Silicon Planar Technology And Technology

New sciences have also contributed to technology, as in the theoretical preparation for the invention of the steam engine. In the 20th century, innovations in semiconductor technology increased the performance and decreased the cost of electronic materials and devices by a factor of a million, an achievement unparalleled in the history of any technology.”

There has recently been a lot of interest in PDMS based microfluidic systems due the numerous advantages it offers compared to glass and silicon [Kong J et al, 2009; Tanyu Wang et al, 2013 and Alphonsus et al, 2010]. PDMS is easy to fabricate, flexible, optically transparent and can irreversibly bind to itself through the application of oxygen plasma. Another major advantage is that PDMS based devices can be fabricated in normal laboratory conditions as opposed to clean room conditions that are expensive to maintain and access. PDMS is also hydrophobic that is desirable for

The use of nano-materials and extreme precision micro-engineering has the potential for great improvement in the world of electronics and information technology by providing smaller, faster, and more powerful computers and this has been at the forefront of the nanotechnology commercialization . Great examples of how nanotechnology is currently being used in these fields are products such as processors, data storage, and memory components made with nano-materials, TVs, monitors and even smartphone screens that use organic light-emitting diodes (OLED), and waterproof electronics such as smartphones due to the application of nano-coatings

Next, a linear graph of voltage vs. current was collected by turning the voltage between 0.25 V and 0.50 V, then increasing it to slowly approach the maximum voltage value. By doing this, current values were collected for several voltage intervals. All values for this procedure were recorded in a table and plot and are shown in the data section. A linear regression of the voltage vs. current data was then taken to find the experimental resistance value.

They began studying the electrical properties of semiconductors which are non-metallic substances, such as silicon, that are neither conductors of electricity, like metal, nor insulators like wood, but whose electrical properties lie between these extremes. By 1947 the transistor was invented. The Bell Labs research team sought a way of directly altering the electrical properties of semiconductor material. They learned they could change and control these properties by "doping" the semiconductor, or infusing it with selected elements, heated to a gaseous phase. When the semiconductor was also heated, atoms from the gases would seep into it and modify its pure, crystal structure by displacing some atoms. Because these dopant atoms had different amount of electrons than the semiconductor atoms, they formed conductive paths. If the dopant atoms had more electrons than the semiconductor atoms, the doped regions were called n-type to signify and excess of negative charge. Less electrons, or an excess of positive charge, created p-type regions. By allowing this dopant to take place in carefully delineated areas on the surface of the semiconductor, p-type regions could be created within n-type regions, and vice-versa. The transistor was much smaller than the vacuum tube, did not get very hot, and did not require a headed filament that would eventually burn out.

Abstract— Advancement in the VLSI technology leads to the reduction in chip size and increase in chip density. As the chip density increases the overall power consumption and the complexity also increases. As the performance of any system is measured mainly on power consumption, it is recommended to use low power VLSI Design techniques. In this paper, we would discuss the GDI logic and its application in the modeling of adders for Vedic Multiplier design. Adders are of prime importance, the design of reliable and efficient adder for a VLSI based embedded application matters. This paper primarily deals with the design of Ripple Carry Adder, Kogge Stone Adder, and Brent Kung Adder using CMOS and GDI logic. Urdhava Triyagbhayam sutra is used

In order to fix these shortcomings, Mark Kendall and his team have come up with a solution called Nanopatch. The Nanopatch technology is made with

Semiconductors such as silicon and germanium were able to display properties of both conductors and insulators, which made them useful in electronic operations. Germanium was initially used partly because it was easy to work with, but also because silicon was brittle, hard to purify, and unable to be mass produced. In turn, Germanium transistors were invented by John Burdeen, Walter Brattan, and William Shockley in 1947 at Bell Labs, replacing the need for costly and inefficient vacuum tubes (Lecuyer). The transistor was much smaller, more reliable, and provided the same important features of the vacuum tube (“The History of the Integrated Circuit”). Nonetheless, germanium still prompted a problem since it was unstable at high temperatures (“Germanium Transistors”). Silicon’s stability called for the development of a silicon transistor, which was achieved by Texas Instruments in 1954, giving TI a firm reputation that attracted the attention of many emerging engineers, who one of which, was Jack Kilby (Reid

Due to the rapidly growing role of electronics, electronic components, such as diodes, transistors, and integrated circuits are now omnipresent, impacting today’s society. Therefore, it is important to analyze projects and/or experiments related to diodes, transistors, and other components, to determine whether these projects and/or experiments bring us closer to a sustainable society, which is a society that satisfies current needs without compromising posterity’s future needs and fosters consonance between humans and their surroundings[1].

During lab, we have designed circuits proving each of these electrical principles. Now, let's apply this knowledge to a real world application.

PMMA housings (L=45 mm, W=30 mm), McMaster Carr) were designed in AutoCAD and cut with a CO2 laser. Individually cut layers (1.5 – 2 mm) were laminated together using pressure sensitive adhesive films to create rigid plastic housings containing L=25 mm, W=10 mm, H=1.5 mm cavities PDMS pieces containing the microfluidic channels (top) and the flexible nanotextured or plain PDMS surfaces (bottom). Laser-cut holes at the four corners accommodated cylindrical rare earth magnets (K&J Magnetics, 2.54 mm diameter, thickness=1.58 mm) which were then glued in place. Rare earth magnets were embedded in the PMMA and oriented such that the top and bottom housings had opposite magnetic poles facing one another to achieve a simple and self-aligned latching mechanism. The housings compressed the top PDMS channel against the PDMS capture surface and achieved a leak-proof seal (Figure 3.5(b)). Magnetic latching allowed the SEAM platform to be easily sealed and resealed as needed. The tubing was connected to the channel using a barbed fitting (McMaster), and a syringe pump was used to control fluid flow (Harvard Apparatus). The magnetic latching mechanism was sufficient to create a seal that could withstand the maximum

The mote’s size makes energy management a key component. The circuit will contain circuits, a temperature sensor, and A/D converter, microprocessor, SRAM, communications circuits, and power control circuits. Sensors work together with the IC, which will operate from a power source integrated with the platform.

First, the silicon replacement replaces organs of the body to silicon and a kind of chemical. Then, I don't believe that person it will be same as person after replaced by silicon which means it may change the shape or something else. For example, let's assume they replace brain to silicon as we know brain save massive of memories, but can not transfer memories to silicon because it’s impossible to be the same person that have same memories and can remember everything from the past. However, the difference is it will be same person and body, but different thinking or may not remember anything from the past which means the memories have been loosed. Finally, I am assuming my friend wants to make opposite decision, I may prove some evidence that
