Information @ a Glance

General
  • The glass substrate is the portion of the mirror in which solar energy is transmitted. It is composed of a float glass with high transmission characteristics in the visible and infrared ranges and is configured to transmit visible light and infrared radiation.
  •  The first side contains a reflective layer for reflecting the solar energy gathered. This is then transmitted through the glass substrate to the second side. The second side that is curved then reflects the solar energy back through the glass substrate and back out the first side of the glass.

Process

  • After several years of research Komag has achieved major breakthroughs in process technologies associated with the manufacture of glass substrates. Such process advancements may offer the potential to approximately halve the cost of future glass substrates.
  •  Furthermore, the cost of glass substrates manufactured under these new processes is expected to be less expensive than equivalent aluminum-based substrates. Over 90% of the disks manufactured today are aluminum-based disks.
  • Glass slides wafers are often cleaned by a solvent clean, followed by a dionized water (DI) rinse, followed by a mild acid clean, DI rinse and blow dry. This is a level-1 process and requires basic INRF safety certification. The use of dangerous chemicals requires that the user may not perform the process alone.

Technology

  • In FPD technology, Process of Coating for Glass Substrate and/or CF is an extremely important process. KURAMOTO's "Coating technology" enjoy a high reputation of customers Electrostatic chucks (ESCs) in dry etchers for thin film transistor-liquid crystal display (TFTLCD) fabrications were investigated theoretically, the ESCs should be used. By applying the simple ESC model, the voltage region for the stability of glass substrate was obtained.
  • To transport delicate glass substrates without damaging them, Sharp developed original transporting technology. As a result, Sharp can input 60,000 glass substrates per month into the manufacturing line (at Kameyama Plant No. 1), making it possible to produce a stable and highly efficient supply of large LCD panels.
  • In order to mass-produce larger LCD panels, Sharp adopted new technology that involves dropping liquid crystals onto the surface of a glass substrate. Through this method, which looks simple but is actually quite difficult, Sharp pioneered the way to mass production of large LCD panels.

Market

  • PDP has excellent features suitable for larger display and highly minute pictures, and its demand is rapidly increasing worldwide. Central Glass Co., Ltd. Company will soon start sales activities targeting annual sales of ¥3 billion in 2005. Central Glass Co., Ltd. Company currently produces substrates for flat panel displays such as VFD (Vacuum Fluorescent Display), TN-LCD, STN-LCD and TFT-LCD.
  • Demand for TFT liquid crystal panels is now in full swing for television sets as well as for personal computers, and is expected to rise at an annual rate of 20% on a unit basis. In addition, many TFT liquid crystal panel manufacturers currently produce panels by using large 6th generation or larger mother glass. Production of panels with using 10th generation glass substrates, the world’s largest, is also scheduled.
  • Sales in the glass and related operations segment amounted to ¥625,240 million ($5,768 million), and accounted for 45.3% of total sales, including intersegment net sales and transfers.
  •  The segment’s operating income was ¥35,852 million ($331 million). Sales of flat glass and construction materials expanded, supported by continuing firm demand in Japan for double-glazing glass units, which offer excellent insulation.

Application

  • One approach to synthesising HDOAs consolidates the principles of solid-phase nucleic acid synthesis and photolithography adapted from the semiconductor manufacturing arena. This approach allows for the synthesis of oligonucleotides in situ on glass substrates.
  • For thin solar cell application glass would be a very good material, because it offers many advantageous properties. It offers a very good chemical resistance which is needed both for the processing of the solar cells as well as for its long term application to be resistant to atmospheric attack and ultraviolett radiation.
  •  Its temperature stability is needed for the processing. Good transmission properties are also needed, which are offered by glass as well as a smooth surface.
  • The use of CG Silicon technology to form circuitry directly on the glass substrate is what lies beneath the outstanding features of System LCDs-high resolution, low power consumption, narrow frame, and multiresolution display capability (Fig. 6)-and we have been receiving high praise from users.
