Kazhinji kutaura, zvakaoma kudzivirira kutadza kudiki mukuvandudza, kugadzira uye kushandiswa kwesemiconductor zvishandiso.Nekuenderera mberi kwekuvandudzwa kwezvinodiwa zvemhando yechigadzirwa, kuongororwa kwekutadza kuri kuwedzera kukosha.Nekuongorora machipisi chaiwo ekutadza, Inogona kubatsira vagadziri vedunhu kuwana kukanganisa kwedhizaini yedhizaini, kusawirirana kwemaparamita ekuita, dhizaini isinganzwisisike yedunhu redunhu kana misoperation inokonzerwa nedambudziko.Iko kudikanwa kwekutadza kuongororwa kwesemiconductor zvishandiso kunonyanya kuratidzwa mune zvinotevera zvinhu:
(1) Kutadza kuongororwa inzira inodiwa yekuona kukundikana kwechigadzirwa chip;
(2) Kutadza kuongororwa kunopa hwaro hunodiwa uye ruzivo rwekuongororwa kunoshanda kwemhosho;
(3) Kutadza kuongororwa kunopa ruzivo rwakakosha rwemhinduro kune vanogadzira mainjiniya kuti varambe vachivandudza kana kugadzirisa iyo chip dhizaini uye kuita kuti ive inonzwisisika zvinoenderana neyakagadzirirwa dhizaini;
(4) Kutadza ongororo inogona kupa inodiwa yekuwedzera bvunzo yekugadzira uye inopa inodiwa ruzivo hwaro hwekuita optimization yekuongorora bvunzo maitiro.
Nekutadza kuongororwa kwema semiconductor diodes, audions kana maseketi akasanganiswa, magetsi paramita anofanirwa kuongororwa kutanga, uye mushure mekuonekwa kwekutarisa pasi pe optical microscope, kurongedza kunofanira kubviswa.Nepo kuchengetedza kutendeseka kweiyo chip basa, iyo yemukati nekunze inotungamira, mapoinzi ekubatanidza uye pamusoro peiyo chip inofanira kuchengetwa zvakanyanya sezvinobvira, kuitira kugadzirira danho rinotevera rekuongorora.
Kushandisa scanning electron microscopy uye simba spectrum kuita ongororo iyi: kusanganisira kucherechedzwa kweiyo microscopic morphology, kukundikana kwekutsvaga nzvimbo, kuremara nzvimbo yekutarisa nenzvimbo, kuyerwa kwakaringana kwesaizi yeiyo microscopic geometry saizi uye hutsinye hwekugona kugovera uye kutonga zvine musoro kwegedhi redhijitari. dunhu (ine voltage musiyano mufananidzo nzira);Shandisa simba spectrometer kana spectrometer kuita ongororo iyi ine: microscopic element composition analysis, material structure kana kusvibisa ongororo.
01. Kuremara kwepamusoro uye kutsva kwemidziyo yesemiconductor
Kuremara kwepamusoro uye kupisa-kunze kwemidziyo yesemiconductor ese ari maviri akajairwa maitiro ekutadza, sezvakaratidzwa muMufananidzo 1, inova kukanganisa kweiyo yakanatswa layer yedunhu rakasanganiswa.
Mufananidzo 2 unoratidza kukanganisa kwepamusoro kwesimbi yakanyungudutswa yedunhu rakasanganiswa.
Mufananidzo 3 unoratidza nzira yekuputsika pakati pemarata maviri esimbi edunhu rakasanganiswa.
Mufananidzo 4 unoratidza simbi strip kudonha uye skew deformation pamhepo zambuko mune microwave mudziyo.
Mufananidzo 5 unoratidza kutsva kwegridi kweiyo microwave chubhu.
Mufananidzo 6 unoratidza kukuvadzwa kwemichina kune yakasanganiswa yemagetsi metallized waya.
Mufananidzo 7 unoratidza mesa diode chip kuvhura uye kukanganisa.
Mufananidzo 8 unoratidza kuparara kwe diode yekudzivirira pakupinza kwedunhu rakabatanidzwa.
Mufananidzo 9 unoratidza kuti pamusoro peiyo yakabatanidzwa yedunhu chip inokuvadzwa ne mechanical impact.
Mufananidzo 10 unoratidza kutsva kwechidimbu kweiyo yakabatanidzwa yedunhu chip.
Mufananidzo 11 unoratidza diode chip yakaputsika uye yakapiswa zvakanyanya, uye nzvimbo dzekuputsika dzakashanduka kuita kunyungudika.
Mufananidzo 12 unoratidza gallium nitride microwave power chubhu chip yakapiswa, uye nzvimbo yakatsva inopa yakanyungudutswa sputtering state.
02. Electrostatic breakdown
Semiconductor zvishandiso kubva mukugadzira, kurongedza, zvekufambisa kusvika pane redunhu bhodhi rekuisirwa, welding, kugadzira muchina uye mamwe maitiro ari pasi pekutyisidzirwa kwemagetsi static.Mukuita uku, chekufambisa chinokuvadzwa nekuda kwekufamba nguva zhinji uye kuratidzwa nyore kune static magetsi anogadzirwa nenyika yekunze.Naizvozvo, kutarisisa kwakanyanya kunofanirwa kubhadharwa kune electrostatic kuchengetedza panguva yekufambisa uye yekufambisa kuderedza kurasikirwa.
Mune semiconductor zvishandiso zvine unipolar MOS chubhu uye MOS yakabatanidzwa yedunhu inonyanya kutarisisa magetsi akamira, kunyanya MOS chubhu, nekuda kwekupokana kwayo kwakakwira zvakanyanya, uye gedhi-source electrode capacitance idiki kwazvo, saka zviri nyore kwazvo kuva. yakakanganiswa nekunze kwemagetsi emagetsi munda kana electrostatic induction uye kuchaja, uye nekuda kweiyo electrostatic chizvarwa, zvinonetsa kuburitsa kuchaja nenguva, Naizvozvo, zviri nyore kukonzera kuunganidzwa kwemagetsi static kusvika nekuparara kwechishandiso.Chimiro chekuparara kwe electrostatic inonyanya kuparara kwemagetsi, kureva kuti, iyo yakatetepa oxide layer yegridi yakaputsika, ichiita pinhole, iyo inopfupisa mukaha pakati pegridi nekwakabva kana pakati pegridi nedhiraini.
Uye hukama neMOS chubhu MOS yakabatanidzwa yedunhu antistatic kuparara kugona kuri nani zvishoma, nekuti yekuisa terminal yeMOS yakabatanidzwa wedunhu ine inodzivirira diode.Pakangoita hombe yemagetsi emagetsi kana surge voltage mukati meakawanda edziviriro diode anogona kuchinjirwa pasi, asi kana voltage yakawandisa kana yekukurumidza amplification ikozvino yakakura, dzimwe nguva madhiodhi ekudzivirira anozviita iwo ega, sezvakaratidzwa mumufananidzo. 8.
Mifananidzo yakati wandei inoratidzwa mumufananidzo13 ndiyo electrostatic breakdown topography yeMOS yakabatanidzwa dunhu.Iyo nzvimbo yekuputsika idiki uye yakadzika, ichiratidzira yakanyungudutswa sputtering state.
Mufananidzo 14 unoratidza kutaridzika kwekuparara kwemagetsi emusoro wekombuta hard disk.
