The method includes forming a high coefficient-of-thermal-expansion (CTE) layer on the first side of the silicon substrate. The high CTE layer has a CTE greater than the CTE of silicon. The method includes forming a buffer layer over the second side of the silicon substrate. The buffer ...
Gallium nitride on silicon (GaN-on-Si) technology is currently the industry-standard platform for commercial GaN power switching devices for wafer diameters up to 150mm/6-inches. Imec has developed GaN-on-Si power technology for 200mm/8-inch wafers and qualified enhancement-mode high-electron-mo...

Provided is a method of fabricating a semiconductor device. The method includes forming a first layer on a first side of a first silicon wafer. The first silicon wafer has a second side opposite the first side. The first layer has a coefficient-of-thermal-expansion (CTE) that is lower ...
Problem: low CTE, particularly glass with CTE close to CTE of silicon, and glass glass wafer having good dicing performance or cutting performance. Composition in the following molar%: SiO2: 60 to 85Al2O3: 1 to 17B2O3: 8-20Na2O: 0 to 5K2O: 0 to 5MgO: 0 to 10Cao: 0 to 10SRO...
The invention consists of a wafer-level expansion-matched design which forces a substrate to expand and contract at the same rate as a surface-mounted component, which reduces mechanical stress on the component. An embodiment of an expansion-matched MUX design consists of two pieces of silicon ...
(TFMB) exhibited no distinct glass transitions on the dynamic mechanical thermal analysis or a considerably high T-g exceeding 400 degrees C, extremely low CTE values close to that of silicon wafer or lower, and relatively low degrees of water absorption simultaneously in addition to excellent ...
The method includes forming a high coefficient-of-thermal-expansion (CTE) layer on the first side of the silicon substrate. The high CTE layer has a CTE greater than the CTE of silicon. The method includes forming a buffer layer over the second side of the silicon substrate. The buffer ...
