Consumables suppliers

The differences and similarities in the requirements of CMP for microelectronics manufacturing and microfabrication are summarized in Table 14.1. This comparison gives an overview of the parameters relevant to CMP and is intended to serve as a guideline for CMP practitioners, consumable suppliers, equipment manufacturers, and others. Polishing tools and consumable sets capable of handling MEMS-specific tasks will be discussed at the end of this section. The following is a list of these terms for comparison. 

In most cases, the process engineers had to use the standard slurries and pads of More Moore developments. That was true until recently, when the consumables suppliers discovered the potential of the enormously growing MEMS market. Today, slurries optimized for MEMS processes are available. Slurry companies had to react on the demands of the integrated device manufacturers and foundries and learned to formulate tunable polishing slurries. By using sophisticated additives, slurries fulfilling the requirements for power device fabrication and MEMS manufacturing have been developed. 

The forays into the potential optical printing market became known throughout the imaging community, and several applications appeared. The Litton Advanced Data System, located in Beverly Hill, CA, had contracts to develop electronically generated tickets for entertainment events as well as for transportation purposes. Some collaboration to develop tickets in which graphics could be pre-printed via contact exposures, with variable information to be printed from electronically generated sources was undertaken. Litton looked to DuPont for support, but it was decided that DuPont lacked the resources to do so. Inherently, DuPont looked at itself as a consumable supplier, rather than a system operator. This inevitably resulted in potential customers seeking other materials to solve their problems. 

A recent reference [1] lists twenty suppliers of structural acrylic adhesives. Many other companies have been involved in this area, and it is often felt that acrylic adhesives have unrealized technical potential [2]. Acrylic adhesives are not commonly found in the consumer market, but fill an important niche there in the bonding of rear view mirrors to windshields in automobiles. 

The drive for these additional requirements has come not from the suppliers but from users, such as the automotive, utilities, telecommunications, software, and aerospace industries which purchase millions of products and services used to produce the goods and services they provide to the consumer. Rather than invoke customer-specific conditions in each contract, the larger purchasers perceive real benefits from agreeing common quality system requirements for their industry sector. Quite often a supplier will be supplying more than one customer in a particular sector and hence costs increase for both the supplier and the customer if the supplier has to meet different requirements that serve the same objective. All customers desire products and services that consistently/ meet their requirements. While the physical and functional requirements for the product or service will differ, the requirements governing the manner in which their quality is to be achieved, controlled, and assured need not differ. Differences in quality system requirements may arise between industry sectors where the technology, complexity, and risks are different. 

Preserving product while the product is under your control may be addressed by your handling and packaging provisions, but in-process preservation may also be necessary to protect finishes from deterioration during further processing. Such measures need to be specified in the work instructions for particular products. For products that start to deteriorate when the packaging seal is broken, the supplier s responsibility extends beyond delivery to the point of use. In such cases markings need to be applied to the containers to warn the consumers of the risks. 

The third transition procedure defines the rules under which competitive suppliers of electricity can compete for end users. There are two polar models that are often debated for power market organization the direct access (or bilateral contracts) regime, and the Poolco regime. Under direct access, consumers enter into direct contracts with competitive suppliers of electricity, and competitive providers of electricity enter into contracts with, and pay an access fee to, the local (regulated) distribution company for the use of local power lines. 

Consumer installations which supply LPG to more than one user (e.g. metered estates, holiday home parks, caravan sites) require the gas supplier (i.e. the site owner/operator, not the LPG supplier) to obtain prior consent from the Office of Gas Supply (Ofgas) and, for the necessary pipework installation, from the Department of Energy, Pipelines Inspectorate. 

There is a constant effort by both the supplier and consumer of lubricants to reduce the number of grades in use. The various lubricant requirements of plant not only limit the extent of this rationalization but also create the continuing need for a large number of grades with different characteristics. 

Section 6 of the Act has been amended by the Consumer Protection Act 1987 and now imposes specific duties on manufacturers, importers, designers and suppliers to ensure that articles and substance supplied for use at work are safe and without risk to health. 

We can expect drastic changes in the food packaging industry. Some will arise from new consumer needs, new or expanded food supplies and products, and new food preservation systems such as aseptic packaging. Others will result from societally based constraints such as safety in health and hazardous use (as in the child safety closure legislation) and consumer protection against fraud, misinformation, or wrongful use where the burden for awareness is no longer on the buyer but on the supplier. Other such constraints will arise from environmental concerns or material scarcities. 

Ericsson is the world s leading supplier of telecommunications with the largest customer base, including the world s top ten operators. Four out of every ten mobile calls are handled by Ericsson equipment. The company has been in business since 1876 and now operates in more than 140 countries, employing 100,000 people. Ericsson is split into five business divisions one of these is known as the Consumer Products Division and presents the focus of this case study. 

Ensure that the actual instrument configuration conforms to what is written under Experimental supplier, models, modifications, consumables (HPLC or GC columns, gaskets, etc.), and software for the main instrument, peripherals (injectors, integrators, computers, printers, plotters, etc.), and ancillary equipment (vortexer, dispensers, balances, centrifuges, filters, tubing, etc.). 

When the users are not the developers, a major mismatch can result between the material design and the end use. Thus, the developer will have extensive product application development to do, which is both expensive and time-consuming. Initial market potentials can be small, and manufacturing capital costs can be high. Thus, the development of new performance materials as the foundation of a materials business does not look very attractive to materials suppliers. Yet, these enabling technologies are very important to the future development of many basic industries. Some models for the successful development of advanced-performance materials are the following ... 

A Danish charcuterie company increased its sales of salami by 50% by being on the list of suppliers to a pizza chain that sells organic pizzas to British consumers (Organic Denmark, 2003). 

Over a long time period it may well not be possible to duplicate library cell culture conditions. What happens when the lot of media used in the final culture step prior to pyrolysis has been consumed Can culture media suppliers assure nutritional identity between batches Media types for growth of fastidious strains invariably include natural products such as brewer s yeast, tryptic soy, serum, egg, chocolate, and/or sheep blood. Trace components in natural products cannot be controlled to assure an infinite, invariable supply. The microtiter plate wells used here do not hold much media. Even so, the day will come when all media supplies are consumed and a change in batch is unavoidable. When that happens, if there were no effective way to compensate spectra for the resulting distortions, it would be necessary to re-culture and re-analyze replicates for every strain in the reference library. Until recently the potential for obsolescence was a major disincentive for developing PyMS spectral libraries of bacteria. Why this is no longer an insurmountable problem is discussed in the next section. 

An enterprise can define its own standards, which it enforces by requesting suppliers and, in some cases, retailers to follow specific guidelines in order to be considered for contracts, and by merging the brand image with the image of the quality standards in marketing to consumers. This... 

Chemicals and consumables normally arrive from the supplier in a suitable container, appropriately labelled. The information given on the packaging is the responsibility of the supplier and is legally required to conform to minimum requirements under packaging and labelling regulations. Typically, the label on a container for a commercially sold chemical will indicate the following ... 

Industry too has contributed toward the establishment of an international consensus. According to Mardsen and Arce (1995,1274) the retail and corporate sector is often the forerunner in the regulation of food safety and quality. In this way, public opinion and consumer choice give large retailers great power in setting standards for their suppliers (Murdock, Marsden Banks, 2000, p. 109).
