Patterning photoresist with extreme control over dose and placement is the first crucial step in semiconductor manufacturing. However, how can the activation of modern complex resist components be accurately measured at sufficient spatial resolution? No exposed nanometre-scale resist pattern is sufficiently sturdy to unalteredly withstand...

The semiconductor industry needs to fit ever more devices per unit area to improve their performance; hence a trend towards increasingly complex structures by varying material combinations and 3D geometries with increasing aspect ratios. The new materials used may be optically opaque, posing problems for traditional optical metrology methods....

Several methods are being researched to detect and characterize buried nanoscale structures in hard solid samples. The most common acoustic method is acoustic microscopy. An acoustic microscope is based on a single element transducer operating in pulse-echo mode. The acoustic waves are coupled into a sample using a liquid couplant (eg water) and...

While Atomic Force Microscopy is mostly used to investigate surface properties, people have almost since its invention sought to apply its high resolution capability to image also structures buried within samples. One of the earliest techniques for this was based on using ultrasound excitations to visualize local differences in effective tip...

In semiconductor manufacturing, the shrink following Moore's law requires ever tighter overlay and registration between the different (material) layers. For accurately characterising this overlay and registration, TNO has developed a large dynamic range atomic force microscope demonstrator; the LDR-AFM can measure marker-to-feature distances...

The characterization of buried nanoscale structures nondestructively is an important challenge in a number of applications, such as defect detection and metrology in the semiconductor industry. A promising technique is Subsurface Scanning Probe Microscopy (SSPM), which combines ultrasound with Atomic Force Microscopy (AFM). Initially, SSPM was...

This technique uses an Atomic force microscope (AFM) to map the elastic properties of buried materials with high spatial resolution. Ultrasound excitation is applied to the tip-sample interface in the AFM, while the probe’s dynamic response is monitored. The excitation is a carrier of high frequency fc, that is amplitude-modulated at a lower...

Scanning Probe Microscopy (SPM) has emerged as a metrology solution for the semiconductor industry enabling high throughput defect review and high resolution 3D metrology. TNO has developed a Subsurface Ultrasonic Resonant Force Microscopy (SSURFM) for non-destructive, high resolution imaging of features buried under one or more layers of...

TNO developed a novel Large Dynamic Range Atomic Force Microscope (LDRAFM), designed for sub-nm accurate metrology. The current work provides an overview of recent developments and presents the results obtained after final integration of the complete system. Results indicate impressive stability over long range, enabling subnm metrology...

In order to make stiffness based subsurface AFM a quantitative imaging modality, the experimental subsurface measurement must be interpreted with a versatile forward (and inverse) model. We have developed a fully parametric finite element model framework for the quantification of critical dimensions relevant in semicon applications. After...

In this paper, we present an AFM based subsurface measurement technique that can be used for overlay and critical dimensions (CD) measurements through optically opaque layers. The proposed method uses the surface elasticity map to resolve the presence and geometry of subsurface structures. To improve the imaging performance of the AFM based...

Extracting quantitative information about dimensions and material properties of buried structures is continuing to be an important but difficult task in metrology. Examples of questions asking for this capability include critical dimension metrology of fins such as the profile (bottom width, top width, height) or the presence and extent of voids...
