Title: Three-stage etching for contact window
Inventor: O HO
IPC: C23F4/00
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To obtain a practical aluminum step coverage by respectively performing anisotropic etching, isotropic etching, and anisotropic etching in first, second, and third stages by specifying the ratios of the etching depths in the three etching stages to the total etching depth. SOLUTION: In a first stage, a contact window 41 is formed in an oxide layer 14 by anisotropic etching and, in a second stage, the window 41 is enlarged to a contact window 42 by isotropic etching. In a third stage, the window 42 is further enlarged to a contact window 43 by anisotropic etching. The longitudinal magnification (namely B/A+B) of the contact window 43 formed in the third stage is limited to about 50%. Since the contact window 43 has a small longitudinal magnification, the corners 44 of the window 43 can be smoothed by performing an annealing process in a low-oxygen atmosphere. Therefore, an aluminum coating layer is not fractured.

Filed: 1987-07-17
Abstract: PURPOSE:To suppress the reduction in the entire throughput of the system by using a processor exchanging a data with a main processing unit through a dual port RAM so as to manage the software timer independently of the master processing unit. CONSTITUTION:When a timer management request is inputted from a master processing unit via a RAM 5, a processor 1 generates a task management block comprising an ID and a timer value and stores a timer queue in a matrix of a RAM 3 based on a program of a ROM 2. When an interrupt is given from the timer 4, the timer value of the task management block is decremented by the processor 1 and it is informed from the processor 1 to the master processing unit via the RAM at timeout and the management of the software timer is applied by the processor 1 independently of the master processing unit. Thus, the deterioration in the through time of the entire system due to the timer interrupt processing time longer than the task time is suppressed.

Title: Reference voltage generation circuit
Inventor: TAMAGAWA AKIO
IPC: G05F1/46
Filed: 1989-07-11
Abstract: PURPOSE:To omit a start-up resistance by permitting an input differential couple to use the operational amplifier of Pch transistor (Pch Tr) with an Nch transistor (Nch Tr) differential couple. CONSTITUTION:When an output voltage VR is OV, the gate potentials of Nch Tr 11 and 12 come to OV, and they are turned off. Thus, the gate potentials of Pch Tr 16 and 17 rise to a power voltage level and they are turned off. Consequently, the gate potential comes to OV by an output stage Tr, and the output voltage VR rises, whereby it is stabilized at a first operation point. Since the circuit does not require the start-up resistance of a high resistance, which has a wide area, the dependency of the output voltage for a power voltage can be eliminated.
