Characteristics
- Introduction
- Variation
- Manufacturing
ICROS™ TAPE is a surface protective tape used in silicon wafer back-grinding process for the manufacturer of integrated circuits.
- Two US patents (4853286 & 4928438)
- Japan Patent (1563284)
- Korea Patent (34757)
- Mitsui Chemicals offers solutions for every backgrinding application:
- Conventional Tapes
Non-UV
UV - Bumped Wafer Tapes
Gold bump (20-30um bump height)
Pillar Bump (40-100um bump height)
Solder Bump (100-150um bump height)
Solder bump (150um+ bump height) - Thin Grinding Tapes
- Chemical Resistant / Heat Resistant Tape
ICROS Tape can be processed using a "no rinse" process, which is shorter than conventional processing methods resulting in lower production costs and minimum wafer breakage
NO RINSE PROCESS customers : OVER 40 in the world
[ For thin wafer grinding : No Rinse process ]
The consistency in its wafer thickness after back grinding and minimal wafer breakage are only two of the attributes that contribute to its reputation and reliability.

ICROS™ Conventional Tapes (Non-UV and UV Types)
Conventional Tapes - Non-UV Type
The non-UV conventional type of the ICROS™ backgrinding wafer tape line features little to no contamination transferred to the wafer surface, outstanding topography absorption, prevents water penetration and wafer breakage, and superior TTV.
- Superior TTV
- Soft & Hard Type
- Multiple thickness types
- No residue after removal
- Low ionic impurities
- Easy detaping
- Many adhesive types and strengths
Conventional Tapes - UV Type
The UV tape of the ICROS backgrinding wafer tape line features high adhesive strength, no contamination transferred to the wafer surface, outstanding topography absorption, prevents water penetration and wafer breakage, and superior TTV.
- Superior TTV

- Superior TTV
- Soft intermediate layer provides for good bump absorption
- Low ionic impurities
- Low adhesive strength after UV irradiation makes detaping easy
Solder Bumped Wafer Tape for 150+um Bump Height
The ICROS™ bumped wafer tape is the best solution for super high bumped wafers such as solder bump. It features a special resin middle layer for good bump absorption. Thin adhesive layer to prevent water penetration and wafer breakage.
- Superior TTV
- Special resin layer transforms to bump shape providing good bump absorption
- Low ionic impurities
- Both Non-UV and UV types adhesive available
ICROS™ Thin Grinding Tapes
The ICROS™ thin wafer backgrinding tape line features special anti-warpage properties that significantly flattens the wafer. This tape has a warpage of 2mm versus 26mm for conventional tape which reduces risk of wafer breakage during handling and transportation. In addition, the super clean adhesive is designed to eliminate the rinse process.
- Superior TTV
- Hard type base film to support extra thin wafers
- Anti-warpage properties
- No residue after removal
- High temperature capable
- Easy detaping
- Low Taping Tension to Reduce Wafer Warpage
