Patent TW-421792-B (TW)
Title: Built-in self-test circuit of memory device
Inventor: HUANG SHI-YU
IPC: G11C11/00
Filed: 1999-03-22
Granted: 2001-02-11
Abstract: This invention is about built-in self-test (BIST) circuit of memory device. For providing full-speed test, the operation speed of BIST circuit must match the testing speed of memory. Conventionally, a finite state machine is used for the test procedure generated by a set of predefined test evolution. If only using this finite state machine, the bottleneck of function performance will occur. For eliminating this bottleneck, we propose high-speed technique based on prediction logic. By using a prediction logic, certain specific signals of the clock threshold routes can be calculated before a clock cycle. By disposing flip-flop in these signals to break these threshold routes, the clock cycle time is reduced. Our synthetic results indicate that the proposed technique can be used to reduce the clock cycle time up to 30% and a 400 MHz design using 0.35 mu m CMOS cell program base is then introduced.

A spacer of an insulating layer is then formed on the side walls of the sacrificial pattern and the re-oxidation layer and impurity ions of a high concentration are implanted into the substrate of both sides of the spacer. Thereafter, an intermediate insulating layer is formed on the overall substrate and etched to expose the surface of the sacrificial pattern. The exposed sacrificial pattern is then removed to form a trench and a barrier metal layer is formed on the surface of the trench. Next, a refractory metal layer is formed so as to fill the trench on which the barrier metal layer is formed, to form a gate electrode having the polysilicon pattern, the barrier metal layer and the refractory metal. Furthermore, the sacrificial layer is formed to the thickness of 500 to 1,500 Å using a silicon nitride layer. The sacrificial pattern is selectively removed by wet etching using H3PO4.
