Applications Guide PRECISION SAWING The production of quality cross-sections on package-level, wafer-level and board-level devices, generally begins with a saw cut. The quality of the precision sawing operation dictates the level of surface damage and the amount of surface features that are retained. The resulting surface may be an end in itself – a good sawed surface offers sufficient information for generating a Selected Area Preparation process – or a starting point for polishing. By optimizing the control of all parameters that affect cut quality, ULTRA TEC’s precision saws achieve an unbeatable match of performance and cost-effectiveness. Our saws range from a manually-fed trim saw to an advanced ‘Z-spindle’ semiautomatic unit that allows for multiple passes and precise height control. All our systems feature coolant provision for enhanced surface finishes and feed and speed controls.

Applications Guide DEPROCESSING As electronic device sizes become smaller, the deprocessing operation becomes more exacting. Over the last few years, metallization layers have moved into the sub-micron realm. This means that the one-micron resolution limit available with mechanical indicators has become essentially obsolete. ULTRA TEC has developed methods to ensure that sub-micron parallelism can be maintained – even down to 0.1 microns for die sizes less than 9mm. To tackle the other key weakness of previous systems in the marketplace – namely sample edge rounding – ULTRA TEC’s MULTIPOL system uses a true flat lapping CMP approach, as exemplified by multi-wafer CMP systems used in front-end operations. Using a harder, zero-nap, polyurethane-based pad material, allows for improved overall sample flatness and removes edge rounding.
Optical and mechanical measuring tools ensure parallel deprocessing on MULTIPOL polishing system.
Understanding that the majority of mechanical deprocessing in the world still takes with manual tools on manual polishers, ULTRA TEC are pleased to work alongside acknowledged preparation experts, Accelerated Analysis, to offer cost-effective manual tools. The new ULTRAPOL Basic manual polishing system provides the perfect polishing platform for optimized, no frills polishing consistency.

Applications Guide CROSS-SECTIONING Successful cross-sectioning techniques maintain the important information within the die or package, while being sufficiently controllable and reproducible so as to reveal the required features. Non-encapsulated cross-sectioning, particularly on die-level devices, is faster and and easier to perform than encapsulated techniques – and can yield suitable results for SEM analysis. ULTRA TEC’s offerings for cross-sectioning encompass manual tools and techniques, through to semi-automatic approaches, with advanced wedge angle and low-inertial sample loading controls. Our systems suit both encapsulated and nonencapsulated sample types. Techniques are available for the various key process steps of precision sawing, grinding, and polishing that allow for low-relief preparation of materials of often widely disparate hardnesses and mechanical properties.

Applications Guide
The increasing number metallization layers used in modern IC’s has caused frontside techniques to become inadequate for complete failure analysis. Backside imaging, i.e. imaging through the silicon substrate, allows access to all the transistors within an IC and so can complete the analytical picture. Backside imaging is possible as pure silicon is transparent at near infra-red wavelengths. Dopants added to the silicon substrate reduce this transparency. This means that to image a modern die effectively with a backside microscope generally requires the planar thinning, and subsequent polishing, of the substrate to make imaging and thus backside analysis possible. To enable backside analysis on packaged or encapsulated dice requires decapsulation and heat sink milling prior to substrate thinning. ULTRA TEC has developed processes and equipment that allow for effective low damage backside preparation techniques for dice of all sizes and with all encapsulation techniques.

Applications Guide BACKSIDE PREPARATION …continued
Optimizing All Backside Microscopes BEFORE ARC
After producing a mirror polish on the decapsulated and substrate-thinned package/die, the resulting sample may be backside imaged under NIR. However, the glare from the polished surface reflected into standard objective lenses often means that good image contrast is impossible. The addition of an antireflective coat (ARC) provides both improved contrast and moreover a significant increase in the photon efficiency evident from emission sites. Until recently ARC required expensive sputtering equipment and subsequent baking at highly elevated temperatures. After extensive research and development to help our customers optimize the entire backside sample preparation process, ULTRA TEC introduced a technology solution that put quality ARC’s within easy reach of every sample preparation laboratory. The industry’s first product to feature the technology is ARC-lite. The system offers a fast (less than one minute), one-step, room temperature, chemical process that can be modified by the user to enhance coatings for the various observation wavelengths. The range of imaging fluids includes a standard solution, and also a highly thermal stable, "FIB friendly", solution.

Applications Guide DECAPSULATION Topside Decapsulation, by primarily chemical means, is a well-established application that is carried out with manual protocols, or more frequently with automated acid etch systems. These methods produce fast and effective results on standard plastic packaged parts. Several factors, however, make acids incapable of processing all package styles. For instance, when the package contains materials that are slow or impossible to remove with acids, or when the total packaging cross-sectional thickness is large – thus exacerbating the non-directionality of acid attack and potentially leading to harmful corrosion of bond pads and wires – it has been found that initial mechanical decapsulation offers key advantages. After finding more and more decapsulation applications that benefit from initial mechanical operations, ULTRA TEC have developed processes for MCM, Stacked die CSP/MCP's, power devices etc. based on the ASAP product platforms. The new ASAP-decap system provides control of all required parameters to increase electrical survivabilty and yield on many decapsulation applications.

Selected Area Preparation ASAP-1 Backside Preparation & Mechanical Decapsulation The ability to produce accurate, reproducible, thinned dice for backside analysis is now available for every laboratory. Flip-chip and power chip mechanical decap is now straightforward and accurate. The die, whether in packaged or wafer form, is mounted on a traveling table that oscillates within X and Y direction limits set by the user. Utilizing a rotating tool, controlled in the Z-Direction, accurate, reproducible grinding can be carried out to a specific thickness, finishing with a scratch-free mirror polish (when required). The SAP process yields a surface suitable for imaging and backside microscopy. Damage and heating of the substrate is minimal during processing due to the extreme low damage nature of the process. This leads to improved sample yield.

Selected Area Preparation ASAP-1 IPIP TTEECCHTT
Selected Area Preparation of Wafers Backside preparation of a single die on a full wafer is often required for yield enhancement or failure analysis purposes. To make this possible, a wafer stage is available for ASAP-1. The standard tilt table is removed to allow for the wafer stage. Preparation is generally a four step process (1 grind and 3 polishing steps). This yields an optimized polished surface ready for backside imaging.
Frontside probing on a standard or inverted probe station can be used to bias the wafer for backside analysis, but the thinned wafer must be made strong enough to withstand the pressures exerted by probe tips, while still being optically transparent for backside analysis. ULTRA TEC has developed a special technique for re-strengthening wafers using a UV curing optical epoxy and glass cover slip. A typical re-strengthened wafer cavity is shown in the photograph to the right.

Decapsulation ASAP - decap MECHANICAL DECAP ASAP – decap produces parts with vertical walls & unmatched control of material removal depth – to 5 microns accuracy. This helps ensure the electrical survivability of decapsulated parts. Mechanical Decapsulation offers key advantages for several performance issues seen with chemicalonly approaches. For instance, thick packages are just as effective to decap as thin packages; very small cavities can be opened; and traditionally ‘difficult’ materials may be processed quickly and easily by mechanical means. The processed parts can be either an end in themselves or the starting point for either manual etch stations or automated decapsulation systems. The system furthermore provides a key starting point for Reactive Ion Etch (RIE or ‘Dry Decap’) Processes – enabling them to be time-competitive with wet methods.
