    Abstract: The present disclosure relates to a method of ultra-high voltage UHV device formation which utilizes a composite step oxide as a gate oxide to achieve isolation of the gate and drain-side spacer from the drain region. The thickness of the step gate oxide improves device breakdown voltage, and allows for the drain to be self-aligned to the gate, thus reducing device drift region and improves device on state resistance. The composite isolation layer comprises two or more dielectric layers which are formed through a series of deposition and etch steps including thermal oxidation and chemical vapor deposition. The composite isolation layer may then be etched to form a self-align structure which utilizes the spacers as hard mask to achieve a reduced device pitch relative to some prior art methods. A thicker gate oxide under one or both spacers can improve yield and high temperature operating life of the UHV device.

    Abstract translation: 本公开涉及一种利用复合步进氧化物作为栅极氧化物以实现栅极和漏极侧隔离物与漏极区隔离的超高压特高压器件形成方法。 步进栅极氧化物的厚度提高了器件击穿电压,并允许漏极与栅极自对准,从而减少器件漂移区域,并提高器件导通状态电阻。 复合隔离层包括通过包括热氧化和化学气相沉积在内的一系列沉积和蚀刻步骤形成的两个或多个电介质层。 然后可以蚀刻复合隔离层以形成自对准结构,其利用间隔物作为硬掩模以相对于一些现有技术方法实现减小的器件间距。 在一个或两个间隔物下面较厚的栅极氧化物可以提高UHV器件的产量和高温工作寿命。

    Abstract: A structure and a method of forming are provided. The structure includes a first dielectric layer overlying a first substrate. A first connection pad is disposed in a top surface of the first dielectric layer and contacts a first redistribution line. A first dummy pad is disposed in the top surface of the first dielectric layer, the first dummy pad contacting the first redistribution line. A second dielectric layer overlies a second substrate. A second connection pad and a second dummy pad are disposed in the top surface of the second dielectric layer, the second connection pad bonded to the first connection pad, and the first dummy pad positioned in a manner that is offset from the second dummy pad so that the first dummy pad and the second dummy pad do not contact each other.

    Abstract: Some embodiments relate to a three-dimensional (3D) integrated circuit (IC). The 3D IC includes a first IC die comprising a first semiconductor substrate, and a first interconnect structure over the first semiconductor substrate. The 3D IC also includes a second IC die comprising a second semiconductor substrate, and a second interconnect structure that separates the second semiconductor substrate from the first interconnect structure. A seal ring structure separates the first interconnect structure from the second interconnect structure and perimetrically surrounds a gas reservoir between the first IC die and second IC die. The seal ring structure includes a sidewall gas-vent opening structure configured to allow gas to pass between the gas reservoir and an ambient environment surrounding the 3D IC.
