Micro machining

The micro-machined silicon sensor is fabricated in three basic types of pressure sensors. The three types which are shown in Figure 6.10, are ... 

To realize micro reactors with sensing and surface-control structures, the underlying fabrication methods have to go beyond MEMS and classical micro machining [75]. Plastic and glass manufacture and also novel innovative methods such as soft lithography have to be developed further and applied. 

Central part of this reaction unit is a split-recombine chip micro mixer made of silicon based on a series of fork-like channel segments [32-36]. Standard silicon micro machining was applied to machine these segments into a silicon plate which was irreversibly joined to a silicon top plate by anodic bonding (Figure 4.16). 

For the most part, new materials suited for low cost mass production purposes and micro machining technologies are used to form three basic building blocks of every micro system ... 

Pricing as well as reliability considerations have led to an almost exclusive use of Si-based (i.e. Si and SOI) micro machined devices. Packaging and assembly has focused on ceramics (A1203, AIN, Low Temperature Co-fired Ceramics LTCC), Printed Circuit Board (PCB-) and Surface Mount Device (SMD-) technology and multichip modules (MCM s). 

Bulk and surface micro machining constitute the main 3D-semiconductor processes. Wet etchants such as KOH, EDP or TMAH or alternatively, a dry etching...

Communication with the simulation tool should be done by bit or word oriented shared memory areas. Complex technological systems for real operations consist of several physical components, controllers, sensors and actuators, which define their behaviour. Information runs between these parts via links with bar systems. Different types of sensors, actuators and other micro machines are available on the market - corresponding to real sensors like light bars, distance accelerators and other instruments. The positioning can be done graphically or textually (Figure 7). 

That fast screening does not necessarily mean parallel screening has been convincingly demonstrated by the group of de Bellefon [50]. They combined a micro-machined mixer tube reactor and applied pulsed injections of the respective cata-...

Version (b). This design of meander mixer was actually realized. It refers to a structure with a large number of mixing elements which was micro-machined by precision milling in a plastic material [47]. Irreversible sealing of the channel was accomplished by insertion of a thin PMMA foil via solvent bonding. 

The L-shaped structures can simply be made by conventional silicon micro machining. The microstructured wafer was covered by a glass slip using a thin layer of a silicone adhesive [153].
