8.3.6 Deep silicon etching

MEMS structures often require etching to a much greater depth than is needed for microelectronics. A rate of 1–2 μm min−1 may be quite sufficient for making transistors less than 1 mm deep, but to etch through 600 mm of silicon to form an accelerometer would take all day. The advent of MEMS and wafer-level packaging applications, therefore, brought a need for yet faster anisotropic etches, requiring advances both in the process and in the etching equipment.

7 Unofficial work cultures
In this unit, we are going to look at a number of situations which put a strain on the idea that caring is just 'being ordinary', including times when people are giving intimate care. In these special circumstances, since the normal rules do not apply, we have to develop a set of special rules to guide practice.

MAS.962 Special Topics in Media Technology: Computational Semantics (MIT)
How do words get their meanings? How can word meanings be represented and used by machines? We will explore three families of approaches to these questions from a computational perspective. Relational / structural methods such as semantic networks represent the meaning of words in terms of their relations to other words. Knowledge of the world through perception and action leads to the notion of external grounding, a process by which word meanings are 'attached' to the world. How an agent theori

1.2 The economics of water

Water has traditionally been regarded as a free resource in the sense that there is nothing to stop anybody collecting their own supply of water from rainfall. Even water from the public supply is very cheap. Although sand and gravel only cost around £12 a tonne in the UK in 2004 (Argles, 2005), the average of £0.80 per tonne (a cubic metre) for supply of mains water in England and Wales is even cheaper. However, some regions of the world are less fortunate. For example, in Kuwait most fres
