Abstract: A double-sided integrated circuit chips, methods of fabricating the double-sided integrated circuit chips and design structures for double-sided integrated circuit chips. The method includes removing the backside silicon from two silicon-on-insulator wafers having devices fabricated therein and bonding them back to back utilizing the buried oxide layers. Contacts are then formed in the upper wafer to devices in the lower wafer and wiring levels are formed on the upper wafer. The lower wafer may include wiring levels. The lower wafer may include landing pads for the contacts. Contacts to the silicon layer of the lower wafer may be silicided.

Abstract translation: 双面集成电路芯片，制造双面集成电路芯片的方法和双面集成电路芯片的设计结构。 该方法包括从具有在其中制造的器件的两个绝缘体上硅晶片上去除后侧硅，并利用掩埋氧化物层将它们背对背地接合。 然后在上晶片中形成与下晶片中的器件接触，并在上晶片上形成布线层。 下晶片可以包括布线​​水平。 下部晶片可以包括用于触点的着陆焊盘。 与下晶片的硅层的接触可以被硅化。
