List of Steps
This is a list of processing techniques that are employed numerous times in a modern electronic device and do not necessarily imply a specific order.
- Wafer processing
- Wet cleans
- Photolithography
- Ion implantation (in which dopants are embedded in the wafer creating regions of increased (or decreased) conductivity)
- Dry etching
- Wet etching
- Plasma ashing
- Thermal treatments
- Rapid thermal anneal
- Furnace anneals
- Thermal oxidation
- Chemical vapor deposition (CVD)
- Physical vapor deposition (PVD)
- Molecular beam epitaxy (MBE)
- Electrochemical deposition (ECD). See Electroplating
- Chemical-mechanical planarization (CMP)
- Wafer testing (where the electrical performance is verified)
- Wafer backgrinding (to reduce the thickness of the wafer so the resulting chip can be put into a thin device like a smartcard or PCMCIA card.)
- Die preparation
- Wafer mounting
- Die cutting
- IC packaging
- Die attachment
- IC bonding
- Wire bonding
- Thermosonic bonding
- Flip chip
- Wafer bonding
- Tab bonding
- IC encapsulation
- Baking
- Plating
- Lasermarking
- Trim and form
- IC testing

Famous quotes containing the words list of, list and/or steps:
“Feminism is an entire world view or gestalt, not just a laundry list of womens issues.”
—Charlotte Bunch (b. 1944)
“Do your children view themselves as successes or failures? Are they being encouraged to be inquisitive or passive? Are they afraid to challenge authority and to question assumptions? Do they feel comfortable adapting to change? Are they easily discouraged if they cannot arrive at a solution to a problem? The answers to those questions will give you a better appraisal of their education than any list of courses, grades, or test scores.”
—Lawrence Kutner (20th century)
“I stand on top
of our back steps and breathe the rich air
a mother skunk with her column of kittens swills the garbage pail.
She jabs her wedge-head in a cup
of sour cream, drops her ostrich tail,
and will not scare.”
—Robert Lowell (19171977)
