Device Fabrication and Characterization

The development of new polyanhydrides has sparked researchers to developed new device fabrication and characterization techniques, instrumentation, and experimental and mathematical models that can be extended to the study of other systems. The growing interest in developing new chemistries and drug release systems based on polyanhydrides promises a rich harvest of new applications and drug release technologies, as well as new characterization techniques that can be extended to other materials. Future endeavors will likely focus on multicomponent polyanhydride systems, combining new chemical functionalities to tailor polyanhydrides for specific applications.

The fabrication and characterization of a fiber optic pH sensor based on evanescent wave absorption was presented by Lee63. The unclad portion of a multi-mode optical fibre was coated with the sol-gel doped with pH sensitive dye. The sensitivity of the device increased when the multiple sol-gel coatings were used in the sensing region. The dynamic range and the temporal response of the sensor were investigated for two different dyes -bromocresol purple and bromocresol green.

Recently, efforts have been devoted to the fabrication and characterization of PbZri- Ti c03 family thin films for their potential applications in nonvolatile memory devices (See Ref. 17, for example). Partly because of the convenient stoichiometry control during processing, it was found that chemical methods, such as sol-gel and metal organic decomposition (MOD), are superior to physical means in many aspects. To appreciate better the science and technology of ferroelectric thin-film fabrication, it is important to give a brief account of the past efforts and the present status and, it is hoped, shed some light on the future.

In this chapter, we will describe and discuss the fabrication and characterization of metal oxide thick- and thin-film sensors (which are based on the conductivity modulation principle) and SAW devices (which are based on frequency modulation). The sensing properties of thick or thin semiconductor films with various components will be discussed, focusing on sensitivity and stability. In addition, SAW-type CWA sensors will be introduced for different pairs of inteidigitated transducer (IDT) fingers, various wave lengths, and different polymer coatings on the input and output IDTs of the device.

On another front, to accomplish electrical measurments of individual NWs, free of parasitic effects, and to develop competitive sensors, various fabrication and characterization strategies have been evaluated. For instance, low-current measur ent protocols have been found to aUow the devices to operate long-term withont degradation of their performance (Hemandez-Ramirez et al. 2007a, b). Thus the present state of development of NW-based technologies has led to complete and weh-controUed characterization of proof-of-concept devices, which were previously imattainable (Comini et al. 2009). 

In the following, the fabrication and characterization of micromachined high frequency focused polymer ultrasonic transducers in a manner that is compatible with CMOS microelectronics, and MEMS batch fabrication techniques, are described. The specifics of the electronics are not described here, but the interested reader may find more details elsewhere [75, 76, 81-84]. The transducer is capable of being manufactured on silicon wafers after the completion of CMOS electronics. These two key elements enable the eventual creation of a monolithic transducer chip that does not require modification of the standard circuit fabrication process. This type of transducer chip will likely follow the path of other MEMS devices such as accelerometers, gene chips and digital micromirror arrays, where batch production, high yields and... 

The first experimental works dedicated to the fabrication and characterization of Auger-suppressed extraction photodetectors handled mostly homojunction devices. Ashley et al. [363] fabricated three-layer p im structures in Inj-xAlxSb. They utilized molecular beam (MBE) and (lOO)-oriented InSb substrate. The doping level of the % zone was about 10 cm , its thickness 0.75-3 pm. The dopant concentrations in highly doped zones were higher than 10 cm . Etching was used to fabricate mesa stmctures with an area of about 10 " cm and passivation with anodic oxide was used.
