Publication number: 20100193918Abstract: A system, method, and apparatus for suppressing cracks in the wafer dicing process. A wafer includes a plurality of die attached to a frame and mounting tape, with the die separated by a plurality of scribe lanes. An existing die seal generally protects the boundary of the die but can still fail to fully protect the die from excessive cracks induced by dicing damage, particularly when dicing through brittle, low-k dielectrics. The system, method, and apparatus includes embedding a crack arrest structure (CAS) between adjacent scribe lanes. Upon a mechanical saw dicing the wafer, the CAS creates a moisture diffusion block, and can absorb or significantly diminish the energy of cracks propagating towards the individual die seals. Furthermore, the system, method, and apparatus can be implemented without the need to increase the width of the scribe lanes.Type: ApplicationFiled: February 4, 2009Publication date: August 5, 2010Inventors: Jeffrey A.

Patent number: 7708947Abstract: The present invention relates to methods of making compositions for sensor films used for detecting chemical analytes within sensors, such as polymer-absorption chemiresistors (i.e., conductometric sensors). The sensor films have reduced cross-sensitivity to temperature, while maintaining sensitivity to the chemical analytes. The sensor matrix includes components that are associated with a first temperature coefficient of resistance, such as a polymer resin and/or a first conductive particle. The sensor matrix further comprises a second species, preferably a conductive particle, which has a second temperature coefficient of resistance that is opposite to the first temperature coefficient of resistance. The second species has an opposite influence on a resistance response of the sensor from the first species. In this manner, the sensor matrix exhibits a minimized response in resistance to any changes in temperature.Type: GrantFiled: November 1, 2005Date of Patent: May 4, 2010Assignee: Therm-O-Disc, IncorporatedInventors: Jeffrey A.

Publication number: 20100078769Abstract: In a semiconductor device for use in a wafer level chip scale package (WLCSP) and a method for fabrication, an inner scribe seal is formed around a functional circuit area that does not extend all the way into the corners of the rectangular die, and an outer scribe seal follows the perimeter of the die and into the corners, with the outer scribe seal having a continuous barrier wall towards the die edges so that moisture penetration in dielectric layers of the die is minimized, and cracks and delamination are stopped near the die edges. Limiting the extent of the insulating layer or layers in the WLCSP to cover the functional circuit area also reduces the stresses caused by these layers near the die corners. Other features further enhance the strength and barrier properties of the scribe seals and the layers near the die corners, terminate cracks and delamination at various levels within the dielectric stack of the die and the die protective overcoat, and prevent damage during the WLCSP assembly process.Type: ApplicationFiled: September 23, 2009Publication date: April 1, 2010Applicant: TEXAS INSTRUMENTS INCORPORATEDInventors: Jeffrey A.

Publication number: 20090004612Abstract: A gas-fired heating appliance includes a burner, a gas valve module for supplying a fuel gas to the burner, a power module for applying a voltage to the gas valve module, and a flammable vapor sensor module for detecting a flammable vapor. The flammable vapor sensor module interrupts the voltage to the gas valve to shut off the gas valve and the burner when the flammable vapor module detects the presence or a predetermined concentration of flammable vapor. The voltage of the power module is applied to the gas valve module through the flammable vapor sensor module. The voltage to the gas valve module is interrupted if the flammable vapor sensor module is short-circuited. This arrangement is tamper-resistant to promote a safe operation of the gas-fired heating appliance.Type: ApplicationFiled: June 28, 2007Publication date: January 1, 2009Applicant: THERM-O-DISC, INCORPORATEDInventor: Jeffrey A.

Patent number: 7265560Abstract: A chemiresistor sensor system that compensates for changes in resistance caused by changes in ambient temperature, thereby increasing the accuracy of the sensor system's ability to detect target analytes. The sensor system generally includes a first resistor, a second resistor, and a load regulator or switch that is sensitive to changes in ambient temperature. At least one of the first resistor and the second resistor is a sensing element having a resistance that changes in response to the presence of one or more of the analytes. The switch manages an electrical load across the first resistor and the second resistor. The switch prevents passage of the electrical load across the first and/or second resistor when the ambient temperature is at a first value. The switch permits passage of the electrical load across the first and/or second resistor when the ambient temperature is at a second value.Type: GrantFiled: November 23, 2005Date of Patent: September 4, 2007Assignee: Therm-O-Disc, IncorporatedInventors: Jeffrey A.

Publication number: 20060157999Abstract: The invention consists of a gripping device with two flat handles permanently secured together such that the flat sides are adjacent and freely pivot around a fastener. The ends farthest from the pivot point comprise a handle to be squeezed in the hand. The other ends are each bent and twisted in such a manner that one handle can pivot under the other handle, while the bends create a pair of matching jaws. The jaws are placed around a hot cooking utensil or other object and the handles are squeezed in the hand, thus firmly gripping the hot item, which can then be safely moved as desired without the user sustaining a burn.Type: ApplicationFiled: January 13, 2006Publication date: July 20, 2006Inventor: Jeffrey West
