No ka mea kākau ke kuleana kope.E ʻoluʻolu e kelepona i ka mea kākau no ka ʻae ʻia no ka paʻi hou ʻana i nā pāʻoihana, a e haʻi mai i ke kumu no nā paʻi hou ʻole.

No ke aha e pono ai nā uea i nā ʻili plastik?ʻAʻole hiki iā ʻoe ke hoʻohana i ka uea keleawe ʻole?No ka mea, me ka ʻole o ka ʻili plastik e hoʻokaʻawale iā lākou, hiki i ka uea ke hoʻokele i ka uila ke hoʻopā ʻo ia i nā mea ʻē aʻe a ʻaʻole hiki ke hoʻokuʻu i ke au, a i ʻole inā he ikaika a hoʻoheheʻe i kekahi?Pehea inā pono e hana ʻia nā uwea non-conductive hou me ka plastic?ʻAʻole loa, ua uhi nā uea mua i ka lole olonā, ka ʻaila tung (a i kēia manawa, enameled wire), ma nā wahi kikoʻī, me ka noʻonoʻo ʻana i ke kumukūʻai, ka hiki ke hoʻokaʻawale i ka uila, a me nā mea ʻē aʻe, a inā makemake ʻoe, hiki iā ʻoe ke hoʻohana i ka silicon , silicon dioxide e hana kaʻawale, ʻoiaʻiʻo, ʻo kēia mau mea ʻelua he mea paʻa paʻa loa, kūpono wale no kahi uea i hana ʻia, ʻaʻole loa e pili ana i ke kelepona, ʻo ia ka mea kūpono no ka chip uea kūloko i kēia hiʻohiʻona.

Hiki i ka mea i luna me ka silika a me ka silicon dioxide no ka hoʻokaʻawale uea no nā ʻāpana.ʻAe, ʻo kekahi o ka hoʻohana nui ʻana o nā substrates silicon i nā chips no ka hoʻokaʻawale ʻana, e like me ka hoʻohana ʻana i nā ʻili plastik no nā uea, i hana ʻia i ka huli ʻana.Loaʻa nā uea keleawe ʻole ma mua o ka pena ʻia ʻana me nā ʻili plastik;Loaʻa i nā chips nā ʻili hoʻokaʻawale silika ma mua o ka waiho ʻia ʻana (ka uhi ʻia) me nā uea keleawe ʻole.

No ke aha lā hoʻokahi kilikakilika?ʻElua kumu, ʻo ka mea mua, pono ia e maʻemaʻe loa, inā ʻaʻole ia e hoʻokaʻawale ʻia ma muli o ka conductivity o ka mea komo a ʻaʻole e hāʻawi i kahi kikoʻī pre-material no ka hanauna hope o ka hui semiconductor.Maikaʻi loa kēia, ʻaʻole anei?Makemake ʻoe e hana i kahi junction PN ma kekahi wahi, akā aia kekahi mau ʻāpana phosphorus atom ma kēlā wahi a he ʻano ʻano N ia, no laila makemake ʻoe e hoʻololi iā ia i kahi ʻano P?He mea maʻalahi ka hele ʻana mai ka maʻemaʻe a i ka heterogeneous, akā paʻakikī loa ka hele ʻana mai ka heterogeneous a i ka maʻemaʻe, no laila e hoʻomaka ʻoe me ka silika maʻemaʻe kiʻekiʻe.No ke aha ʻaʻole hiki ke lilo i silika polycrystalline?E pili ana ia i ka hanauna o nā hui PN (he mau hoʻolālā ʻē aʻe paha, i hōʻike ʻia e PN).ʻO kēia no ka mea liʻiliʻi loa nā junctions PN no ke kaʻina intercalation a me nā hiʻohiʻona kaapuni hopena, e koi ana i ka 100% e hoʻokō me nā koi hoʻolālā, e hōʻoia pololei ʻia inā ʻaʻohe hemahema lattice, ehia mau "mea haumia" i hui pū ʻia, a he aha ka uila. loaʻa nā hiʻohiʻona.

Inā loaʻa nā hemahema lattice, ʻaʻole pono kēia.ʻO nā hemahema lattice i loko o ka polysilicon e like me nā lua i loko o ke kumu, a nui loa lākou, no laila ke waiho ʻia ka asphalt, ʻaʻole like ka pane uila me nā wahi ʻē aʻe.Lilo ia 1!Ua pololei anei keia manao kaapuni?Ma ka hoʻonui, hiki ke hoʻohana ʻia nā mea ʻē aʻe?Hiki ke hoʻohana ʻia ka polycrystalline?Ma nā noi ʻē aʻe, a i ʻole kahi maʻalahi ʻole (ka mana ikaika, ka loiloi ʻole nāwaliwali), hiki ke noiʻi ʻia.No ka laʻana, ʻo ka silika ka doped loa i kekahi mau ultra-high frequency, ultra-low voltage, ultra-high current situations, ʻaʻole kūpono loa, a laila aia kekahi mau silicon germanium kūikawā, gallium a me nā mea ʻē aʻe o ka kuhikuhi, a me ka substrate o ʻO ka puʻupuʻu, nā panela lā no ka mea ʻo ka mea nui ka hāʻawi ʻana i ka uila ikaika, ʻaʻole hopohopo e pili ana i ka ʻokoʻa uila no ka liʻiliʻi, ʻoiaʻiʻo, aia ke kumukūʻai, ʻo ka hapa nui o lākou he polycrystalline silicon.No nā mea ʻē aʻe, ma hope o nā mea a pau, aia ka silicon ma nā wahi āpau a pono e hoʻomaʻemaʻe wale ʻia.ʻO nā mea ʻē aʻe, he paʻakikī ke loaʻa, pono e hoʻomaʻemaʻe pū kekahi.
