Integrated Circuit Fabrication Masks
A mask in IC Fabrication is a master template for an IC design. A light-sensitive material, is applied on the wafer. The mask as well as a wafer are inserted in a lithography scanner. More ...
Integrated Circuit Manufacturing Pattern Transfer
The integrated circuit manufacturing photolithographic pattern transfer process requires a variety of physical and chemical processes performed on a semiconductor substrate. More ...
Electrical Charge
The forces between electrically charged particles are used in technologies such as printers, pollution filters, and spray guns used for painting cars and trucks. Static electricity is the study of phenomena that involve an imbalance of electrical charge. Although creating this imbalance typically requires moving charge around, once the imbalance is created, it often remains static for a long time. More ...
Planar Integrated Circuit Fabrication
The key unit process steps in IC fabrication, include oxidation, photolithography, etching, ion implantation, and metallization. Here, we describe the oxidation steps. More ...
Integrated Circuit Manufacturing Bipolar Technology
Bipolar junction transistors (BJTs) are still used in integrated circuits (ICs) for switching, signal amplification, and radio-frequency circuits because they are faster than CMOS transistors. More ...
Integrated Circuits
An integrated circuit (IC) is a thin rectangular piece of semiconductor upon which, using a photographic process, thousands of electronic components, and the conducting paths to connect them, are printed. The types circuits that can be etched into a semiconductor chip range from amplifiers to logic gates and even microprocessors with millions of transistors. More ...
Integrated Circuit Fabrication Photolithography
Photolithography is the process of transferring patterns on a mask to a thin layer ofphotoresist covering the surface of a semiconductor wafer. These patterns define the various regions in an integrated circuit, such as the implantation regions, the contact windows, and the bonding pad areas. More ...
Modern Semiconductor Manufacturing
The modern semiconductor manufacturing process sequence is the most sophisticated and unforgiving volume production technology that has ever been practiced successfully. It consists of a complex series of hundreds of unit process steps that must be performed very nearly flawlessly. More ...
CrowPi is a Raspberry Pi Project System Housed in a Laptop-Like Body
Learn everything about computers with this amazing Raspberry Pi kit housed in a laptop-like body. More ...
Electrical Transformers
A transformer is an electrical device that uses the principle of magnetic induction to step voltage up or step down. Inversely it increases or decreases the current available at the different voltages. More ...
Integrated Circuit Manufacturing Packaging
Before ICs can be put to their intended use they must be packaged. The package is responsible for interconnecting, powering, cooling, and protecting the IC. More ...
RMS Used in AC Circuit Analysis
Because the value of an AC signal is continuously varying, it would be difficult to use formulas such as ohms law. In the specific case of a sine wave, the Root Mean Square (RMS) of the wave is used instead. More ...
Transformers
Transformers work according to the principle of electromagnetic induction. If the first coil carries sine-wave ac of a certain frequency, then the induced current will be sine-wave ac of the same frequency in the second coil. More ...
Magnetism Permeability and Retentivity
Permeability is a property of a material that describes the ease with which magnetic flux is established in the material. Retentivity is a materials ability to retain a certain amount of residual magnetism after the magnetizing force is removed. More ...
