By using MLM it is possible to get larger devices (even up to wafer size) or larger number of dies and wafers up to few batches typically. MLM is a smooth continuation from MPW production volumes upwards and therefore this may support also small/mid size volume production. Not all foundries support MLM arrangements.

Substrate mapping (or wafer mapping) is a process in which the performance of semiconductor devices on a substrate is represented by a map showing the performance as a colour-coded grid. The map is a convenient representation of the variation in performance across the substrate, since the distribution of those variations may be a clue as to ...
The equivalent for 300mm wafers is the FOUP (Front Opening Unified Pod). The greater flexibility of 300mm wafers means that it is not feasible to use SMIF technology and designs for 300mm, hence the reason for the emergence of FOUPs. Several FOUP SEMI standards, including SEMI E47.1-1106, [2] are related to both 300 and 450 mm wafers.
High purity silicon in different grades of purity is used for growing silicon ingots, which are sliced to wafers in a process called wafering. Compositionally pure polycrystalline silicon wafers are useful for photovoltaics. Dislocation-free and extremely flat single-crystal silicon wafers are required in the manufacture of computer chips.
[2] [3] Although the Bremner Wafer wasn't invented until 1902, David Bremner's company was modestly successful prior to its invention. When his sons took over the business circa 1905 they developed the Bremner Wafer. [2] The company remained in Chicago until 1984, when they moved to Denver, where it remains today. [4]
Multi-level marketing (MLM), also called network marketing [1] or pyramid selling, [2] [3] [4] is a controversial [4] and sometimes illegal marketing strategy for the sale of products or services in which the revenue of the MLM company is derived from a non-salaried workforce selling the company's products or services, while the earnings of the participants are derived from a pyramid-shaped or ...
