Techniques for layer fencing to improve edge linearity
An ink jet process is used to deposit a material layer to a desired thickness. Layout data is converted to per-cell grayscale values, each representing ink volume to be locally delivered. The grayscale values are used to generate a halftone pattern to deliver variable ink volume (and thickness) to the substrate. The halftoning provides for a relatively continuous layer (e.g., without unintended gaps or holes) while providing for variable volume and, thus, contributes to variable ink/material buildup to achieve desired thickness. The ink is jetted as liquid or aerosol that suspends material used to form the material layer, for example, an organic material used to form an encapsulation layer for a flat panel device. The deposited layer is then cured or otherwise finished to complete the process. |

In further chipmaking process, defect generation as oxidation induced stacking faults—OISFs—during oxidation step is prevented. OISF are not generated even in metal contaminated wafers. As process does not includes high temperature anneal, RF SOI devices—like front chips of smartphones—made on these wafers have advanced RF performance. Process uses only standard equipment readily available at semiconductor foundries; therefore, the process can be easily implemented at foundries. |

Proactive impact analysis in a 5G Telco network
Examples herein describe systems and methods for impact assessment in a Telco network. An impact assessment engine can receive a scenario that species a symptom for a network resource. The scenario can be specified on an administrative console. The impact assessment engine can construct failure signatures in a codebook matrix. The codebook matrix correlates problems at impacted network resources to network symptoms. Based on the scenario, the impact assessment engine can generate synthetic failure signatures and isolate a subset based on which of the synthetic failure signatures are most common. Then, the system can identify tenants and services in the Telco network impacted by the subset. This can allow administrators or an automated process to identify potential impacts before a scenario occurs. |

Resource optimization for serverless query processing
A serverless query processing system receives a query and determines whether the query is a recurring query or a non-recurring query. The system may predict, in response to determining that the query is the recurring query, a peak resource requirement during an execution of the query. The system may compute, in response to determining that the query is the non-recurring query, a tight resource requirement corresponding to an amount of resources that satisfy a performance requirement over the execution of the query, where the tight resource requirement is less than the peak resource requirement. The system allocates resources to the query based on an applicable one of the peak resource requirement or the tight resource requirement. The system then starts the execution of the query using the resources. |
