Channel Constrained Metalization (CCM), which employs photoresist patterning to confine electroless metal deposition to selected regions, is an inexpensive alternative to metal sputtering or evaporation. Using CCM we deposited arrays of square nickel electrodes up to one micron in thickness and between 11 um and 44 jxm on the side. Gaps between the electrodes ranging from 1 um to 4 pm were succ...

Electroless composite coatings used for achieving of high hardness, lubrication properties, non-stick surface, abrasive coating applications that by impregnation of soft and hard particles into Ni matrix. Electroless Nickel-phosphorous coatings properties and performance is greatly affected by the amount of phosphorus in them. The phosphor in this coating usually varies from 1 to 13 percent. In...

Due to the high hardness and wear resistance, electroless nickel-boron (Ni-B) coatings have found numerous applications. In the present study, the influence of the heating rate on the morphological features of oxidized electroless Ni-B coatings was investigated. The oxidation behavior of electroless coating layers was studied with TGA method under non-isothermal conditions at heating rates 5, 9...

We have analyzed the effects of immersion gold (i-Au) and electroless nickel (e-Ni) thickness, on the reliability of a semiconductor device which has special constraints on the absolute Ni and Au layer thickness. The electrochemical reactions involved in the deposition of immersion Au over Ni involves a substitution process by which Ni atoms are replaced by Au atoms. We demonstrate that in some...
