deposition of copper/bottom electrode. Subsequently, layers of dielectric (150) and conductive (152) materials are applied to form a dielectric (172) and top electrode (174) of the MIM capacitor (164), respectively, where the layer of conductive top electrode material (152) also functions to concurrently develop the resistor (166) on the same chip as the capacitor (164).Type: GrantFiled: January 18, 2005Date of Patent: March 13, 2007Assignee: Texas Instruments IncorporatedInventors: Satyavolu Srinivas Papa Rao, Darius Lammont Crenshaw, Stephan Grunow, Kenneth D.

Patent number: 7189627Abstract: A technique is disclosed for increasing the width of a transistor (300) while the transistor itself may be scaled down. The transistor width (382) is increased by forming recesses (352) within shallow trench isolation (STI) regions (328) adjacent to the transistor (300). The recesses (352) provide an area that wraps around the transistor and thereby increases the width (382) of the transistor (300). This wraparound area provides additional space for dopant atom deposition, which facilitates a reduction in random dopant fluctuation (RDF). In this manner, transistors formed in accordance with one or more aspects of the present invention, may yield improved performance when incorporated into SRAM since the probability that such transistors will be more closely matched is increased.Type: GrantFiled: August 19, 2004Date of Patent: March 13, 2007Assignee: Texas Instruments IncorporatedInventors: Zhiqiang Wu, Shaofeng Yu, C.

Patent number: 7190541Abstract: A write driver (38) produces balanced voltages across head (32) by using the input write data (WDX and WDY) drive transistors of a slower transistor type (typically PNP) on one half of an H-bridge configuration, while transistors of a faster transistor type (typically NPN) in the other half of the H-bridge configuration are driven indirectly by transistors of the slower type, with a trans-resistance in series with transistors of the faster type. Accordingly, the voltage nodes on either side of the write head are pulled to Vcc and Vee symmetrically. A trans-resistance block (40) uses current sources to pull current from capacitive nodes for faster switching.Type: GrantFiled: March 14, 2006Date of Patent: March 13, 2007Assignee: Texas Instruments IncorporatedInventors: Jeremy Kuehlwein, Scott Sorenson

Patent number: 7191162Abstract: The invention describes a modification of FIFO hardware to allow improved use of FIFOs for burst reading from or writing to a processor direct memory access unit via either an expansion bus or an external memory interface using FIFO flag initiated bursts. The hardware and FIFO signal modifications make the FIFO-DMA interface immune to deadlock conditions and generation of spurious interrupt events in the process of initiating burst transfers. The FIFO function is modified to synchronize the frame transfer on the digital signal processor even if the digital signal processor lacks this functionality. By delaying the programmable flag assertions within the FIFO until after the current burst is complete the DSP-FIFO interface may be made immune to deadlock conditions and generation of spurious events.Type: GrantFiled: October 21, 2003Date of Patent: March 13, 2007Assignee: Texas Instruments IncorporatedInventors: Clayton Gibbs, Kyle Castille, Natarajan Kurian Seshan
