20120064714 | CONTACT FORMATION METHOD INCORPORATING A PREVENTATIVE ETCH STEP FOR REDUCING INTERLAYER DIELECTRIC MATERIAL FLAKE DEFECTS - Disclosed are embodiments of a contact formation technique that incorporates a preventative etch step to reduce interlayer dielectric material flaking (e.g., borophosphosilicate glass (BPSG) flaking) and, thereby to reduce surface defects. Specifically, contact openings, which extend through a dielectric layer to semiconductor devices in and/or on a center portion of a substrate, can be filled with a conductor layer deposited by chemical vapor deposition (CVD). Chemical mechanical polishing (CMP) of the conductor layer can be performed to complete the contact structures. However, before the CMP process is performed (e.g., either before the contact openings are ever formed or before the contact openings are filled), a preventative etch process can be performed to remove any dielectric material from above the edge portion of the substrate. Removing the dielectric material from above the edge portion of the substrate prior to CMP reduces the occurrence of surface defects caused by dielectric material flaking. | 03-15-2012 |

20150127761 | APPARATUS AND METHOD FOR CLIENT-SIDE FLOW CONTROL IN A REMOTE ACCESS ENVIRONMENT - A client-side flow control mechanism for controlling the flow of messages communicated from a service to a client in a remote access system. The service, which may be a managed or unmanaged service, may communicate messages to the client where the messages include a service sequence ID (SSI). As the client processes the messages from the service, the client responds with a client sequence ID (CSI). The SSI and CSI values determine the number of messages that are in transmission queues. The service compares a difference between the current SSI and CSI to a stop window value. If the difference is greater than the stop window value, transmission of messages from the service to the client is turned OFF. The client continues to send CSI acknowledgments as it processes messages. Once the difference falls below a start window value, the transmission of messages to the client is turned ON. | 05-07-2015 |
