Abstract: 본원 발명은 미세한 접속공을 A1계 재료로 매입하고, 저저항성 및 우수한 배리어성을 동시에 충족시키는 배선형성방법에 관한 것이다. 본원 발명은 배리어메탈의 구조를 향상시킨 것이다. 본원 발명에는 (a) 변형된 SALICIDE법에 의한 TiSi₂층 및 Ti층의 형성과, (b) 미정질화된 Ti계 재료층이 사용된다. TiSi₂층은 예를 들면 얇은 SiO₂층을 통하여 실리콘기판과 Ti층을 반응시킴으로써 자체 정합적으로 형성되며, 낮은 시트저항과 치밀한 막질뿐만 아니라 우수한 배리어성을 나타낸다. Ti층은 TiSi₂층 위에 적층되어 A1계 재료층에 대하여 높은 습윤성을 나타낸다. 비정질화 Ti계 재료층은 다결정 TiN층에 N₂이온주입함으로써 형성되며, A1확산경로로서 작용하는 결정입계가 파괴되기 때문에 우수한 배리어성을 나타낸다. 상기 두 층은 모두 지금까지 우수한 배리어성을 나타내는 재료층으로 사용되었던 TiON층에 비하여 시트저항이 낮고, A1계 재료층에 대하여 우수한 습윤성을 나타내므로, 고신뢰성의 콘택트형성이 가능하다.

Title: Process for preparing aqueous suspension
Inventor: NAKAYAMA HISAYUKI
IPC: A61K9/00
Filed: 1991-07-11
Granted: 1999-05-01
Abstract: A process for preparing a stable aqueous suspension containing microcrystals of 5-(3-ethoxy-4-n-pentyloxyphenyl)thiazolidine-2,4-dione suitable as eye drops for treating praticularly corneal deseases, which comprises adding an acid to an aqueous solution of 5-(3-ethoxy-4-n-pentyloxyphenyl)thiazolidine-2,4-dione and at least one member selected from among polyvinyl alcohol, polyvinylpyrrolidone, hydroxypropylmethylcellulose, methylcellulose and hydroxyethylcellulose, said solution having a pH of at least 8, to lower the pH below 7.

Title: Manufacturing method of metal plug in contact-hole
Inventor: CHOE KYUNG-KEUN
IPC: H01L21/768
Filed: 1993-02-17
Granted: 1996-03-26
Abstract: The method for making a metal plug(5) to electrically connect upper and lower wiring layers in a semiconductor device comprises: preparing a semiconductor substrate (1) including a wiring layer and insulating film(2) having a contact hole(3) on the substrate; and forming a poly-Si film(6) overall. A photoresist film is formed at the bottom of the contact hole, and exposed poly-Si removed, followed by removal of the photoresist. A metal film is formed overall and annealed to react with the poly-Si to form a silicide film(4) at the bottom of the contact hole, unreacted metal is removed and the hole is filled with a second metal to form a metal plug(5) in the hole. The metal plug has a uniform surface, a junction consumption reaction is prevented, and the wiring layer has a uniform thickness.

Patent KR-950013315-B1 (KR)
Title: Retreatment method for sludge containing fluorine
Inventor: HONG YONG-HO
IPC: C01F17/00
Filed: 1993-05-07
Granted: 1995-11-02
Abstract: Re-treatment of the residue of rare earth fluoride, which is produced on the removal of fluorine ion from waste water by rare earth compound, is characterized by heat treating dried residue at 400-1300 deg.C for 30 mins to 15 hrs. After heat treatment one or a mixture of two or more of rare earth oxide, rare fluoride and rare earth oxyfluoride are produced. Furthermore heat treated residue is leached with an inorganic acid (e.g., 1.5-20% hydrochloric acid) to improve the quality of rare earth oxide.
