Trimethylaluminum (TMal), senzvimbo yesimbi-organic (MO), inoshandiswa zvakanyanya muindasitiri yesemiconductor uye inoshanda senzira huru yekuisa atomic layer deposition (ALD), chemical vapor deposition (CVD), uye metal-organic chemical vapor deposition (MOCVD). Inoshandiswa kugadzira mafirimu ane aruminiyamu akachena zvakanyanya, akadai sealuminium oxide nealuminium nitride. Pamusoro pezvo, TAl inoshandiswa zvakanyanya se catalyst uye mubatsiri wayo mu organic synthesis uye polymerization reactions.
Trimethylaluminum (TMAI) inoshanda senzira yekuisa aluminium oxide uye inoshanda seZiegler-Natta catalyst. Ndiyo nzira inonyanya kushandiswa yealuminium mukugadzira metal-organic vapor-phase epitaxy (MOVPE). Uyezve, TMAI inoshanda se methylation agent uye inowanzoburitswa kubva mumaroketi anorira senzira yekuongorora mapatani emhepo yemudenga.

Cherechedza:
Pamusoro pezvose, tarisa PPM nehuremu hwesimbi, uye ND = haina kuonekwa
Nzira yekuongorora: ICP-OES/ICP-MS
Mhedzisiro yeFT-NMR (LOD yeFT-NMR tsvina yeorganic uye ine oxygen ndeye 0.1ppm):
Gadziriro yeokisijeni <0.2 ppm (Yakayerwa muFT-NMR)
1. Hapana tsvina yeOrganic yakawanikwa

Chii chinoshandiswa Trimethylaluminum (TMAI)?
Trimethylaluminum (TMA)- Mashandisirwo uye Mashandisirwo
Trimethylaluminum (TMA) imusanganiswa we organoaluminium wakachena zvakanyanya unoshanda senzira yakakosha mune mamwe maindasitiri ekugadzira epamusoro-soro. Kushanda kwayo zvakanyanya uye kumanikidzwa kwemhepo kunoita kuti ive chinhu chinosarudzwa chekuisa mafirimu chaiwo ane aruminiyamu mumagetsi netekinoroji yesimba, pamwe nechikamu chikuru mukugadzirwa kwepolyolefin.
TMA yedu yakagadzirwa nemazinga akasimba ekuchena, ine kutonga kwakasimba pamusoro pezvinhu zvakachena, zvakaiswa oxygen, uye organic kuti ive nechokwadi chekuti inoshanda zvakanaka mumabasa ako anonyanya kuoma.
Zvishandiso Zvikuru uye Maindasitiri:
1. Kugadzira Semiconductor & Microelectronics
Muindasitiri yesemiconductor, TMA inokosha pakuburitsa mafirimu matete ane hunyanzi hweatomu.
* High-k Dielectrics: Inoshandiswa muAtomic Layer Deposition (ALD) uye Chemical Vapor Deposition (CVD) kugadzira mafirimu matete ealuminium oxide (Al₂O₃) akafanana, asina maburi, ayo anoshanda sehigh-k gate dielectrics mumatransistors epamusoro uye zvishandiso zvekurangarira.
* Compound Semiconductors: Inonyanya kufarirwa nealuminium sosi muMetalorganic Vapor Phase Epitaxy (MOVPE) yekukura macompound semiconductors emhando yepamusoro eIII-V. Zvinhu izvi zvakakosha pa:
* Magetsi Anoshandiswa Nenguva Dzepamusoro: (semuenzaniso, AlGaAs, AlInGaP)
* Optoelectronics: (semuenzaniso, AlGaN, AlInGaN)
2. Simba Rakachena & Photovoltaics
TMA inoita kuti pave nekushanda nesimba uye kugara kwenguva refu mumichina yesimba rezuva.
* MaLayers ePassivation: Akaiswa kuburikidza neALD kana Plasma-Enhanced CVD (PECVD), mafirimu ealuminium oxide (Al₂O₃) kubva kuTMA anopa passivation yakanaka yesurface yemasero ezuva ecrystalline silicon. Izvi zvinoderedza zvakanyanya charge carrier recombination, zvichikonzera kubudirira kukuru mukushanda zvakanaka kwemasero uye kugadzikana kwenguva refu.
3. Mwenje wepamusoro neDisplay (LED)
Kugadzirwa kwema LED anopenya zvakanyanya uye asingashandise simba zvakanyanya kunobva paTMA yakachena kwazvo.
* LED Epitaxy: Inoshanda searuminiyamu inotangira muMOVPE reactors kuti ikure ma layers anoshanda (semuenzaniso, AlGaN) mubhuruu, girini, uye ultraviolet LEDs.
* Kuisa Mudziyo Pasi: Inoshandiswa kuisa mafirimu ekudzivirira aruminiyamu oxide kana aruminiyamu nitride anowedzera kushanda zvakanaka kwekubvisa optical uye kuwedzera hupenyu hwekushanda kwemidziyo yeLED.
4. Kugadzira Maindasitiri nePolymer
Kukosha kweTMA mumaindasitiri kwakavakirwa pabasa rayo mukugadzira zvinhu zvitsva.
* Polyolefin Catalysis: Ndiyo chinhu chikuru chinotangira kugadzirwa kweMethylaluminoxane (MAO), chinhu chakakosha muZiegler-Natta uye metallocene catalyst systems. Aya masystem anogadzira ruzhinji rwemapurasitiki epolyethylene nepolypropylene pasi rose.
Hunhu Hukuru & Mabhenefiti:
* Kuchena Kwakanyanya: Kunodzorwa zvakanyatsonaka kuderedza kusvibiswa kunokanganisa mashandiro emagetsi uye basa rekugadzirisa zvinhu.
* Superior Precursor: Inopa kugadzikana kwakanaka, kugadzikana kwekupisa, uye hunhu hwakachena hwekuora kwefirimu kuti ifukidzwe zvakanaka.
* Standard yeIndasitiri: Sosi yealuminium yakasimbiswa uye yakavimbika yeMOVPE, ALD, uye CVD maitiro muR&D yepasi rose nenzvimbo dzekugadzira.
* Nheyo yeMapurasitiki: Chinhu chakakosha chinogonesa kugadzirwa kwemapolyolefin polymers anoshanda zvakasiyana-siyana uye akakosha.
Chiziviso: Trimethylaluminium chinhu chinonyorova uye chinodzivirira hunyoro chinoda nzira dzakagadzirwa dzekugadzirisa nekuchengetedzeka. Ruzivo rwunopihwa nderwekutsanangura. Ibasa remushandisi kubata chinhu ichi zvichienderana nemirairo yese yekuchengetedza inoshanda uye kuona kuti chakakodzera here kushandiswa kwacho.
