Patent number: 7569486Abstract: A system and method of preventing pattern lifting during a trench etch/clean process is disclosed. A first layer comprising a first dip is formed over a first via pattern. A trench resist layer is formed. The trench resist layer is patterned with a trench reticle to produce a second via pattern in the trench resist layer over the first via pattern. A photo resist over the first via pattern is opened during a trench processing. Thus, an additional pattern added on a trench pattern reticle is used to open, i.e., remove resist over, a huge via feature area causing under layer dip.Type: GrantFiled: May 9, 2007Date of Patent: August 4, 2009Assignee: Texas Instruments IncorporatedInventors: Yong Seok Choi, Jeannette Michelle Jacques

Patent number: 7567105Abstract: A CAN receiver architecture design that provides better immunity against EMI interference than conventional designs is disclosed herein. This CAN receiver includes a voltage divider network connected to a front-end amplifier for dividing down the input signal from a two wire line by a predetermined amount and amplifying the signal by the same predetermined amount. The front-end amplifier generates the common-mode voltage of the input signal for a reference generator that determines the logic level of the incoming signal and subtracts a bandgap voltage reference from the common-mode voltage. A comparator compares the difference between the output of the front-end amplifier and the resultant signal generated by the reference generator to generate an output signal for the receiver. This CAN receiver architecture is faster than conventional designs and possesses an improved common-mode rejection, while operating over a wide input common mode range.Type: GrantFiled: December 23, 2005Date of Patent: July 28, 2009Assignee: Texas Instruments IncorporatedInventors: Narasimhan R.

Patent number: 7565995Abstract: While fabricating a packaged semiconductor chip, a wire is bonded on a chip contact pad using a wire bonding machine. A bond head of the wire bonding machine is moved relative to the chip contact pad, thereby pulling a first length of the wire out of the wire bonding machine. Part of the wire passes through a space between a first outer edge of a first bearing race and a second outer edge of a second bearing race during the pulling of the first length. The wire is bonded on a lead. A first piezoelectric element is energized in the bond head, thereby causing it to expand and press against the first bearing race, which brakes the first bearing race and brakes the wire between the first and second races. The bond head is moved relative to the lead during the braking and severs the wire proximate to the lead.Type: GrantFiled: January 13, 2006Date of Patent: July 28, 2009Assignee: Texas Instruments IncorporatedInventor: Scott Anthony Delmont

Patent number: 7567116Abstract: A voltage converting circuit and a battery device, aimed at the problem that the breakdown voltage required for the driving input of the selected switch element is increased as the potential of the selected power storage device is increased when a power storage device is selected from a plurality of power storage devices that are connected in series.

Patent number: 7567624Abstract: A system and method of data communication uses variable transmit antenna delays based on communication signal uplink measurements. The signals for each channel are delayed at baseband, so different delays can be used for each channel. The delay between each antenna are preferably chosen so that the strongest paths do not overlap in order to implement full transmit antenna diversity. Where it is not possible to eliminate overlapping paths, the transmitted signals are recharacterized by phase shifts and/or amplitude scaling to derive signals that inherently possess the desired communication signal characteristics.Type: GrantFiled: March 16, 2000Date of Patent: July 28, 2009Assignee: Texas Instruments IncorporatedInventors: Timothy M.
