Computer resource leak detection
Various embodiments discussed herein enable intelligent resource leak detection and associated user interface. In some aspects, if a kernel sends a tracing event (e.g., an ETW event) after a process or application has been requested to be shut down but before the process has actually been shut down, a resource leak can be detected. This is because the application should have requested the reference indicator to be removed in memory before the tracing event, as opposed to the kernel acting alone without an application request to remove the reference indicator. If a reference indicator has not been requested to be removed by the time this tracing event occurs, then it is indicative of the application never having sent a request to remove the reference indicator, which is indicative of a resource leak. |

Offset corrected bandgap reference and temperature sensor
An offset corrected bandgap reference and temperature sensor is disclosed. In a complementary metal-oxide-semiconductor (CMOS) bandgap reference, non-idealities in the operational amplifier (op-amp) bandgap reference circuit can lead to a voltage offset. This operational amplifier offset voltage is the dominant source of error in the bandgap reference. If the bandgap reference is used in a temperature sensor, it only needs to be accurate during the analog-to-digital conversion cycle. Embodiments of the present disclosure employ switched capacitors to store the operational amplifier offset during a sample mode in which the bandgap reference operates continuous-time. The operational amplifier offset is then corrected during a hold mode while the temperature sensor completes the analog-to-digital conversion. |

Apparatus with multistaged cooling
Embodiments described herein relate to a heat exchanger for abating compounds produced in semiconductor processes. When hot effluent flows into the heat exchanger, a coolant can be flowed to walls of a heat exchanging surface within the heat exchanger. The heat exchanging surface can be a curved shaped which creates a multi stage cross flow path for the hot effluent to flow down the heat exchanger. This flow path forces the hot effluent to hit the cold walls of the heat exchanging surface, significantly cooling the effluent and preventing it from flowing directly into the vacuum pumps and causing heat damage. Embodiments described herein also relate to methods of forming a heat exchanger. The heat exchanger can be created by sequentially depositing layers of thermally conductive material on surfaces using 3-D printing, creating a much smaller foot print and reducing costs. |
