Overview

Note: the following is quoted from ULTRA TEC's documentation

General Description

ASAP-1® IPS is a digital sample preparation system for the decapsulation, thinning and polish­ing of packaged wafer-level devices.

Drawing on ULTRA TEC’s market knowledge and long-standing leadership in electronic sample preparation, IPS is ‘device centric’ – designed to meet the non-destructive, high yield and survivability needs of micro-electronic components.

IPS’ Touch Screen OS has been designed from the ground-up to control all aspects of the sample preparation process. Advanced programming drives IPS’s deep sub-micron axes of motion. The machine vision monitor provides an unique ‘always-live’ image of the device, along with key navigational and process information.

The touch-off tool control provides Z-position at pre-defined locations and pressures – enabling package and die tilt to be corrected quickly and accurately. Tool height variations are automatically-calibrated.

Selected area preparation

"Selected Area Preparation (SAP) has long been established as a low damage machining method, with the use of relatively low spindle speeds, in conjunction with the floating head providing very low temperature rises. This is in stark contrast with high speed 'mills' which introduce excess vibration, ultrasonics, and process temperature rises -- generally requiring either a cooling bath to be in position at all time, or even a constant high flow of coolant to avoid device overheating. SAP is almost always a ‘wet process’ . However the coolant required is minimal."

The use of ULTRA TEC’s patented 'float down' head approach has enabled several hundred customers to achieve high quality polished surfaces, ready for analysis. High yields have been shown using analog ASAP-1® equipment for thinning silicon to less than 20 micron target RST. The move to higher accuracy digital systems allows for routine thinning of extremely thin substrates at even low single-digit RST’s. The move to larger flip chips mounted on PCB substrates requires inherent design for 3D sample prep. Sample Preparation developments have been driven by the industry's push for both smaller RST’s – for optimal backside imaging and attenuation – and the need for improved uniformity, to satisfy the latest analytical techniques.

Sample Requirements and Preparation

The Automated Selected Area Polisher (ASAP-1-IPS) is designed to thin and polish small selected areas (windows) in electronic packages and wafer-level dies. The resultant thinned component is transparent to infra-red light, thus enabling backside failure analysis to be carried out on the (front side) circuitry in the device.

Sample mounting

Your sample needs to be mounted flat and rigid to the sample holder.  Assuming mounting technique meets these two criteria, there is no preferred method.  Below are a couple common mounting techniques used regularly.

  1. Bond small samples to glass slide using Crystal Bond 555-HMP, then use clamps to hold slide in place.
    1. Place glass slide on hot plate and heat to 80 degrees C.
    2. Spread a small amount of Crystal Bond 555-HMP over the area where sample will be mounted.
    3. Press sample firmly down onto Crystal Bond and allow assembly to cool to room temperature.
    4. Place assembly onto sample holder and use mechanical clamps to hold the glass slide in place.
  2. Bond sample directly to the sample holder using Crystal Bond 555-HMP.
    1. Remove the sample holder from the ASAP-1 tool.
    2. Place on hot plate and heat to 80 degrees C.
    3. Spread a small amount of Crystal Bond 555-HMP over the area where sample will be mounted.
    4. Press sample firmly down onto Crystal Bond and allow assembly to cool to room temperature.
    5. Mount sample holder back onto the ASAP-1 tool.
  3. Mechanical Clamps
    1. Using the threaded holes provided in the sample holder, mount clamps in place as needed.  Two options on each side, one closer to the middle, the second further away from center accomodating a wide range of sample widths.
    2. The screw that threads into the clamp is used to adjust the clamp for your sample thickness.  That screw needs to be adjusted so that it sticks our futher than the sample is thick resulting the the front edge of the clamp making contact with the sample.
    3. Tighten the slotted screw until firm.
      1. Be sure to adjust the rear screw on the clamp appropriately based on the sample thickness.  You need to have the edge exerting force on the sample top, not exerting clamping force on the glass slide / sample edge.

        _Proper contact angle in this image is exagerated for illustrative purposes.


      2. Be careful not to exert too much force on the sample.  Clamping introduces stress on the package/wafer that can result in cracking or warping during the thinning process.

    Step 10 - Start the spindle (2000 RPM recommended)

    • From the Keypad screen, click , enter desired rotational speed into
      the field, then click . The spindle will begin rotating at the
      set speed.

    Step 13 11 - Begin the thinning process

    • Navigate to the Run screen
    • You should see your entered timer value in the Timer section
      under Set(Sec).
    • Make sure the Timer box is checked, indicating the tool should stop when
      the Elapsed time equals Set time.
    • Click and the tool will start rastering across the selected
      area.
    • Click to navigate to the Keypad Screen.
    • Click , enter desired depth into field as a negative value,
      then click
      . It is recomended recommended to remove a maximum of 50 μm
      per processing step.
    • While continuing to raster, the head will slowly move down onto the part
      until the
      set polishing force is reached. Initially, the tool will try to maintian
      this set force by moving down in Z. Once Z has reached set point, the
      tool will hold Z position and continue processing while the applied force
      fades to zero.
    • The process will stop automatically and position the tool at the end point
      with Z ~50 μm above final Z depth when the set time has past.


    Step 14 12 - Continuing to thin the sample

    • Since our extender fluid will become saturated with ground material,
      if you need to thin your sample by more than 50 μm, you should do so in
      multiple steps.
    • From the Keypad screen click , enter 20 into field,
      then click
      . The head should lift 20 μm off the sample and
      force should read ~0.
    • Use your hand to gently lift the head to the top of travel. Engage the
      locking handle by rotating the handle clockwise until tight. Make sure
      the head is locked before removing the support of your hand.
    • Wipe up the used extender fluid using a clean wipe and isopropyl
      alcohol.
    • Apply another drop or two of fresh extender fluid.
    • Gently lower the head into operating position.

      • Be careful, if you release the locking mechanism and allow the
        polishing head to drop onto the force
        sensor, damage to the tool
        will occur.
    • Return to Step 1110 above and continue. Repeat steps 10 through 14 12 until
      the desired thinning has been achieved.
