Microelectromechanical system (MEMS) devices and methods for forming MEMS devices are provided. The MEMS devices include a substrate, an anchored structure fixedly coupled to the substrate, and a movable structure resiliently coupled to the substrate. The movable structure has an opening formed therethrough and is positioned such that the anchored structure is at least partially within the opening and is in a capacitor-forming relationship with the movable structure. The movable structure comprises a movable structure finger extending only partially across the opening.

A method of forming a Micro-Electro-Mechanical System (MEMS) includes forming a lower electrode on a first insulator layer within a cavity of the MEMS. The method further includes forming an upper electrode over another insulator material on top of the lower electrode which is at least partially in contact with the lower electrode. The forming of the lower electrode and the upper electrode includes adjusting a metal volume of the lower electrode and the upper electrode to modify beam bending.

An integrated device package is disclosed. The package can include a carrier, such as first integrated device die, and a second integrated device die stacked on the first integrated device die. The package can include a buffer layer which coats at least a portion of an exterior surface of the first integrated device die and which is disposed between the second integrated device die and the first integrated device die. The buffer layer can comprise a pattern to reduce transmission of stresses between the first integrated device die and the second integrated device die.

The invention relates to a method for controlling stress in a substrate during laser deposition. The method includes the steps of: providing a laser deposition device including a chamber with a target holder with a target, a substrate holder with a substrate facing the target and a window, the laser deposition device further including a laser beam directed through the window of the chamber onto a spot at the target for generating a plasma plume of target material and depositing the target material onto a surface portion of the substrate in order to form a thin film of target material, wherein the target spot is movable relative to the substrate in order to deposit target material onto a plurality of surface portions of the substrate; defining a plurality of discrete surface portions on the substrate; aligning the target spot one after the other with each of the plurality of discrete surface portions and generating a plasma plume to deposit target material on each of the plurality of discrete surface portions; and adjusting at least one of the parameters of the deposition process depending on the discrete surface portion with which the target spot is aligned, which parameters include temperature, pressure, laser beam pulse duration, laser beam power, distance of target to substrate.
