    摘要: A mask, which does not require additional reticles, and a method of using the mask for recovering alignment marks in a wafer after an inter-level dielectric layer has been planarized and a second layer of metal has been deposited on the planarized inter-level dielectric layer are described. An alignment mark protection pattern and a clearout window pattern are sub-divided so they can be formed from a first and a second mask element. These mask elements can be formed in the peripheral region of the reticle used to pattern the device region of the wafer. The mask elements are used to expose the alignment mark protection pattern in a first layer of photoresist and the clearout window pattern in a second layer of photoresist.

    摘要: A voltage regulator includes an amplifier, a power device, a delay signal generator, and a voltage-generating circuit. The amplifier generates a control signal according to a reference voltage and a feedback voltage. The power switch generates the output voltage by regulating the output current according to the switch control signal. The delay signal generator generates a plurality of sequential delay signals each having distinct delay time with respect to an externally applied power-on burst signal. The voltage-generating circuit provides an equivalent resistance for generating the feedback voltage corresponding to the output voltage, and regulates the output voltage by adjusting the equivalent resistance according to the plurality of sequential delay signals.

    摘要: A mask pattern and method are described for the recovery of alignment marks on an integrated circuit wafer without the use of additional masks. The mask pattern and method provide means to recover the alignment marks after forming a metal layer on a planarized inter-level dielectric layer. The pattern which conventional methods have placed on a separate mask is formed in the end regions of a mask used for forming a pattern on the active region of the wafer. In order to fit the pattern in the end regions of the mask the pattern is divided into two parts. When the pattern is used to expose a layer of photoresist two exposure steps are used.

    摘要: The present invention provides a method of removing an shallow trench isolation (STI) oxide layer 38 from over alignment marks 30. The invention has two major features: (1) A STI photoresist mask 42A that is used to etch Alignment area trenches 34 around alignment marks 30 and to etch STI trenches 35 in device areas 14; and (2) A "reverse tone" STI photoresist mask 42B that is used to remove the isolation oxide 38 from over the alignment marks 30 and from over the active areas 37. The method begins by providing a substrate 10 having a device area 14, an alignment mark trench area 16; and an alignment mark area 18. A polish stop layer 20 22 is formed over the substrate 10. A trench isolation resist layer 42A is used to etch alignment area trenches 34 around the alignment marks 34 and STI trenches 35 in the device areas. A dielectric layer 38 is formed over the substrate. In a key step, the reverse tone trench isolation resist layer 42B is used to etch the first dielectric layer 38 from over the alignment marks 30 and the Active areas 27. Next, the remaining first dielectric layer 38 is chemical-mechanical polished thereby planarizing the first dielectric layer 38.
