Used Logitech DH-300

Inventory Number: 64136
Now (USD): $19,000.00

Logitech DH-300 Driven Head Precision Polishing System. Developed to address the issue of polishing times when processing semiconductor materials often describe as “hard” to polish within the industry. These systems have been designed for semi-automated final stage polishing of hard materials such as sapphire, silicon carbide (SiC)or gallium nitride (GaN). Features special polishing carrier head that applies high levels of down-force onto the samples, whilst rotational speed and direction are fully controllable. This results in the highest level of sample throughput of any of the Logitech systems.

  • Manual Mode’ allows operators to control individual process parameters and variables such as rotational speed and direction of carrier heads via the Graphical User Interface (GUI).
  • ‘Automatic Mode’ allows users to save and re-call multi-stage process recipes – making each process completely repeatable, even across different operators.

Used Sweco DM01L

Inventory Number: 64218
Now (USD): $3,500.00

SWECO DM01L Vibro-Energy Grinding Mill. SWECO Vibro-Energy Grinding Mills are the most versatile line of mills available today for fast, low-cost particle size reduction to sub-micron range. Vibro-Energy grinding action achieves higher output per input horsepower; precise control of size and distribution. Product contamination from media and lining wear is virtually eliminated. Maintenance costs are low because of few moving parts and replaceable linings made of abrasion-resistant metal, ceramic or elastomers.
The SWECO Vibro-Energy Mill's unique vibratory motion, coupled with the use of cylindrical media, allows a dense packing of the media bed assuring maximum media surface contact and minimum void area when operated under a low energy condition. Feed materials as large as 300 microns can be reduced to sub-micron sizes. Bowl OD 23 3/4" and depth is 8". 440V,3Ph, 60Hz, 6A

Used Semiconductor Equipment Corporation 3250

Inventory Number: 64254
Now (USD): $5,950.00

Semiconductor Equipment Corp 3250 Wafer Backlap Applicator.

Semiconductor Equipment Corporation´s Model 3250 applies Protective Tape to Your Wafer Prior to Backlapping. The applicator also:
  • Eliminates bubbles between tape and wafer
  • Provides uniform tension between tape and wafer
  • Operates with backed and non-backed tape
  • Provides adjustable roller pressure
  • Cuts tape within .005 ” of edge of wafer

FEATURES

 
  • Four, five, six and eight inch wafer capability standard.
  • Trims tape to the edge of the wafer including the flats, within .005 “.
  • Manual tape feed.
  • Manual tape tensioner.
  • Compatible with standard or interleaved tape.
  • Vacuum stage wafer hold-down.
  • Built in cutter tape separation systems.
  • Captive roller assembly assures consistent wafer/film frame contact pressure.
  • Adjustable spring loaded platen for optimum contact pressure.

Includes the optional Items:

  • Heated Blade Assembly. Heats cutting blade to reduce friction when cutting particular types of back lapping tapes. Heats to 75 degrees C.
  • Motorized Take-up System to gather the liner from dicing tape onto a disposable core. Many semiconductor dicing tapes have a protective liner, which has to be gathered and disposed of. This option makes that process effortless and convenient.
