•••9••• Innovationen Incredibly tough and heat-tolerant Innovative mix of materials and a special 3D trick: capacitor withstands 300 degree Celsius H eat is one of the worst enemies of electronics. It can disrupt functionality and cause electronic components to age mo- re quickly, or even destroy them. Now Fraunhofer researchers ha- ve developed a capacitor that can withstand temperatures of up to 300 degrees Celsius. They did so by using an innovative mix of ma- terials – and a special 3D trick. When manufacturing the con- ducting metal layers, the team etched tiny holes in the surface to increase its area. This 3D trick increases its capacity and simul- taneously makes it possible to use a thicker dielectric. A thicker layer withstands higher tempera- tures better and can decrease un- controlled leakage current in the capacitor. The experts are strik- ing new paths in the production of the insulating dielectric, too, by using tantalum pentoxide, a compound of tantalum (a metal) and oxygen and aluminium ox- ide. This mix of materials is bet- ter at storing charge carriers than the silicon oxide usually used, so it increases the capacitor’s ca- pacitance. For this reason, these particularly high-performing ma- terials are also sometimes called high-k dielectrics in electric en- gineering. In addition, the Fraun- hofer researchers use a highly electrically conductive silicon as well as ruthenium, which is es- pecially robust and heat-resist- ant. “With our material mix and design tricks, we can manufac- ture a capacitor that is incredibly tough and heat-tolerant without compromising performance,” ex- plains Dorothee Dietz, a scientist at Fraunhofer IMS. Yet the resistance to high temper- atures is not the only advantage that the semiconductor from the Fraunhofer lab offers. The capaci- tors are also manufactured using the metal-oxide-semiconductor (MOS) process, which works with layers that are just one atomic lay- er thick (atomic layer deposition). This makes it possible to precisely determine the overall thickness of the layers, “which makes pro- duction very flexible,” says Dietz. “The manufacturer can produce components exactly according to the customer’s specifications without having to change the flow of the process.” The heat-resistant capacitor withstands temperatures of up to 300 degrees Celsius.
