Integrated circuits prototype

FPGA can be conceived as one application specific integrated circuit (ASIC) in a prototype stage. Two technologies have their own pros and cons, hence have their market share based on application. Major differences between ASIC and FPGA come from costs, tool availability, performance, and design flexibility. The major distinct features have been compared in Table APV/1.3-1.

We have developed two prototype integrated circuits for initial BBIC testing purposes. The first prototype was fabricated in a 1.2 pm CMOS process employing a... 

A list of the important points for innovations are (1) the progress of the scientific understanding of the science and physics of the liquid crystal of around 1960 (2) the development of integrated circuit according to Jack Kilby in 1959 (3) the discovery of the electro-optical effect in liquid crystals and the invention of the LCD by Williams in 1962 (4) the development of CMOS transistors by Frank Manon Wanlass in 1963 (5) the prototype presentation of the LCD by the research group of Heilmeier at RCA in 1968 (6) the synthesis of room temperature liquid crystal MBBA by Hans Kelker et al. in 1969 (7) the synthesis of the transparent ITO electrode by Yoshiyuki Katsube in 1969 (8) the proposal of a DSM theory by the Orsay LC group and finally, (9) the decision to start the development of a simple calculator instead of a TV set in 1969. 

This prototype employs a wireless communication module having a 32 bit microcomputer, 128 kbyte RAM, several serial communication ports, as well as an RFIC (Radio Frequency Integrated Circuit) based on IEEE802.15.4. 

Epoxy/Ni adhesives ean be used as integrated circuit (IC) packaging materials due to their lower cost than epoxy/Ag adhesives with acceptable electrical conductivity. In this work, conductive epoxy/Ni adhesives were prepared by solution method and filled into holes connecting the multilayers of a novel prototype designed to be used in electronic components in circuit boards, in order to study the geometrical effects on the prototype s electrical resistance. An empirical equation was obtained for the contact resistance (Rc) measured after cure. We also show that Ohm s law adequately describes the effects of the bulk adhesive resistance R on prototype s electrical resistance. 

Fabrication of the prototype is an important step in product development. It demonstrates that the various components can indeed be physically integrated to form the final product with the desired functionalities. Consider a UV sensor. While its functionality depends on the physical response of a certain nanomaterial in the presence of UV light, an electric circuit and a display system are required for a functional consumer product. The availability of a prototype is essential in test marketing, safety tests, reliability tests and so on. However, the development of consumer-oriented products often involves a considerable amount of trial-and-error, which can lead to costly delays in product launching [10]. 

A prototype battery of about 8 mm thickness and a total area of 1 cm2 had a rated capacity of 150 mAh over the full voltage range, which extends from 3.6 to 1.5 V. The battery design is suitable for circuit integration as a standby power source for low current electronic devices.

The CAREM reactor under development in Argentina is a 100 MW(th) (about 27 MW(e)) design based on natural circulation. It has an integrated primary circuit comprising the core, steam generators, control rods with their drive mechanisms and the entire primary coolant. Several experiments examining core neutronics and thermal hydraulics have been conducted in test facilities. The construction of a prototype is planned.
