Title: 이동통신시스템을 이용한 버스 내 실시간 정보 및 광고제공 방법
Inventor: KIM DONG HWON
IPC: H04W4/00
Filed: 2001-08-16
Abstract: 1. 청구범위에 기재된 발명이 속한 분야 
     본 발명은 이동통신시스템을 이용한 버스 내 실시간 정보 및 광고 제공 방법에 관한 것임 
     2. 발명이 해결하고자 하는 기술적 과제 
     버스는 대중교통 수단인 동시에 이동하는 광고매체이다. 버스의 실외광고나 실내광고는 보통 인쇄된 광고판을 이용하고 있다. 그러나 이러한 고정 광고는 광고주에 입장에서는 광고기간과 상관없이 버스광고 대상 수에 비례하여 고정비용이 많이 들어가는 단점이 있었다. 
     또한 고정된 광고판을 달고 운행하는 버스가 넓은 노선을 운행하는 특성을 고려하면 지역광고는 그 의미가 많이 상실되는 경향이 있었음 
     3. 발명의 해결 방법의 요지 
     정해진 노선을 따라 운행하는 버스는 여러 지역을 통과하여 운행하므로 지역별로 나누어 광고내용을 달리하고 광고와 광고 사이에 실시간 정보를 제공하여 광고의 관심을 높일 수 있다. 이를 위해 광고표시를 인쇄된 고정 광고판이 아니라 전광판이나 액정화면을 사용하고 실시간 정보와 광고내용은 개별 버스마다 설치된 이동통신 단말장치에 의해 수신된 데이터를 승객에게 제공하여 가능하게 함 
     4. 발명의 중요한 용도 
     본 발명은 버스 내 광고를 개별적으로 통제하여 광고함으로써 지역상권과 연관된 광고를 버스 통과구간에 나누어 광고할 수 있어 통과 구간별 지역광고가 가능하게 하는 효과가 있으며 이를 통해 버스 통과지역과 연관된 지역광고의 효과를 높이는 효과가 있고, 또한 고정된 인쇄 광고판에 의한 광고가 아닌 광고이므로 광고물제작과 버스 내 광고물 부착시의 비용을 절약할 수 있는 효과가 있으며, 원하는 회수만큼을 원하는 통과 지역에 의뢰하여 광고할 수 있어 단 기일에 집중적인 광고효과를 얻을 수 있는 효과가 있으며, 실시간 정보에 의한 승객들의 관심을 얻어 광고의 효과를 높일 수 있다는 효과가 있음

Title: 나노미터 크기의 광도파로 제작방법
Inventor: LEE GEUN HYOUNG
IPC: G02B6/10
Filed: 2001-11-06
Abstract: 본 발명은 나노미터 크기를 갖는 광도파로 제작 기술로서, 특히 기판의 표면에 나노미터 크기를 갖는 표면 구조를 형성시킴으로서 기판 위에 증착되는 광도파로 재료를 기판의 나노미터 크기의 표면 구조에만 증착되도록 함으로서 나노미터 크기의 광도파로를 제작하는 방법에 관한 것이다. 
     근래, 박막을 이용한 광도파로(광디바이스)의 개발이 큰 주목을 받고 있다. 이와 같은 광도파로(광디바이스) 제작에 있어 도파로의 제작은 필수 불가결한 공정이다. 또한, 광집적회로에 있어서 많은 광소자들이 광도파로상에서 만들어지고 있다. 
     박막을 이용한 광도파로의 제작에는 주로 사파이어 기판을 사용하며, 광도파로의 재료로 LiNbO 3 또는 LiTaO 3 의 박막을 증착한 후 사진·석판 인쇄(Photo-lithography) 방법으로 도파로 패턴을 형성하고 있다. 사진·석판 인쇄 방법으로 제작하던 종래의 방법은 석판 인쇄 공정에서 빛을 이용하기 때문에 빛의 회절의 특성으로 인하여 빛의 파장보다는 작은 패턴을 절대로 형성할 수 없다. 100nm(나노미터) 이하의 크기를 갖는 도파로의 제작은 매우 어려우며, 거의 불가능하다. 본 발명은 사파이어 기판 표면에 나노미터의 높이를 갖는 스텝들을 형성시킨 후 과도파로 재료의 박막 증착 시 증착 물질의 원자 또는 분사들이 스텝에 부착되도록 하여 나노미터 크기의 광도파로를 형성하는 것을 목적으로 한다. 
     100 나노미터 이하의 사이즈를 갖는 도파로를 형성하기 위하여 대기 중 900℃ 이상의 온도에서 30분 이상 사파이어 기판을 열처리하면 기판의 전 표면에 직선의 스텝들이 형성된다. 형성된 스텝의 높이는 C-면 기판인 경우 최소 0.22±0.22nm 이상, A-면 및 R-면인 경우 각각 0.25±0.02nm, 0.36±0.02nm 이상이다. 처리 온도를 높이거나 처리 시간을 길게 하면 스텝의 높이는 스텝 다발(bunching) 현상에 의해 (최소 높이 x 정수배)의 높이를 나타낸다. 이러한 사파이어 기판을 고진공 증착 장비에 넣고 도파로 물질을 증착시킨다. 예를 들면, 펄스 레이저 증착빔(PLD)의 경우, 사파이어 기판을 넣고 10 -6 Torr이하의 진공도까지 진공을 뽑은 후 산소를 주입한 다음 1mTorr 이상의 압력이 되도록 한다. 기판을 600℃이상으로 가열하면서 LiNbO 3 를 증착시키면 기체 상태의 LiNbO 3 의 원자 또는 분자의 전부 기판 표면의 스텝에 부착되어 LiNbO 3 의 핵이 생성되며, 부착되는 양이 증가할수록 스텝을 따라 부착물이 전부 연결된 선모양의 구조가 형성된다. 스텝의 높이가 약 10nm이고 증착막의 두께가 약 10nm 박막 두께의 양일 경우, 가는 LiNbO 3 도파로선의 폭은 약 80nm이다. 스텝의 높이와 증착량에 따라 도파로선의 폭은 조절이 가능하다. 도파로의 간격은 스텝 사이의 간격을 조절함으로서 가능하며, 스텝간 간격은 기판 표면의 오차(misorientation angle), 열처리 온도 및 시간의 조절로 가능하다. 
     본 발명을 적용한 방법은 기존의 사진·석판 인쇄 공정으로는 제작이 불가능한 100nm 크기 이하의 광도파로 제작이 가능하여 나노 광스위치, 나노 광변조기, 나노 비선형 광레이저 등의 개발 및 초고집적 나노 광디바이스의 개발에 중요한 역할을 할 수 있다. 특히, 복잡한 사진·석판 인쇄 공정의 생략이 가능하게 되어 공정의단순화 및 제조 경비의 절감을 가져올 것이다.
