These steps add time and complexity and can limit compatibility with certain materials.<\/p>\n<p>The new embedded silicon test structure from Chipmetrics introduces a lift-off style measurement approach that completely bypasses these requirements.<\/p>\n<p>With the Chipmetrics structure, researchers can go directly from deposition to measurement in minutes.<\/p>\n<p>Key benefits include:<\/p>\n<ul>\n<li>No photolithography or etching required<\/li>\n<li>Compatible with virtually any thin-film material<\/li>\n<li>Immediate electrical testing after deposition<\/li>\n<li>Customizable layouts for application-specific measurements<\/li>\n<\/ul>\n<p>By eliminating multiple fabrication steps, the structure significantly reduces the time required to acquire electrical data during thin-film process development.<\/p>\n<h3 class=\"\">Proven measurement capability<\/h3>\n<p>The electrical test structure was validated in collaboration with the TU Dresden, Chair of Nanoelectronics (Prof. Martin Knaut).<\/p>\n<p>In initial experiments, the structure was used to measure the electrical properties of an 8.7 nm thick PEALD-TiN film deposited on 46 nm Al\u00b2O\u00b3 using a four-point probe measurement configuration.<\/p>\n<p>These tests confirmed that the structure enables accurate measurement of sheet resistance and resistivity, demonstrating its suitability for the characterization of advanced thin films.<\/p>\n<h3 class=\"\">Broad range of electrical characterization capabilities<\/h3>\n<p>The test structure supports a variety of electrical measurements, including:<\/p>\n<ul>\n<li>Film resistance and resistivity<\/li>\n<li>Contact resistance<\/li>\n<li>Hall coefficient measurements<\/li>\n<li>Temperature coefficient of resistance (TCR)<\/li>\n<li>Magnetoresistance<\/li>\n<li>Electromigration testing<\/li>\n<\/ul>\n<h3 class=\"\">IV-Linearity and self-heating characterization<\/h3>\n<p>This versatility makes the structure valuable for both academic research environments and semiconductor process development laboratories.<\/p>\n<h3 class=\"\">Accelerating material and process development<\/h3>\n<p>As semiconductor devices continue to be miniaturized and new materials are introduced, fast electrical feedback is becoming increasingly important.<\/p>\n<p>By eliminating post-deposition patterning steps, the Chipmetrics test structure enables researchers to evaluate the electrical performance of new materials and deposition processes faster than ever before.<\/p>\n<h3 class=\"\">About Chipmetrics<\/h3>\n<p>Chipmetrics Oy develops and supplies metrology solutions for manufacturing processes in the semiconductor industry, focusing on innovative measurement chips and ALD measurement services.
