   The MOSIS SCMOS technology file in this directory is obtained at the
   time of the release.  It is included here for the purpose of
   illustration only.  To use it for your actual design work, you are
   advised to obtain the latest MOSIS technology file(s) directly from
   MOSIS at mosis@mosis.edu.

INTRODUCTION

  This officail MOSIS SCMOS technology release consists a famaly of
  SCMOS technology files for Magic version 6.3 (available from
  anonymous FTP gatekeeper.dec.com):

   * "scmos"     - standard SCMOS technology for MOSIS process with
	           minimum feature length larger than 1.5 micron.
   * "scmos-hp"  - SCMOS technology for MOSIS HP CMOS processes.
		   Both HPCMOS34 and CMOS26b processes are supported.
   * "scmos-ibm" - SCMOS technology for MOSIS HP CMOS processes.
		   Specifically, IBM CMSX-2185 process.

  To invoke Magic with appropriate technology selection, you need to
  use the '-T' command option. For example, the command

     "magic -Tscmos-ibm"

  start Magic with "scmos-ibm" designated for IBM process.

  MOSIS's distribution of Magic technolofy file for SCMOS technology
  now has CIFinput and CIFoutput section in templates so that it will
  be easier to maintain. It also supports two layers, "open" and
  "pstop" for micro-machined design fabrication in CMOS process as 
  described by Janet C. Marshall's paper in IEEE Circuit and Devices,
  Vol. 8, N0. 6, 1992. this layer is now in a 'preliminary' stage.
 
  Before installation, please read the file 'COPYRIGHT' for copyright
  notice.

INSTALLATION

  *** NOTE:  Magic 6.4 already has these patches installed, including
      the MAXPLANES patch. 

  First, you'll have to have the vanilla version 6.3 source code
  patched with the following notes (available from FTP):

    Magic note.1 - 9/14/90 - ANNOUNCEMENT:  Magic V6 is ready 
    Magic note.2 - 9/19/90 - DOC:  Doc changes (fixed in releases
	after 9/20/90)
    Magic note.3 - 9/19/90 - GRAPHICS:  Mode problem (fixed 9/20/90)
    Magic note.4 - 9/19/90 - HPUX:  rindex macro for HPUX 7.0 and
	later
    Magic note.5 - 9/19/90 - GCC:  "gcc" with magic, one user's
	experience
    Magic note.6 - 9/19/90 - FTP:  Public FTP area for Magic notes
    Magic note.7 - 9/20/90 - RSIM:  Compiling rsim, one user's
	suggestions & hints
    Magic note.8 - 9/26/90 - GENERAL:  Magic tries to open bogus
	directories
    Magic note.9 - 9/26/90 - GRAPHICS:  Mods to X11Helper 
    Magic note.10 - 10/5/90 - DOS:  Magic V4 for DOS and OS/2
    Magic note.11 - 10/11/90 - GENERAL:  reducing memory usage by 600k
    Magic note.12 - 12/19/90 - EXT2xxx:  fixes bogus resistances
    Magic note.13 - 12/19/90 - EXTRESIS:  fixed bug in resis that
	caused coredump.
    Magic note.14 - 12/19/90 - EXTRESIS:  new version of scmos.tech
	for extresis
    Magic note.15 - 12/19/90 - TECH:  documentation for contact line
	in tech file 
    Magic note.16 - 12/19/90 - EXTRACT:  bug fix to transistor
	attributes
    Magic note.17 - 5/13/91 - CALMA:  Incorrect arrays in calma output
    Magic note.18 - 5/14/91 - CALMA:  Extension to calma input
    Magic note.19 - 6/28/91 - IRSIM:  Some .prm files for IRSIM
    Magic note.20 - 7/18/91 - EXTRESIS:  fixes for Magic's extresis
	command
    Magic note.21 - 11/4/91 - FAQ:  Frequently asked questions 
    Magic note.22 - 11/6/91 - CALMA:  how to write a calma tape
    Magic note.23 - 11/4/91 - EXT2xxx:  fix for incorrect resistor
	extraction
    Magic note.24 - 11/8/91 - EXTRESIS:  fix 0-ohm resistors 
    Magic note.25 - 11/15/91 - NEXT:  porting magic to the NeXT machine
    Magic note.26 - 11/21/91 - IRSIM:  fix for hanging :decay command
    Magic note.27 - 12/17/91 - RESIS:  fix for "Attempt to remove node
	..." error

  This *very* important, especially for note 17, 18, 22!

  This latest updae requires the maximum number, i.e. 96, layers of
  tile. You'll have to change the following line in the "database.h"
  file under ~src/magic/database directory:

#define MAXPLANES       20      /* Maximum number of planes per cell */
#define TT_MAXTYPES     96      /* See above!*/

  and recompile Magic in order to be able to read this version without
  error.

  If you have Magic version 6.4 installed, then you don't have to go
  through all steps mentioned above.

  To generate all technology files, simply type

     "make" if your are using Magic 6.4, or

     "make version3" if your are using Magic 6.3.

  To install all technology files into the standard ~cad library, just type

     "make install"

  to you system (Unix) prompt. You might want to check the path for
  standard ~cad/lib/magic/lib first before you do this...

IRSIM PARAMETERS

  Parameter files of various MOSIS supported process  for IRSIM
  switch-level simulator can be found under the sub-directory
  "irsim_parameters".

DOCUMENTATION

  In the doc subdirectory, you can find a preliminary PostScript file
  for MOSIS's SCMOS Technology Manual. Warning: This manualscript is
  in a very preliminary stage, if you have any problem with it don't
  hesitate to discuss it further with me...(pi@isi.edu)

EXAMPLE

  In the 'examples' subdirectory, we have:

  palette.mag - palette of all layers available in MOSIS's SCMOS tech-
	nology". Turn your DRC off before viewing it!!

  ccd.mag - An example of a buried channel CCD layout.

  float_gate.mag - An example of a floating-gate device.

  wellcap.mag - An example of layout of linear capacitors available
	from SCNLC technology, i.e. HP's 1.2um process.

  npn.mag - An example of a Bipolar NPN transistor layout. For ORBIT's
	2um lower-noise Analog process.

  large_npn.mag - A large NPN bipolar transistor consists of smalls
	unit transistors.

  all.mag - An example of part of the design rules... NOT Complete...

  m3padframe.mag - A TinyChip padframe for HP's 1.0um process. Notice
	that those m1 strip is required to complete a DRC free pad.
	These pads use all three metal layers.

  inf_source - An example of micromachined device fabrication. This
        layout is a reproduction of Fig. 8 of Janet C. Marshall's
	article titled "High Level Melds Micromachined Devices with
	Foundries", IEEE Circuits and Devices, Vol. 8, No. 6, pp.
	10-17, Nov. 1992. A complete NIST MEMS library is also
        available from MOSIS's anonymous FTP archive.
