newCheaper, higher quality GaN freestanding substrates using N polarity control.

概要

Nitride semiconductor free-standing substrate production method
https://www.t-technoarch.co.jp/data/anken_en/T14-121.pdf
This invention relates to a technique for producing high-quality nitride semiconductor freestanding substrates at a lower cost. The invention also includes the use of SCAlMgO4 substrates as seed crystals. The dislocation density of nitride semiconductors on this substrate becomes lower. By controlling the crystal polarity, the crystal diameter can be expanded as well as the thickness of the nitride semiconductor.

従来技術との比較

It is possible to fabricate freestanding nitride semiconductor substrates with lower through-dislocation density than conventional substrates. Furthermore, the cleavage property of ScMgAlO4, which serves as the substrate, facilitates the exfoliation of the nitride semiconductor and reduces the cost of substrate fabrication.

特徴・独自性
  • Usage of ScAlMgO4 as a source substrate.
  • Expansion of crystal diameter by using N-polar growth
  • When ScAlMgO4 is used as the seed crystal and AlN is formed as the surface protective layer of this crystal, the surface shall be further nitrided after oxidation of the surface.
  • The main surface of the seed crystal shall be inclined 0.4 to 1.2° from the c-plane.
実用化イメージ

This invention is to provide high-quality, low-cost free-standing nitride semiconductor substrates for optical devices such as light-emitting diodes and lasers, and transistors operated under high power, high voltage, and high frequency. Companies are expected to verify the commercialization of the product.

Chemical imaging devices which operate in severe environments

NEXT
PREV
特徴・独自性
  • We developed both pH and Cl- imaging plates, which can visualize the pH and Cl- concentration on metal surfaces in acidic environments. The pH range is from 3.0 to 0.5, and Cl- concentration up to 4 M can be measured. Fluorescent dyes are successively used for pH and Cl- imaging in the field of biology, but their sensitivity tends to be insufficient in acidic and/or highly concentrated chloride solutions. A glass plate with a sol-gel sensing layer, which contains a pH indicator or a Cl- sensitive florescent dye was fabricated and validated using the solutions with various pH values and Cl- concentrations. Changes in the pH and Cl- distribution on stainless surface in an acidic environment were measured quantitatively.
実用化イメージ

The newly developed imaging plates can be used to investigate the mechanism of various chemical reactions, such as corrosion, which occurs in an acidic environment. Micro-flow imaging using our sensing technique will be a promising approach to understand the catalytic chemistry of metal surfaces.

Chemical Recycling of Problematic Polymeric Wastes

NEXT
PREV
特徴・独自性
  • The Yoshioka Laboratory works on the recycling of various polymers by thermal and wet processes. Plastics such as poly(ethylene terephthalate) (PET), polyvinyl chloride (PVC), and high impact polystyrene (HIPS) cause serious problems during their recycling for the recycling process and the environment. However, these materials can also be seen as a resource for new materials. The decarboxylation of PET results in high yields of benzene that can be used as a chemical feedstock. Another important feature is the dehalogenation of flame retarded plastics and PVC. Dechlorinated plastic waste can be an important source for hydrocarbons, which can be used as fuels and chemical feedstock. The chemical modification of PVC offers the possibility of new materials with new properties. Modified PVC can be used as antibacterial material or as a material with ion exchange properties. The removal of brominated flame retardants from HIPS leads to higher recovery rates of styrene during thermal processing. When a wet process is used, the resulting flame retardant free HIPS can be reused.
実用化イメージ

We are eager to help companies to overcome their problems during recycling and recovery, and provide solutions for the treatment of waste materials.

NEXT
PREV
特徴・独自性
  • Maximal resection and functional preservation, are often conflicting, but are both important factors to improve patient’s quality of life. Pulsed jet system is designed to achieve this goal by removing lesions without impairing small diameter vessels (100 μm - ). Standardization and specialization of surgical procedures is expected to achieve more easily compared to conventional surgical device using pulsed jet system. We have already reported significant increase of tumor removal rate, significant reduction of intraoperative blood loss and operation time in difficult lesions in the vicinity of sella turcica and skull base through expanded transsphenoidal approach. The system can eject small amount ( - 2 μl) of high speed liquid (- 50 m/s) for minimally invasive surgery, such as endoscopic, catheter, and microscopic surgery. The system is now under stage to expand clinical application outside the field of neurosurgery, and we are expecting new collaboration who can deal with increasing safety, effectiveness, differentiation from conventional instruments, accessibility.
