ADC OPTIMISES NEAR FIELD HOLOGRAPHY MANUFACTURING PROCESS.Through its recent acquisition of IBSEN Micro Structures A/S, ADC (1) See A/D converter. (2) (Apple Display Connector) A peripheral connector from Apple that combines digital video display, USB and power in one cable. has optimized a manufacturing process, where very small nanometer structures can be transferred and replicated in high volume manufacturing setups. Target application of the Near Field Holography (NFH NFH Naval Frigate Helicopter NFH No Frequency-Hopping ) process is within the optical industry especially in the telecom industry, where the need for integrated optical circuits such as distributed feedback (DFB DFB acronym for dark, firm, dry meat. Called also dark cutting beef. ) lasers and other grating-based integrated components is growing rapidly. ADC's NFH process, together with its Phase masks, enables replication of structures as small as 100 nanometers in large-scale manufacturing using cost-effective contact print technology to manufacture optical gratings. E-beam and crossed laser beam alternatives are less practical in a production environment due to high costs of ownership. Also, optical steppers presently lack the resolution capability in addition to a high cost-of-ownership value. ADC has pioneered the commercialization of this process together with Karl Suss, the world leader in mask aligners for the semiconductor industry. Per Ibsen, director of research and development at ADC in Denmark, states that "Although the basic principles are easy to understand, as we are dealing with a lithographic lith·o·graph n. A print produced by lithography. tr.v. lith·o·graphed, lith·o·graph·ing, lith·o·graphs To produce by lithography. process well known from the semiconductor industry, there is the important difference that we are operating with much smaller structures, which adds complexity to the process. believe that the NFH process will be adapted by many companies in the semiconductor, optical and sensor industries around the world, since the benefits from our process are so convincing in terms of cost savings and productivity". Karl Suss is a global supplier of manufacturing equipment and process technology for advanced packaging, microelectronics and MEMS (MicroElectroMechanical Systems) Tiny mechanical devices that are built onto semiconductor chips and are measured in micrometers. In the research labs since the 1980s, MEMS devices began to materialize as commercial products in the mid-1990s. market. With over 6,000 systems installed, SUSS products include coating and developing systems, proximity lithography systems, substrate bonders, flip chip A chip packaging technique in which the active area of the chip is "flipped over" facing downward. Instead of facing up and bonded to the package leads with wires from the outside edges of the chip, any surface area of the flip chip can be used for interconnection, which is typically done bonders and probe systems. Headquartered in Munich, Germany, Suss operates 9 manufacturing, sales and service centers in North America North America, third largest continent (1990 est. pop. 365,000,000), c.9,400,000 sq mi (24,346,000 sq km), the northern of the two continents of the Western Hemisphere. , Europe, Asia and Japan. ADC is The Broadband Company(TM). ADC's network equipment, software and integration services make broadband communications a reality worldwide by enabling communications service providers to deliver high-speed Internet, data, video and voice services to homes and businesses. ADC (Nasdaq:ADCT ADCT Adaptive Discrete Cosine Transform ) has annual sales of over $2.8 billion and employs more than 20,900 people worldwide. |
