Types Of Semiconductor Equipment

Professionals in the semiconductor equipment manufacturing and supplying industry have a reason to cheer

. Semiconductor Equipment & Materials International released a report in November 2010 which predicted that the sales of equipment used to make semiconductors and display devices will increase to a volume of USD 39 billion in 2011. Here are the various types of such equipment that are likely to witness a spurt in sales:

* Dicing Saws: As the name suggests, a dicing saw dices or grooves semiconductor wafers or other kinds of work pieces. For this, it is fitted with spindle with a very thin diamond blade and can work at high speeds. Automatic dicing saws automatically perform the entire sequence of events-loading, aligning, dicing, washing and drying, and finally re-loading.

* Etching Systems: Plasma etching techniques are popularly used in the semiconductor industry. Plasma etching refers to dry etching where the wafer is completely submerged in plasma that contains the etching species. The advantages of employing such a semiconductor equipment is that etching here is isotropic-the chemical etching reactions take place in the same rate in all directions. These systems find most use in those kinds of applications where anisotropy or directionality of etching is needed.

* Wet Benches: The wet bench is a widely used equipment to control motion in a semiconductor. It is actually a robotic machine that transfers the wafers that have been sliced from the silicon ingot, through a line of chemical baths so that they are cleansed and all impurities are removed. This ensures that the wafers are ready for the subsequent stages of preparation-etching and depositing.

* Mask Aligners: A mask aligner aligns a photomask to a wafer. It then exposes the pattern of the photomask to the resist that layers the wafer. This piece of equipment has a significantly greater throughput than the direct-write variety of lithographic tools and hence has found widespread use in the semiconductor manufacturing industry.

ClassOne Equipment is a name to reckon with in the semiconductor equipment supply sector. It is the place to go when you want to invest in a new piece of machinery or want someone to work wonders on a piece of used semiconductor equipment. It stocks equipment of the highest quality from the stables of the some of the most famous brands in the world, brings refurbished semiconductor equipment to their original specifications along with warranties, and also buys surplus semiconductor equipment that ranges from entire process lines to individual tools.
