APAKAH MAKSUD PHOTOLITHOGRAPHY dalam CORSICA?
Fotolitografi
Fotolitografi, juga dikenali sebagai litografi optik atau litografi UV, merupakan proses yang digunakan dalam pembekuan microfabrication kepada bahagian-bahagian corak filem tipis atau sebahagian besar substrat. Ia menggunakan cahaya untuk memindahkan corak geometri dari fotomask kepada fotoresist kimia yang sensitif cahaya, atau hanya "menahan," pada substrat. Satu siri rawatan kimia sama ada mengukir corak pendedahan ke dalam, atau membolehkan pemendapan bahan baru dalam corak yang diingini, bahan di bawah foto itu menentang. Sebagai contoh, dalam litar bersepadu yang kompleks, wafer CMOS moden akan melalui kitaran fotolithografik sehingga 50 kali. Photolithography berkongsi beberapa prinsip asas dengan fotografi dalam corak dalam menentang etsa dibuat dengan mendedahkannya kepada cahaya, sama ada secara langsung atau dengan imej yang diunjurkan menggunakan topeng optik. Prosedur ini adalah sebanding dengan versi ketepatan tinggi kaedah yang digunakan untuk membuat papan litar bercetak. Peringkat seterusnya dalam proses ini mempunyai lebih banyak kesamaan dengan etsa daripada dengan percetakan litografi.
