The present disclosure provides an embodiment of an integrated structure that includes a first electrode of a first conductive material embedded in a first semiconductor substrate; a second electrode of a second conductive material embedded in a second semiconductor substrate; and a electrolyte disposed between the first and second electrodes. The first and second semiconductor substrates are bonded together through bonding pads such that the first and second electrodes are enclosed between the first and second semiconductor substrates. The second conductive material is different from the first conductive material.

Semiconductor structures having a micro-battery and methods for making the same

The present disclosure relates to a method of chemical vapor deposition (CVD). In some embodiments, a process gas is applied into a vacuum chamber. The process gas is guided downstream the vacuum chamber through a shower head arranged under the gas import, where the process gas is redirected to be laterally unevenly distributed under the shower head. A density of the process gas increases from a center region to a peripheral region of the vacuum chamber. The process gas is then deposited onto a first substrate to form a precursor material with an uneven thickness profile as a result of uneven distribution of the process gas. The shower head has multiple control zones each having a plurality of holes disposed through the shower head.

CVD apparatus with multi-zone thickness control

The present disclosure relates to a chemical vapor deposition apparatus and associated methods. In some embodiments, the CVD apparatus has a vacuum chamber and a gas import having a gas import axis through which a process gas is imported into the vacuum chamber and being arranged near an upper region of the vacuum chamber. At least one exhaust port is arranged near a bottom region of the vacuum chamber. The CVD apparatus also has a shower head arranged under the gas import having a plurality of holes formed there through. The shower head redistributes the process gas to form a precursor material with an uneven thickness that matches a remove profile of a subsequent CMP process. As a result, planarity of the formed layer after the CMP process is improved.

A method of fabricating a micro electro mechanical system (MEMS) structure includes providing a first substrate structure including a bonding pad structure. The bonding pad structure has at least one recess therein. A second substrate structure is provided and bonded with the bonding pad structure of the first substrate structure.

Methods of fabricating micro electro mechanical system structures

A wafer seal ring may be formed on a first and/or a second wafer. One or both of the first and/or second wafers may have one or more dies formed thereon. The wafer seal ring may be formed to surround the dies of a corresponding wafer. One or more die seal rings may be formed around the one or more dies. The wafer seal ring may be formed to a height that may be approximately equal to a height of one or more die seal rings formed on the first and/or second wafer. The wafer seal ring may be formed to provide for eutectic or fusion bonding processes. The first and second wafers may be bonded together to form a seal ring structure between the first and second wafers. The seal ring structure may provide a hermetic seal between the first and second wafers.
