SK group accelerates vertical integration of Semiconductors
According to Korean media ETNews reported that the industry news, SKInnovation to SK Hynix supply products for the purpose, is engaged in photoresist (Photoresist) research and development. Recently, SKInnovation has given a small amount of photoresist samples to SK Hynix for testing, followed by feedback to improve quality, towards the mass production target forward. Photoresist is used in the exposure process of silicon wafers to form a circuit pattern with the light acting through the mask. Exposure equipment and materials are divided into G-line, I-line, KrF, ArF and extreme ultraviolet light (EUV) according to the exposure wavelength, among which ultra violet light is the most advanced. SKInnovation develops a KrF photoresist used for the production of 3DNANDFlash. When coated on a wafer, more than 10 thick film must be formed, so that the memory cell (Cell) can be successfully stacked into a vertical structure. The photoresist material market is mainly composed of ArF and extreme ultraviolet (Shin-EtsuChemical), Sumitomo ShinEtsu chemical Chemical (SumitomoChemical), Tokyo chemical industry (TOK), JSR and other Japanese companies grasp; South Korea world east Macon (DongjinSemichem) and Merck (Merck) for the 3DNANDFlashKrF photoresist technology difficulty is relatively low the. SKInnovation said that the company began to study 2 years ago, such as spark inhibitors and other electronic materials, in the hope that the oil and oil fields accumulated technical energy, but also in the special chemical materials market gains. Following the inclusion of Hynix, SK group began to strengthen its semiconductor materials and components business with the acquisition strategy. In January 2016, we purchased OCIMaterials, a semiconductor specialty gas producer, and renamed it SKMaterials. SKMaterials produces three fluorinated nitrogen (NF3), which is used to clear the residual material in the cavity of the semiconductor machine, and the global market share is the first. In 2016, SKMaterials and Japan TriChemicalLaboratories and Showa electrician (ShowaDenko) jointly established subsidiaries SKTriChem, SKShowaDenko. SKTriChem produces zirconium (Zr) precursor (Precursor), high dielectric (High-K) evaporation material; SKShowaDenko produces etching gas three fluorine methane (CH3F). All two of these materials will be supplied to Hynix SK. At the beginning of the 2017 SK group once again to the LG Group (LGGroup), LG Siltron silicon wafer buy over half of equity. The previous SK Hynix respectively to Sumco, SunEdisonSemiconductor, Shin Etsu chemical, Siltronic and LG Siltron 5 suppliers of procurement of silicon wafer, the future will increase the purchasing volume of LG Siltron. The industry said that the 2015 SK Group Chairman Cui Taiyuan for the group in 2020 200 revenue target trillion won ($177 billion 900 million), and selected a number of areas as new species cause cultivation, the largest of which is the semiconductor and related materials and components business. Later, SK group's major subsidiaries have been involved in research and development, such as SKC's subsidiary, SKCSolmics, which is developing MaskBlank. Japan's Hoya and film forming Optoelectronics (Ulcoat) are the main suppliers of the mask base market, and the South Korean S&STech has also independently developed and marketed its products to overseas markets. SKCSolmics will successfully increase revenue if it succeeds in bringing the mask base into commercial use. SKInnovation development of 3DNANDFlash KrF photoresist reported that all kinds of electronic materials such as photoresist, chemical products are still in the development stage, whether mass production, but also need to be carefully assessed to determine.
