3D Capability The X-PrepŽ 3D is useful for package deprocessing and die thinning for electrical fault localization methods that demand extreme uniformity of material removal and final thickness control. This capability is ideal for warped substrates that feature either convex or concave geometry. The advantage of deprocessing a device following its physical profile is that it remains in its “asmanufactured� physical state. This approach increases accuracy of material removal and reduces the risk of either mechanically induced or post-processing stress relaxation damage such as cracking and/or delamination. The functionality includes the capability to use and/or create custom/predictive maps to control the milling profile. Both symmetrical and asymmetrical profiles can be used and adjusted to match the physical changes encountered, providing a high degree of versatility to the operator.

Flat-plane deprocessing (left) produces nonuniform material removal and thickness. Deprocessing the device by following its profile (right) ensures uniform material removal.


3D Capability – Concave – Package Level

In Support of… • Package-level failure analysis • TDR, GMR/SQUID & Lock-In Thermography (LIT) As packaging technology continues to advance, the physical profile and shrinking density render the use of flat-plane sample preparation tools obsolete due to nonuniform deprocessing. The X-Prep® 3D overcomes these challenges and enables uniform deprocessing of all device types. Leading-edge technology and advanced components utilizing a closed-loop control system ensure unmatched accuracy and precision.

Uniform FR4 substrate delayering

• Stacked die deprocessing – X-ray image before (top) and after (bottom) • 8-layer die stack deprocessed to die 7 Uniform copper (Cu) pillar • 4-layer board deprocessed to layer 1 deprocessing - molded package, stacked die


3D Capability – Convex – Die Level

In Support of… • Laser/Photon EFA Tools

Convex/Curved die profile

• High NA SIL • Visible SIL (10 nm technology nodes & beyond)

• High-Throughput FIB processing • Design debug/circuit edit

Obtain uniform remaining silicon thickness!

• Nano/e-Probing Electrical failure analysis toolsets continue to develop at a pace significantly faster than sample preparation techniques. New solid immersion lenses (SILs) have been developed that require tighter tolerances of silicon thickness for imaging through the backside. Traditional silicon thinning sample preparation techniques that utilize a flat-plane grinding/polishing process do not account for the device bow and have become obsolete. High-precision sample preparation with the X-Prep® 3D produces uniform (edge-to-edge) remaining silicon thickness by following the natural curvature of the die. The device remains in its physical (manufactured) state and no thermal or mechanical stress/strain is introduced. The die may be thinned (without cracking) to any target thickness or to as little as 5 microns.


+/- 3 µm Uniformity & Ultra-thin

• High NA SIL • Optical Probing • SIMS

Dynamic relaxation of the package that occurs to the die as it is thinned causes the physical die profile to change, resulting in nonuniform remaining silicon thickness, or RST. Measurements of the substrate are therefore needed to adjust the physical tool profile to compensate for relaxation and allow thinning to tolerances better than +/- 3 microns from target thickness. The X-Prep® Vision™ measures the RST quickly and easily at the click of a button. The RST data is then used to modify the physical tool profile prior to polishing.

Thin silicon to optical transparency!

Operation – Intuitive, Versatile, Easy-to-Use The X-PrepŽ features a user-friendly, intuitive interface. As each screen appears in sequence, instruction is provided to the operator, ensuring every parameter and function is defined before operation so that no detail is overlooked. Graphic icons are found on many of the buttons for ease of identification. Help buttons on each screen provide access to additional explanation and instructions for each operation. This quickly provides a reminder and training to those who infrequently use the machine.

A Help (?) button on every screen provides specific instructions to the operator.

A high-definition (720p) color camera projects a magnified, razor-sharp image of the sample onto the touch-screen or external LCD monitor to help the operator define the X/Y boundary. The active display shows X + Y axis position as the stage moves the sample in reference to the crosshair. Zeroing enables measurements and sets the origin. The four-way arrows provide variable speed movement of the fixture/sample. Two buttons set X and Y distance to define the X/Y boundary. 12

Automatic Tilt Correction/Leveling Tilted


Automatic Sample Leveling Tilt adjustment (a standard feature) allows leveling the sample plane so it is parallel to the X/Y plane of the tool. Unevenly mounted or tilted samples can easily be leveled using this functionality. Contact on three points provides height data that is used to calculate the amount of adjustment needed. An automatic adjustment is made and it loops until the set tolerance has been achieved. Additional capability enables the operator to position the three points anywhere on the surface of the plane. The distance of lift between points can be set up to 20 mm to clear surface mount capacitors or other obstacles on the plane. The tolerance range can be defined from 0.5 to 100 Âľm. In cases where an angle other than parallel to the plane is desired, adjustment is also possible using the custom tilt function.

The difference in height between the points of contact on each axis are displayed on the touch-screen. Indication of tilt axis is provided by the +/- symbol/value.


System Information The X-Prep® is an ideal tool for any laboratory involved with precision sample preparation to support various analytical methods. It is exceptionally useful in supporting microelectronic device failure analysis labs. Additional applications can be found in the medical, MEMS and optical device/component fields. The table-top, compact footprint requires little space. The operation interface is simple to use, making it a more appealing tool to a greater number of people without any significant training. The wizard-based software guides the operator through a screen sequence to simplify use and reduce reliance on memory and skill. The information created can be captured and stored into the system memory and recalled for later use. Backup to a memory card ensures protection of data. Item No. 15-9550 15-9550-230

Accessories Fixtures Each fixture is designed to accommodate a carrier insert onto which samples are mounted using wax. Wax offers an advantage over clamping when dealing with delicate samples, or for those so small that clamping is not an option.

Borosilicate (glass) carriers maintain their shape through thermal cycling required to melt and harden wax. It is easily machined using diamond tools to produce pockets to accommodate items such as leads on device packages, capacitors or flip-chip die. Aluminum carriers can also be easily fitted into these fixtures and used as an alternative to glass for applications that require the carrier to provide electrical conductivity. All fixtures allow the sample to be submerged in lubricant to maintain lower temperatures for improved tool life and sample preservation as well as capturing particulates from becoming airborne.

Consumables – Cutting Metal & Circuit Board Carbide End Mills End mills are intended to be predominantly used to cut metal and/or metal alloys. Allied offers a complete line of solid carbide end mills whose item numbers appear in three (3) columns in the chart, each optimized for cutting the following three (3) material categories: PCB – FR4 Substrate Aluminum (Al) and/or Copper (Cu) Ferrous (Fe) Alloys – Steel, NiCo



Recommended for:  Aluminum, copper, ferrous (steel) alloys and titanium

The material composition of PCB (FR4) substrate requires an end mill that is durable enough to cut through not only the metal and resin, but also the glass fiber laminate. These tools are different than what is used just for pure aluminum or copper which conduct more heat that prematurely wears ordinary end mills. For ferrous (Fe) alloys (steel) require an even different tool type than what is used for other materials.

Consumables â&#x20AC;&#x201C; Precision Grinding Metal Bond Diamond Tools Metal bond diamond tools are recommended for grinding silicon and mold resins containing mineral and/or glass/silica filler. When compared with plated tools, bonded tools produce a finer surface finish and allow grinding closer to end point targets with significantly less damage. Bonded tools retain their shape and last longer than plated tools because as the bond and diamond layer wear, new diamond is exposed. As the tip wears, the geometry can be revived using the reshaping tool provided with the X-PrepÂŽ. All tools are 38 mm in length.
