Title: Douglas P. Verret: Innovator in Integrated Circuit Technology
Introduction
Douglas P. Verret is a prominent inventor based in Sugarland, TX (US), known for his significant contributions to integrated circuit technology. With a total of 16 patents to his name, Verret has made a lasting impact in the field of electronics.
Latest Patents
His latest patents include innovations in well resistors and polysilicon resistors. An integrated circuit containing a well resistor features STI field oxide and resistor dummy active areas within the well resistor. STI trenches are etched and filled with trench fill dielectric material. The trench fill dielectric material is subsequently removed from over the active areas by a CMP process, leaving STI field oxide in the STI trenches. Following this, dopants are implanted into a substrate in the well resistor area to form the well resistor. Additionally, an integrated circuit containing a polysilicon resistor has STI field oxide and resistor dummy active areas designated for the polysilicon resistor. A layer of polysilicon is formed and planarized through a CMP process. A polysilicon etch mask is then created over the CMP-planarized polysilicon layer to define the polysilicon resistor. A polysilicon etch process removes polysilicon in areas exposed by the polysilicon etch mask, resulting in the formation of the polysilicon resistor.
