摘要:
A bonding structure with a buffer layer, and a method of forming the same are provided. The bonding structure comprises a first substrate with metal pads thereon, a protection layer covered on the surface of the substrate, a first adhesive metal layer formed on the metal pads, a buffer layer coated on the protection layer and the metal pads, a first metal layer covered on the buffer layer, and a second substrate with electrodes and a bonding layer thereon. The first metal layer, the electrodes and the bonding layer are bonded to form the bonding structure. Direct bonding can be performed through surface activation or heat pressure. The method uses fewer steps and is more reliable. The temperature required for bonding the structure is lower. The bonding density between the contacted surfaces is increased to a fine pitch. The quality at the bonding points is increased because fewer contaminations between the contacted surfaces are generated.

A wafer level chip scale packaging structure and the method of fabricating the same are disclosed to form a sacrificial layer below the bump using a normal semiconductor process. The bump is used to connect the signals between the Si wafer and the PCB. The interface between the sacrificial layer and the PCB is the weakest part in the whole structure. When the stress applied to the bump is overloaded, the interface between the sacrificial layer and the PCB will crash to remove the stress generated by different thermal expansion coefficients of the Si wafer and the PCB. The sacrificial layer would help avoid the crash occurring to the bump to protect the electrical conduction between the Si wafer and the PCB.

A leak detection system (50) including a flow accelerator for directing and accelerating leaking gas toward a sampling probe (70). A probe input tube (72) is inserted into one end (62B) of a larger diameter adapter tube (60) to position the end of the tube (72) past a suction opening (62D). The other end (62A) of the adapter tube is positioned to receive leaking gas. A suction is applied to the suction opening, which tends to draw the leaking gas into the adapter tube end (62A). Some of the leaking gas is drawn into the suction opening, and some into the end of the sampling tube. The suction causes the leaking gas to be accelerated toward the sampling probe input port. The suction can be created by a venturi (66C) through which is passed a gas under pressure. The acceleration of the gas through the venturi creates the suction. The flow accelerator significantly reduces the time required to locate small gas leaks.
