Patent DE-3789172-D1 (DE)

Abstract: A process for bonding silicon die (10) to a package. This process comprises the following steps: (a) providing to the back surface of the die (12) an adhesion layer (14) of material which exhibits superior adhesion to both the silicon die and a subsequently applied barrier layer (16); (b) providing to the adhesion layer (14) a barrier layer (16) which is impervious to silicon; (c) providing to the barrier layer (16) a bonding layer (18); and (d) bonding the die to the package by activating a binder composition disposed at the interface of the package and the bonding layer. The barrier layer prevents the migration of silicon to the bonding layer, both at the time of application of the bonding layer to the die and at the time of bonding the die to the package. The adhesion layer enhances the adhesion of the barrier layer material to the back surface of the die. Titanium is the preferred adhesion layer material while tungsten is the preferred barrier layer material. The bonding layer preferably comprises gold while the preferred binder composition is a gold-tin alloy solder. The enhanced adhesion of the barrier layer which prevents silicon migration into the gold produces highly reliable bonds. In another embodiment, a stress relief layer is interposed between the adhesion layer and the back of the silicon die. The material of the stress relief layer is alloyed to the silicon at the back surface of the die which relieves stresses in the die and enhances the planarity of the back surface. This produces bonds which exhibit superior electrical and thermal contact characteristics.

Abstract: Conductive polymer compositions comprising a matrix polymer and a conductive particulate filler dispersed in the matrix polymer. At least some of the filler particles comprise a polymer and a homogeneous filler, eg. carbon black, dispersed therein. Preferably the filler is highly cross-linked so that it has a hot modulus of at least 250 psi (l7.5 kg/cm<2>) and is then dispersed in a melt-shapeable polymer. In this way it is possible to make conductive polymer compositions of high resistivity, eg. at least l,000 ohm-cm, with a high degree of reproduceability. Alternatively, the matrix polymer has a hot modulus of at least 250 psi (l7.5 kg/cm<2>) and is sintered.

Abstract: A method of making a papermarker's felt which includes the steps of forming a pin seam fabric (1) having interdigitated loops (4) at the ends of the fabric joined by a pin (5). A batt of fibrous material (6) is needled into at least one face of the fabric (1) and across the pin seam joint. When the felt is to be installed on the papermaking machine, the pin (5) is removed and the felt is bent back on itself at the joint to bring the portions of the batt (6) adjacent the joint into contiguous or contacting relation and cause the loops (4) to separate. The batt (6) is then cut along a line extending through the separated loops (4) to provide a flat or opened felt which can then be installed on the papermaking machine. After installation, the loops (4) are interdigitated and the pin (5) is reinserted through the loops (4) to provide the endless felt construction.
