  • Patent number: RE47170
    Abstract: Semiconductor patterns are formed by performing trimming simultaneously with the process of depositing the spacer oxide. Alternatively, a first part of the trimming is performed in-situ, immediately before the spacer oxide deposition process in the same chamber in which the spacer oxide deposition is performed whereas a second part of the trimming is performed simultaneously with the process of depositing the spacer oxide. Thus, semiconductor patterns are formed reducing PR footing during PR trimming with direct plasma exposure.

  • Patent number: RE47382
    Abstract: A method is provided for forming a metal/semiconductor/metal (MSM) back-to-back Schottky diode from a silicon (Si) semiconductor. The method deposits a Si semiconductor layer between a bottom electrode and a top electrode, and forms a MSM diode having a threshold voltage, breakdown voltage, and on/off current ratio. The method is able to modify the threshold voltage, breakdown voltage, and on/off current ratio of the MSM diode in response to controlling the Si semiconductor layer thickness. Generally, both the threshold and breakdown voltage are increased in response to increasing the Si thickness. With respect to the on/off current ratio, there is an optimal thickness. The method is able to form an amorphous Si (a-Si) and polycrystalline Si (polySi) semiconductor layer using either chemical vapor deposition (CVD) or DC sputtering. The Si semiconductor can be doped with a Group V donor material, which decreases the threshold voltage and increases the breakdown voltage.
