摘要： Utilizing contact printing as the second exposure within a double exposure attenuated phase shift mask (APSM) fabrication process is disclosed. The process defines the shift pattern within the attenuated layer of the APSM using a first exposure, such as electron beam (e-beam) writing. The attenuated layer may be MoSi, MoSiO, and so on. The process then defines the border pattern within the opaque layer of the APSM using a second exposure. The second exposure employs contact printing, utilizing a contact exposure mask. The contact printing process may align the contact exposure mask over the wafer on which the APSM is fabricated utilizing a camera and an image storage system storing an image of this wafer.

摘要： A new transistor structure with thermal protection is provided. A type of the new transistor structure of the present invention includes a main depletion-mode NMOSFET and a control PMOSFET, with the drain terminal of the control PMOSFET connected to the gate terminal of the main NMOSFET and the gate terminal of the control PMOSFET connected to a thermal protection unit. The two-MOSFET structure as a whole emulates a normal NMOSFET. The source terminal of the control PMOSFET that's not connected to the gate terminal of the main NMOSFET acts as the gate terminal of the new transistor structure, and the drain and source terminals of the new transistor structure are the drain and source terminals of the main NMOSFET. The thermal protection unit prevents thermal failures of the MOSFETs of the new transistor structure by sensing heat, terminating current through and switching the two MOSFETs.
