Abstract Bioelectronic medicine treats chronic diseases by sensing, processing, and modulating the electronic signals produced in nervous system of human body, labeled ‘neural signals’. While circuits have been used for several years this domain, progress microelectronic technology is now allowing increasingly accurate targeted solutions therapeutic benefits. For example, it becoming possible t...
the purpose of the present study was to see which one of the two instruction-processing instruction (pi) and meaningful output based instruction (mobi) accompanied with prompt and recast- is more effective on efl learners’ writing accuracy. in order to homogenize the participants in term of language proficiency a preliminary english test (pet) was administrated between 74 intermediate students ...
-A new inverse analysis method is presented to identify parameters of heat convection in microelectronic packages. This approach adopts a modified Micro Genetic Algorithm (μGA) in finding the global optimum of parameters. A reduced-basis approach is introduced in the forward heat transfer analysis so as to significantly improve the efficiency in the calculation. Different identification procedu...
Many microelectronic chips contain embedded memory arrays. A single SRAM bit-cell contains several transistors. Failure of any of the transistors makes the entire bit-cell inoperable. Dual-beam Focused Ion Beam (FIB) combines the slicing capability of FIB with in-situ SEM imaging. The combination offers unparalleled precision in looking for root causes of failures in microelectronic devices. On...
Silicon photonics has generated an increasing interest in recent years mainly for optical communications optical interconnects in microelectronic circuits or bio-sensing applications. The development of elementary passive and active components (including detectors and modulators), which are mainly fabricated on the silicon on insulator platform for CMOS-compatible fabrication, has reached such ...
Synchrotron-based X-ray microbeam measurements were performed on silicon-on-insulator (SOI) features strained by adjacent shallow-trench-isolation (STI). Strain engineering in microelectronic technology represents an important aspect of the enhancement in complementary metal-oxide semiconductor (CMOS) device performance. Because of the complexity of the composite geometry associated with microe...
A literature review on the recent applications and developments of thermosiphon loop is conducted. In particular, systems suitable for cooling of microelectronic chips are reviewed in greater detail. The advantages of using a thermosiphon loop in microelectronic applications are discussed. The instability and temperature overshoot at the start-up have been identified as major problems which req...
An analytically ANALYTICAL MODEL FOR SIMULATING THE THERMAL BEHAVIOR OF MICROELECTRONIC SYSTEMS P. Teertstra, J.R. Culham and M.M. Yovanovich Microelectronics Heat Transfer Laboratory Department of Mechanical Engineering University of Waterloo Waterloo, Ontario, Canada N2L 3G1
Fuzzy controllers have been proven to be universal, that is, they can provide any control surface [1]. Their microelectronic implementation is very suitable to achieve high-speed (real-time operation), and low area and power consumption. This paper focuses on discussing the two basic approaches that can be employed to design programmable universal controller integrated circuits. Analog, mixed-s...
A single-mask process is used to fabricate metal microchannels of 5–10 μm in width, 10–40 μm in height and millimeters in length, monolithically (i.e., no bonding) on the chip front side. Taking advantage of the small size and the diverging cross-section allowed for these microchannels, we explore the air cooling of a microelectronic chip, addressing the limitations of the liquid cooling with t...
