CMOS IC are fabricated on thin circular slices
of silicon called wafers.
Wafer fabrication operations : surfacecleaning, epitaxy, thermal oxidation,
diffusion, ion implantation, lithography,
etching, CVD, Metal deposition, Metalsintering, Backgrinding, multiprobing

MOSIS (Metal Oxide Semiconductor Implementation
Service) MOSIS dioperasikan oleh Information Sciences Institute di
University of Southern California (USC) MOSIS didirikan sejak tahun 1981 dan merupakan lembaga
pertama di dunia yang memberikan layanan untuk
memproduksi IC
MOSIS menggabungkan beberapa desain IC yang diajukanoleh konsumen baik perusahaan maupun universitas menjadimulti-project wafers (MPW) sehingga akhirnya parakonsumen dapat berbagi ongkos pembuatannya.
Dalam pelayanannya, MOSIS menggunakan internet yaitu
dalam format email atau FTP.

LASILASI (LAyout System for Individuals) is a "general
purpose" layout and design system originally
intended for integrated circuits. It is versatileenough that it can be used for ICs, MEMS, othernanotechnologies, discrete devices, schematics,PC boards and project documentation drawings.
LASI is a "precision" drawing system wherefigures are always precisely located. LASI isintended for both educational and professionaluse.

Based on the book, which explain:
Getting started, help, navigation, drawing a box,
moving and resizing, drawing grids, makingmeasurements, key assignment, cells in LASI,moving a cell, viewing or editing specific layer, thepolygon and path shapes, using text in lasi, some
feature to speed up layout design, understandingthe Cpy and copy command, transporting cells inLASI, Edit in place, backing up the works
