Device Test Once the Front End Process has been completed, the semiconductor devices are subjected to a variety of electrical tests to determine if they function properly. The proportion of devices on the wafer found to perform properly is referred to as the yield. The fab tests the chips on...
The invention provides a front-end manufacturing process of a semiconductor device, comprising the following steps: cleaning and dehydrating the surface of a silicon chip; forming a protective layer on the back side of the silicon chip; forming a device at the front side of the silicon chip; ...
Front end semiconductor manufacturing refers to fabrication from a blank wafer to a completed wafer that has not yet been separated into individual chips.
Semiconductordevices are completed through the front-end process (wafer processing operation) and the back-end process (assembly process) described below. (In the following description of the element process, a very small area of awafersurface is magnified and shown schematically.) ...

Back-end process, which is the last step of manufacturing of semiconductors, indicates a series of processes that inspects wafers produced from front-end fabrication facilities and produces finished products by assembling those wafers. <SK Hynix’s semiconductor back-end process production facility in...
With high performance of semiconductors, testing in production processes is becoming more important than ever. In the front-end process where circuits are formed on wafers, testing is performed to check if each process has been performed properly and to assure the quality of manufactured chips. TEL...
Compared with the front-end process of designing and fabricating wafers, the back-end process of packaging has been undervalued for two reasons: First, it’s still possible to package wafers using old-generation equipment. Second, packaging is mostly done by outsourced semiconductor assembl...

The wafer support system (WSS) process requires a carrier that can support a thin wafer and a temporary bonding adhesive (TBA). After debonding the carrier, mounting tape is also required to firmly attach the thin wafer that formed bumps on its front and back to a ring frame. ...
