摘要:
An integrated circuit having post passivation interconnections with a second connection pattern is disclosed. A passivation layer (preferably made of a non-oxide material) is formed over the integrated circuit already having a first plurality of contact pads in a first connection pattern. A buffer layer is then formed over the passivation layer. The buffer layer preferably is a silicon oxide layer with a thickness substantially smaller than a thickness of the passivation layer. A post passivation metal layer is deposited over the buffer layer. A second plurality of contact pads as part of the second connection pattern is formed in the post passivation metal layer.

A multi-lamp backlight system is disclosed. The multi-lamp backlight system includes a plurality of lamps, an inverter circuit and a current balance circuit. The inverter circuit is capable of converting a DC input signal to a pair of AC output signals, which have a 180 degree phase shift. The pair of AC output signals are delivered to the plurality of lamps. The current balance circuit is connected to the low voltage sides of the plurality of lamps for balancing the lamp currents.
摘要:
A system and method for detecting chamber leakage by measuring the reflectivity of an oxidized thin film. In a preferred embodiment, a method of detecting leaks in a chamber includes providing a first monitor workpiece, placing the first monitor workpiece in the chamber, and forming at least one film on the first monitor workpiece. The reflectivity of the least one film of the first monitor workpiece is measured, wherein the reflectivity indicates whether there are leaks in the at least one seal of the chamber. In another embodiment, the method includes providing a second monitor workpiece, placing the second monitor workpiece in the chamber, and forming at least one film on the second monitor workpiece. The reflectivity of the at least one film of the second monitor workpiece is measured, and the second monitor workpiece film reflectivity is compared to the first monitor workpiece film reflectivity.

A method of forming post passivation interconnects for an integrated circuit is disclosed. A passivation layer of a non-oxide material is formed over the integrated circuit. A buffer layer is then formed over the passivation layer. The buffer layer preferably is a silicon oxide layer with a thickness substantially smaller than a thickness of the passivation layer. A post passivation metal layer is deposited over the buffer layer and a connection pattern is formed in the post passivation metal layer.
