20160050134 | METHOD FOR SETTING HEARTBEAT TIMER, TERMINAL AND SERVER - The present invention provides a method for setting a heartbeat timer, a terminal and a server. The method includes: a terminal installed with an application receives a timer setting request carrying first setting information of a to-be-set timer transmitted by the application; the terminal transmits a timer query request to a server according to the first setting information; the timer query request carries a query identifier generated according to the first setting information; the terminal receives a timer query response returned by the server, where the timer query response carries a query result indicating whether a heartbeat timer list includes a heartbeat timer information entry matched with the query identifier; the terminal determines whether to set the to-be-set timer for the application according to the query result, and performs a corresponding setting operation. The solution can effectively manage and set a heartbeat timer within a mobile phone terminal. | 02-18-2016 |

20150187794 | METHOD FOR FORMING DEEP TRENCH ISOLATION FOR RF DEVICES ON SOI - A semiconductor device includes a silicon-on-insulator (SOI) substrate having a stack of a first semiconductor substrate, a buried insulating layer and a second semiconductor substrate formed in a first region and a deep trench isolation disposed in a second region. The method of forming the semiconductor device includes providing a SOI substrate having shallow trench isolations (STIs) and transistors formed within and on the second semiconductor substrate, respectively. The method also includes forming a hard mask over the first region and removing the STIs, the transistors, the second semiconductor substrate and the buried insulating layer in the second region using the hard mask as a mask, and forming a capping layer covering the deep trench isolation and the second semiconductor substrate including the transistors. | 07-02-2015 |
20160090292 | METHOD TO IMPROVE CANTILEVER PROCESS PERFORMANCE - A method of manufacturing a cantilever structure includes providing a semiconductor substrate, forming a recess in the semiconductor substrate, forming a sacrificial layer in the recess, forming a cantilever structure layer on the semiconductor substrate and the sacrificial layer, performing an etching process to remove a portion of the cantilever structure layer until a surface of the sacrificial layer is exposed to form a cantilever structure and an opening, and removing a portion of the sacrificial layer to form a void below the cantilever structure so that the cantilever structure is suspended in the void. The cantilever structure thus formed has good morphological properties to ensure that the cantilever structure is free of residues at the bottom and has excellent suspension even if the width of the cantilever structure is relatively large. | 03-31-2016 |
