摘要:
An apparatus for dispensing fusible material onto a surface, wherein the fusible material is in molten form, is provided. The apparatus comprises a dispensing assembly comprising a seal structure. The seal structure controls dispensing of the fusible material. One or more gas injectors are coupled to the dispensing assembly. Each of the one or more gas injectors is adapted to inject at least one gas to the dispensing assembly for controlling a gas environment surrounding at least a portion of the seal structure. An oxidation rate of the fusible material is controlled as a function of at least one characteristic of the at least one gas.

A method of forming a multichip module in which a thin film structure is formed on a temporary carrier and then an electrically insulating frame is attached to the thin film structure. A semiconductor device is attached to the thin film structure and then the temporary carrier is removed. Lastly, at least one semiconductor device is attached to the other side of the thin film structure. There is interconnectvity through the thin film structure between the semiconductor devices and the frame.

摘要:
A fixture having a bottom plate, top plate and an expansion block interposed between the bottom plate and top plate. A workpiece is positioned between the expansion block and bottom plate. When the fixture is heated, there is a net displacement exerted by the expansion block so as to apply pressure to the workpiece. The pressure applied by the fixture to the workpiece is due solely to the thermal expansion of the fixture when it is heated.
