Portable electronic products have been extended for high performance and high-density silicon node applications in recent years. In order to meet customer increased expectations regarding functionality, size, power dissipation, thermal performance and cost. This requires more robust and more reliable WLP solution, where Fan-Out Wafer Level Package will play an emphasized role in terms of system integration,...
Wafer Level Packaging (WLP) is a packaging technology focusing on integrated circuit (IC) packaging at wafer level instead of die level. WLP essentially consists of IC foundry fabrication process and subsequent device interconnection and back-end passivation process. The general wafer level packages (WLPs) are designed for fan-in chip scale packaging but the shrinkage of pad pitch and size at the...
Wafer-Level Packaging (WLP) has emerged in modern years and played a prominent role in both semiconductor and Integrated Circuit (IC) field, as well as in Micro-ElectroMechanical Systems (MEMS) applications and fields for their distinguishing operating mechanism and adaptive design variety. In this study, numerous kinds of mature packaging technologies combined with innovation as well as integration...
Wafer Level Packaging (WLP), a new packaging technology which is dedicated to integrated circuit (IC) packaging at wafer level to replace die level packaging. WLP basically includes front-end IC foundry process and back-end device packaging process. The major benefits of WLP contain manufacture period shortening, product size reduction, and production cost down, all have been aligned with the latest...
Wafer Level Packaging (WLP) has started to shine and played a prominent role in recent years in both semiconductor and Integrated Circuit (IC) field, especially in now thriving Micro-Electro-Mechanical System (MEMS) applications on account of its distinctive operating mechanism and adaptive design variety. In this study, several crucial WLP technologies are disclosed in detail, including Wafer to...
Wafer Level Packaging (WLP) has started to thrive in recent years in IC packaging domain, especially in Micro-Electro-Mechanical Systems (MEMS) field due to its unique operating characteristic and design diversity. In this paper, several significant WLP technologies, including wafer to wafer (W2W) bonding, wafer level wire bonding, wafer level compound molding, and compound lapping, are disclosed...
The wafer level hermetic packaging is a method of sealing micro-devices containing movable parts with a capping wafer in vacuum. The capping wafer is etched to form a cavity which will cover over the MEMS devices and the process is carried out at the wafer level before the device wafer is diced. Glass frit bonding is described as the most leak proof and robust sealing mechanism of all available methods...
Circulating brain natriuretic peptide (BNP) has recently served as a marker of left ventricular dysfunction, while treadmill exercise has been used clinically for assessing cardiac problems. The current study was undertaken to investigate the possible effect of exercise on circulating BNP concentrations. A total of 138 blood samples from 23 healthy men aged 23 to 27 years (mean, 25) was analyzed....
