    摘要: In the present semiconductor integrated circuit device, a buffer is provided between a constant-current source circuit and an internal circuit that becomes a source of noise. The buffer controls the potential of an output node such that the potential of the output node becomes the bias potential. Even when noise is generated on the bias potential line when the internal circuit is in operation, the buffer dampens the noise. Thus, the noise generated in the internal circuit is prevented from adversely affecting the constant-current source circuit, and a stable operation of the internal circuit itself is achieved.

    摘要: A through-current Ic of a comparator circuit is switched in accordance with a response speed required with respect to a current consumption. Additionally, a through-current Is of a shifter circuit, which sends to the comparator circuit an output signal at an appropriate level transmitting a difference between an internal power supply potential Vdd and a reference potential Vref is switched according to the required response speed. When a device is in a standby state requiring a small current consumption in internal power supply potential Vdd, both through-currents Ic and Is are set small so that the whole current consumption can be further reduced.

    摘要: A Vpp level detecting circuit detects a potential on a Vpp trunk line which is provided commonly to a plurality of memory array banks for supplying a boosted potential thereto, and a boosted potential pump circuit supplies a current to the Vpp trunk line in accordance with a result of the detection. Since the position on the Vpp trunk line where the Vpp level detecting circuit performs the monitoring is substantially equally spaced from the respective memory blocks, an influence caused by an active state of the memory array bank can be suppressed during control of the potential on the Vpp trunk line.

    摘要: This invention provides a semiconductor device contrived to prevent a reference voltage and a reference current which are supplied to a high speed OCO from varying with a change in ambient temperature and/or a change in an external power supply voltage and to reduce the circuit area of a power supply module. The high speed OCO outputs a high speed clock whose magnitude is determined by the reference current and the reference voltage. A temperature sensor detects the ambient temperature of the high speed OCO and a voltage sensor detects the operating voltage of the high speed OCO. The power supply module includes a BGR and generates the reference voltage, reference current, and operating voltage of the high speed OCO, based on a primary reference voltage which is output by the BGR. A flash memory stores a table specifying trimming codes for the reference voltage and reference current, related to an ambient temperature and an operating voltage of the high speed OCO. A logic unit adjusts the values of the reference current and reference voltage, according to the reference voltage and reference current trimming codes related to the detected ambient temperature and operating voltage.

    摘要: Holes generated by impact ionization in a SOI-MOS transistor is removed from the channel region to improve the breakdown voltage between the source and drain. A channel region of the SOI-MOS transistor is formed of a p type silicon layer. A drain region is formed of an n type silicon layer. A source region adjacent to the channel region includes an n type germanium layer. The forbidden energy band gap width of the germanium is smaller than that of the silicon. The n type germanium layer is formed in at least a portion of the source region. This layer is formed by ion-implanting germanium into a portion of the silicon layer, or removing a portion of the silicon layer, followed by growing a germanium layer in an epitaxial manner thereabove.

    摘要: In a CMOS semiconductor device, a pMOS transistor and an nMOS transistor are formed on a single substrate. Each of the source/drain regions of the nMOS transistor and the pMOS transistor has LDD structure composed of a combination of a low concentration impurity region and a high concentration impurity region. The low concentration impurity region of the LDD structure of the pMOS transistor is formed in a self-align manner by ion implantation using a sidewall spacer with relatively thick film thickness. The low concentration impurity region of the LDD structure of the nMOS transistor is formed in a self-align manner by ion implantation using a relatively thin sidewall spacer as a mask. The sidewall spacer with thick film thickness of the pMOS transistor restrains that the channel between the source/drain regions is shortened due to thermal diffusion to cause punch through. As for the sidewall spacer of the nMOS transistor, its film thickness is selected to effectively restrain hot carrier effect in the vicinity of the drain and restrain degradation of current handling capability due to parasitic resistance to the minimum.

    摘要: In an MIS transistor of a type having LDD and salicide structures, the location of the boundary between the high and low impurity density source/drain regions and the positions of the salicide layers on the source/drain regions are independently controlled during fabrication using a double gate sidewall structure. An MIS transistor improved thereby has its boundary between the high and low impurity density source/drain regions at or displaced toward the control gate electrode with respect to the interface of the double gate sidewall structure.
