IC Fabrication Techniques

john February 16, 2011 5 Comments
IC Fabrication Techniques In this article, the different processing techniques that are needed for IC , transistor and diode fabrication are listed. A small procedure of the fabrication process is also explained. In a monolithic IC, all the circuit components are fabricated into or top of a block of silicon which is referred to as chip or die. Metallization patterns are required to make interconnections between the components present inside the chip. It must also be noted that the...

Understanding FPGA and CPLD

jojo April 22, 2010 No Comments
Introduction In the earlier 60’s it was discrete logic used by electronic industry. The digital system would look like noodle like maze of wiring between components. Once it is built it will be difficult to do rework on it. Sometimes the designers would forget what they have designed for! Manufacturing such systems was very difficult and redesign will be so eye-shutting just like making a PCB every time we redesign. The chip manufactures resolved this issue by placing an...

Cadence Design Framework II All the tools from cadence for the VLSI design process use the same unique database called Design Framework II (DFII). It is a binary database that stores the data as objects. In the world of Electronic Design Automation (EDA), there are different types of objects and each representing a distinct concept. The cellviews, symbols, instances, terminals etc are different types of objects. The Design Framework II database can store both the physical information as well...

VLSI Design Flow

Jais Abraham July 26, 2018 No Comments
The chip design includes different types of processing steps to finish the entire flow. For anyone, who just started his carrier as a VLSI engineer has to understand all the steps of the VLSI design flow to become  good in his area of operations. There are different types of design procedures for analog/digital designs and FPGA designs. The analog design is mainly focusing on the back end design of a chip while FPGA on front end design. Front End...
