Single Crystal Germanium Wafer

PAM-XIAMEN offers 2”, 3”, 4” and 6” germanium wafer, which is short for Ge wafer grown by VGF / LEC. Lightly doped N and P type Germanium wafer can be also used for Hall effect experiment. At room temperature, crystalline germanium is brittle and has little plasticity. Germanium has semiconductor properties. High-purity germanium is doped with trivalent elements (such as indium, gallium, boron) to obtain P-type germanium semiconductors; and pentavalent elements (such as antimony, arsenic, and phosphorus) are doped to obtain N-type germanium semiconductors. Germanium has good semiconductor properties, such as high electron mobility and high hole mobility.

3. Germanium Wafer Process

With the advancement of science and technology, the processing technique of germanium wafer manufacturers is more and more mature. In the production of germanium wafers, germanium dioxide from the residue processing is further purified in chlorination and hydrolysis steps.
1) 고순도 게르마늄 영역 정제하는 동안 얻을 수있다.
2) 게르마늄 결정은 초크 랄 스키 프로세스로 제조된다.
3) 게르마늄 웨이퍼는 여러 절단, 연삭, 및 에칭 공정을 통하여 제조된다.
4) 웨이퍼 세정 및 검사된다. 이 과정에서 웨이퍼 사용자 요구 사항에 따라 연마 한면 광택 또는 양면이며, 에피 준비 웨이퍼 온다.
5)The thin germanium wafers are packed in single wafer containers, under a nitrogen atmosphere.

4. Application of Germanium:

게르마늄 빈 또는 창은 야간 및 상업용 보안, 화재 진압 및 산업용 모니터링 장비에 대한 열 감지 이미징 솔루션에 사용됩니다. 또한, 이들은 레이저에 대한 분석 및 측정 기기 용 필터, 원격 온도 측정 용 창문, 거울과 같이 사용된다.

Thin Germanium substrates are used in III-V triple-junction solar cells and for power Concentrated PV (CPV) systems and as an optical filter substrate for a longpass SWIR filter application.

5. Test of Germanium Wafer:

The resistivity of the crystal germanium wafer was measured by Four Probe Resistance Tester, and the surface roughness of Germanium was measured by profilometer.
