  1. Wafer backgrinding

    Wafer backgrinding is a semiconductor device fabrication step during which wafer thickness is reduced to allow for stacking and high density packaging of integrated circuits IC . ICs are being produced on semiconductor Wafer electronics wafers that undergo a multitude of processing steps. The silicon wafers predominantly being used today have diameters of 20 and 30 cm. They are roughly 750 micrometre m thick to ensure a minimum of mechanical stability and to avoid warping during high temperature processing steps. Smartcards, USB memory sticks, smartphones, handheld music players, and other ultra compact electronic products would not be feasible in their present form without minimizing the size of their various components along all dimensions. The backside of the wafers are thus ground prior to wafer dicing where the individual microchips are being singulated . Wafers thinned down to 75 to 50 m are common today. ref name itrs09 http www.itrs.net International Technology Roadmap for Semiconductors 2009 edition, page 12 53. ref The process is also known as Backlap ref name an900 http www.st.com stonline books pdf docs 5038.pdf Introduction to Semiconductor Technology , by ST Micro electronics, page 6. ref or Wafer thinning . ref name sfe http www.siliconfareast.com backgrind.htm Wafer Backgrind at Silicon Far East. ref See also Back illuminated sensor References references Category Semiconductor device fabrication ...   more details

It is because of this neutral taste that many wineries and food aficionados around the world prefer using the Bremner wafer as a wine tasting cracker. This neutral taste, however is seen as a drawback by some because it means the crackers are nearly tasteless when eaten alone. History The Bremner Biscuit company was founded by David F. Bremner , who first introduced his brands of bread to the fire victims of the great fire in Chicago . Although the Bremmer Wafer wasn t invented until 1902, David Bremner s company was modestly successful prior to its invention. When his sons took over the business When date February 2011 they developed the Bremmer Wafer, which is still sold today. The company remained in Chicago until 1984, when they moved to Denver , where it remains today. The Bremner Biscut Company was bought by Dare Foods in September 1999. Although he is no longer the CEO, Neil Bremner 5th generation runs Dare s baking division.

Wafer level packaging has the ability to enable true integration of wafer fab, packaging, test, and burn in at wafer level in order to streamline the manufacturing process undergone by a device from silicon start to customer shipment. Wafer level packaging basically consists of extending the wafer fab processes to include device interconnection and device protection processes. Most other kinds of packaging does wafer dicing first, and then puts the individual die in a plastic package and attaches the solder bumps. Wafer level packaging involves attaching the top and bottom outer layers of packaging, and the solder bumps, to integrated circuit while still in the wafer, and then wafer dicing .

  1. Non-contact wafer testing

    Wafer testing is a normal step in semiconductor device fabrication , used to detect defects in integrated circuits IC before they are assembled during the IC packaging step. Traditional contact wafer testing Probing ICs while they are still on the wafer normally requires that contact be made between the automatic test equipment ATE and IC. This contact is usually made with some form of mechanical probe. A set of mechanical probes will often be arranged together on a probe card, which is attached to the wafer prober. The wafer is lifted by the wafer prober until metal pads on one or more ICs on the wafer make physical contact with the probes. A certain amount of over travel is required after the first probe makes contact with the wafer, for two reasons to guarantee that all probes have made contact to account for non planarity of the wafer li to break through the thin oxidized layer if the metal pad is Aluminum on the pad li There are numerous types of mechanical probes available commercially their shape can be in the form of a cantilever , spring device spring , or membrane, and they can be bent into shape, stamped, or made by Microelectromechanical systems processing.

  1. Multi-project wafer service

    Multi Project Chip MPC or Multi Project Wafer MPW services integrate onto microelectronics wafers a number of different integrated circuit designs from various teams including designs from private firms, students and researchers from universities. Because IC fabrication costs are extremely high, it makes sense to share mask and wafer resources to produce designs in low quantities. Worldwide, several MPW services are available from government supported institutions or from private firms including MOSIS, CMP and Europractice. The first well known MPW service was MOSIS Metal Oxide Silicon Implementation Service , established by DARPA as a technical and human infrastructure for VLSI . MOSIS began in 1981 after Lynn Conway organized the first VLSI System Design Course at M.I.T. in 1978. MOSIS primarily services commercial users now but continues to serve university students and researchers. With MOSIS, designs are submitted for fabrication using either open i. e., non proprietary VLSI Design rule checking layout design rules or vendor proprietary rules. Designs are pooled into common lots and run through the fabrication process at foundries. The completed chips packaged or unpackaged are returned to customers. Many silicon fabrication facilities offer MPW runs or a company can produce its own MPW, e.g. combine several of its own designs to form one wafer completely owned by the company. In the latter case, it may be profitable to use most of the wafer for production chips and a small portion for producing prototypes of next generation chips.
