Figure 27.29 illustrates an example of how the filled structure forms with successive steps for a noncap-plated fill process. Note in this example how the surface button plating is mostly removed at the planarization step. Process development should be performed to target the optimum plating build-up method in regard to the process control of available planarization equipment.This means that whatever plating method is employed, both the deposit thickness across the panel and the net removal of deposit thickness as a result of planarization must be... 

Besides this one-time lamination method, there is a build-up method of lamination. 

With each of these build up methods, the desired layers of different materials are appKed. The choice of appbcation method depends mainly on the compound and the requirements for cover homogeneity. The hand build method, as an example, is the most sophisticated and most expensive build method. For these reasons it is only used for applications with extremely high demands on surface quality such as sizing or coating. 

This review is intended to highlight any new reaction types that have been discovered, novel structural features that have been encountered, and chemical patterns and principles that have been observed for this class of compounds. Due to space limitations, only very selective examples of reactions are presented. Heterobimetallic species have been prepared and characterized for most combinations of iron and other transition metals. Their potential in the cooperative activation of small molecules, such as CO and unsaturated hydrocarbons, is an important research focus for this class of compounds. For mixed-metal clusters, enormous efforts have been made to develop rational cluster build-up methods and their potential applications in catalysis. Some important reviews that are pertinent to this type of species have appeared in the literature. 

These two methods are closely related but differ in the point of initial attachment of the substituent from which the carbocyclic indole ring is constructed. One strategy for building up 2-substituted pyrroles capable of... 

It follows therefore that the specific surface of a mesoporous solid can be determined by the BET method (or from Point B) in just the same way as that of a non-porous solid. It is interesting, though not really surprising, that monolayer formation occurs by the same mechanism whether the surface is wholly external (Type II isotherm) or is largely located on the walls of mesopores (Type IV isotherm). Since the adsorption field falls off fairly rapidly with distance from the surface, the building up of the monolayer should not be affected by the presence of a neighbouring surface which, as in a mesopore, is situated at a distance large compared with the size of a molecule. 

IPP react with each other, releasiag pyrophosphate to form another allyl pyrophosphate containing 10 carbon atoms. The chain can successively build up by five-carbon units to yield polyisoprenes by head-to-tad condensations alternatively, tad-to-tad condensations of two units can yield squalene, a precursor of sterols. Similar condensation of two C2Q units yields phytoene, a precursor of carotenoids. This information is expected to help ia the development of genetic methods to control the hydrocarbon stmctures and yields. 

Tests Simulating Use Conditions. Several simulation tests involving wear and use testing have been developed. The first and only one to be adopted as a standard in the United States is AATCC Test Method 134-1975 for measuring the electrostatic propensity of carpets (60). In this test a person wearing standard neoprene and leather sole shoes and carrying a probe connected to an electrometer walks on a carpet for 30 to 60 s until the measured body voltage builds up to a maximum.
