Latest Patents

One of his latest patents is titled "Low Congestion Standard Cells." This patent describes a system and method for creating layouts for standard cells. In various implementations, a semiconductor fabrication process forms a power signal route in the same metal zero track reserved for power rails. The process also forms a contact layer with inserted spacing underneath the power signal route. This contact layer has physical contact with the power signal route at a first distance greater than the width of any signal route in any metal layer orthogonal to the power signal route. Additionally, it has no physical contact with the power signal route at a second distance greater than the width. One or more signal routes in the local interconnect layer are routed through this spacing, which helps to reduce signal congestion.

Another significant patent by Pratap Kumar Das is focused on "Techniques to Create Power Connections from Floating Nets in Standard Cells." This patent outlines a system and method for creating layouts for standard cells. In this implementation, a floating metal net in the metal zero layer of a standard cell is selected for conversion to a power rail. The semiconductor process forms a power rail in a metal zero track reserved for power rails and another power rail in a metal zero track reserved for floating metal nets. The two power rails are electrically shorted using a local interconnect layer, which decreases the charging and discharging times of a source region physically connected to both power rails.
