  • Publication number: 20240149396
    Abstract: A high-pressure liquid jet cutting system can include a hopper configured to contain an abrasive mixture that includes abrasive and an additive, and a cutting head configured to receive the abrasive mixture from the hopper and introduce the abrasive mixture into a high-pressure liquid jet. The system can further include a sensor configured to detect a characteristic of the abrasive mixture associated with the additive, and one or more processors operably connected to the sensor and configured to determine information about the abrasive based, at least in part, on the detected characteristic. The one or more processors can be configured to adjust or otherwise control operation of one or more components of the high-pressure liquid jet cutting system based, at least in part, on the information to, e.g., improve or optimize system performance.

  • Patent number: 9835716
    Abstract: A sensor comprising a light emitter and light detector directly covered and encapsulated by a layer of light blocking compound. The light blocking compound can be thick enough between the light emitter and light detector to block substantially all light emitted by the light emitter from reaching the light detector directly, but be thin enough above the light emitter and light detector to allow at least some level of light emitted by the light emitter to escape out of the sensor, be reflected by another object, re-enter the sensor, and survive passing through the light blocking compound to enter the light detector.

  • Patent number: 6232153
    Abstract: A plastic package assembly method suitable for ferroelectric-based integrated circuits includes a strict thermal budget that reduces the time at temperature for four key processing steps: die attach cures, die coat cures, molding cures, and marking cures. The plastic package assembly method uses low temperature mold and die coat materials, as well as low temperature curable inks or laser marking in order to minimize degradation of electrical performance, thus improving yields and reliability. The assembly method uses a snap cure die attach step, a die coat followed by a room temperature cure, and formation of the plastic package with room temperature curable molding compounds not requiring a post mold cure. Front and back marking of the plastic package is accomplished using either an infrared or ultraviolet curable ink followed by minimum cure time at elevated temperature, or by using laser marking.

  • Patent number: 6190926
    Abstract: A yield enhancement technique for integrated circuit processing which reduces the deleterious effects of H2O contamination which is absorbed by conventional dielectric films resulting in an undesired subsequent out-diffusion of hydrogen when the integrated circuit die is subsequently subjected to relatively high processing temperatures such as those experienced in CERDIP packaging. The technique disclosed comprises the formation of an interlevel dielectric layer having hydrophilic properties (for example, 7.5% phosphorus doped TEOS) at least partially surrounding a device on the integrated circuit which layer is then subjected to an annealing operation to drive off at least a portion of any moisture present therein.

  • Patent number: 5661730
    Abstract: A test method for ferroelectric memories includes the steps of: functionally testing the ferroelectric memories to determine functional yield; storing the ferroelectric memories for at least eight hours; writing an initial pattern into the ferroelectric memories; baking the ferroelectric memories; reading the initial pattern to determine same state yield; writing an inverse pattern into the ferroelectric memories; reading the inverse pattern to determine opposite state yield; and again writing the initial pattern into the ferroelectric memories. The steps of baking, reading the initial pattern and writing the inverse pattern, and reading the inverse pattern and writing the initial pattern are repeated for a number of test cycles. The ferroelectric memories are baked at a temperature of about 150.degree. C. for a predetermined duration that is incremented with each successive test cycle.
