    Abstract: A method of etching a glass substrate using an etchant that is reversibly activated to etch only in precise locations in which such etching is desired and is deactivated when outside of these locations. The method involves exposing a first side of the glass substrate to a mixture of chemical substances that includes a neutralized etchant that is photosensitive. The neutralized etchant is formed by reacting a neutralizer with an etchant. The method also includes transmitting light from a direction of a second side of the glass into the mixture of chemical substances. In response to exposure to this light, the etchant is reversibly released from a bond to the neutralizer to form the etchant on predetermined areas of the first side of the glass, wherein the predetermined areas are defined by the dimension of the light.

    Abstract: Disclosed is a gallium arsenide (GaAs) enabled tunable filter for, e.g., 6 GHz Wi-Fi RF Frontend, with integrated high-performance varactors, metal-insulator-metal (MIM) capacitors, and 3D solenoid inductors. The tunable filter comprises a hyper-abrupt variable capacitor (varactor) high capacitance tuning ratio. The tunable filter also comprises a GaAs substrate in which through-GaAs-vias (TGV) are formed. The varactor along with the MIM capacitors and the 3D inductors is formed in an upper conductive structure on upper surface of the GaAs substrate. Lower conductive structure comprising lower conductors is formed on lower surface of the GaAs substrate. Electrical coupling between the lower and upper conductive structures is provided by the TGVs. The tunable filter can be integrated with radio frequency front end (RFFE) devices.

    Abstract: Improve EM coupling for the wafer-bonding process from a first wafer to a second wafer by a shielding technique. Examples may include building an EM shield implemented by BEOL-stacks/routings, bonding contacts, and TSVs for a closed-loop shielding platform for the integrated device to minimize EM interference from active devices due to eddy currents. The shield may be implemented in the active device layer during a wafer-to-wafer bonding-process that uses two different device layers/wafers, an active device layer/wafer and a passive device layer/wayer. The shield may be designed by the patterned routings for both I/O ports and the GND contacts.
