Abstract: An approach for reducing backend system calls. The approach determines if a client request, comprising a backend system call, has timed out. If the client request has timed out, then the approach generates a unique identity associated with the client request. The approach creates a fault message indicating a timeout of the client request. The approach inserts the unique identity into the fault message. The approach sends the fault message to the client as a response to the request. The approach creates a data structure comprising the unique identity, a timeout value, and a message buffer. The approach inserts the data structure into a message queue. Subsequently, a client sending a next request containing the unique identity can receive a response, from a slow responding backend server, after the timeout of the previous request without incurring the expense and overhead of another backend system call.

Abstract: Detecting non-callable external component APIs is provided. It is determined whether a first function call stack of a worker thread in a multi-threaded application of the computer matches a second function call stack of the worker thread. In response to determining that the first function call stack matches the second function call stack of the worker thread, an external component application programming interface (API) corresponding to the worker thread is identified from a function call stack of the worker thread. The external component API corresponding to the worker thread is marked as non-callable in an API state map. The worker thread is marked as being in a hang state. The worker thread in the hang state is terminated as a remediation action step to maintain performance.

Abstract: A call for communication is detected between applications, where the call requires input from a plurality of threads of the applications via editing of a single control message in a queue such that the single control message reflects data from each of the applications. An attempt by a first of the plurality of threads to edit the single control message is detected while a second of the plurality of threads is editing the single control message. A message is sent to the first of the plurality of threads that details a status of the single control message in response to detecting the attempt. The call for communication is responded to using the single control message in response to detecting that each of the plurality of threads has edited the single control message.

Abstract: A process for forming a semiconductor wafer which is single side polished improves nanotopography and flatness of the polished wafer. The process reduces the effect of back side surface features, such as edge ring phenomena and back side laser marks, on nanotopography and local site flatness, thereby improving oxide layer uniformity for chemical/mechanical planarization (CMP) processing, and flatness on the polished front side of the wafer after polishing. The wafer is mounted on a polishing block by wax so as to minimize transfer of imperfections in the wax to the front side of the wafer. In particular, the wafer is retained in a centered position on the polishing block. Moreover, the wafer is mounted at atmospheric pressure while still removing air bubbles from the wax.

Abstract: A process for forming a semiconductor wafer which is single side polished improves nanotopology and flatness of the polished wafer. The process reduces the effect of back side surface features, such as edge ring phenomena and back side laser marks, on nanotopology, thereby improving oxide layer uniformity for chemical/mechanical planarization (CMP) processing, and flatness on the polished front side of the wafer after polishing. The wafer is mounted on a polishing block by wax. The edge ring causes certain deformation and stress in the wafer upon mounting, which is held by the wax. After mounting, the wax is heated to allow the wafer to relax, removing the stress, without degrading the bond of the wafer to the polishing block. The wafer is polished and removed from the polishing blocks. The polished surface substantially retains its shape after being de-mounted from the block.
